My Auto Biography

My head has been compared to a squirrels because of its similar features; however, my organs are also located in this cavity. I eat seeds and plankton so I do not need a large stomach. My 8 cartilaginous arms are used for long distance travel and have brown waterproof fur everywhere except around my gills, which are on the bottom of each. I also have wings, which are waterproof along with my fur. I use these for short distance travel because i can not breath for long above water. I tend to use my arms when I move annually to a colder climate. I prefer the cold, that is why I have fur to keep me warm.

Biomolecules


The biomolecules found in found in avocado are fat protein and simple sugars. In egg white biomolecules are protein and simple sugars. The egg yolk contains the biomolecules fat protein and simple sugars. I learned that not all foods contain the same amount of biomolecules and some dont have any of one group at all. Avocado stayed pretty consistent in the catalase activity but it varied between each of the biomolecules.

Catalase activity


Do different enzymes react differently to different temperatures?

Yes enzymes react differently due to different tempuratures, because they all do different jobs for the body and have different triggers. -http://www.ask.com/wiki/Enzyme

A. [|http://www.glencoe.com/sec/science/cgi-bin/splitwindow.cgi?top=http://www.glencoe.com/sec/science/top2.html&link=http://www.educationusingpowerpoint.org.uk/Animations/rates of reaction.html] Explain how heat affects the rate of reaction. Heat speeds up the reaction rate. Explain how surface area affects the rate of reaction. Surface area affects the rate of reaction because the cells bang into the increased surface area making it harder to move. Explain how concentration affects the rate of reaction. Concentration affects the rate of reaction because the cells bang into each other more making it harder to move.

B. Go to the following site: [] What types of molecules make up enzymes? Proteins make up enzymes. What determines the function of an enzyme? The shape and molecules present determine the function of an enzyme. What is denaturing? When high tempuratures or extreme pH values affect the shape of an enzyme molecule. Describe how a reaction takes place without an enzyme and then with an enzyme. A reaction takes place without an enzyme if the molecules come together at just the right angle. A reaction takes place with an enzyme because the molecules are attracted to the enzyme and fit properly. Explain how you think an enzyme might speed up a reaction. An enzyme might speed up a reaction since the molecules that are designed for it are attracted to it and that cuts down on time. Explain why you think enzymes are so particular about reactions. Because they have to be a certain shape for a reaction to occur. How is the shape of an enzyme important? The shape determines what molecules it can react with. Explain how you know an enzyme is reusable. An enzyme is reusable because it can form bonds multiple times. How does heating an enzyme affect its function? Heating an enzyme changes the shape of the enzyme so that it is now useless to the molecules it reacts to. Does heating an enzyme always have the same effect when the catalyst needs to act on a substance? Explain. Yes it does because the catalyst cannot be put into the enzyme because the enzymes shape is messed up.

C. Go to: [] [] Explain the difference between hydrolysis and condensation (dehydration). Which molecules from our labs undergo these reactions? Hydrolisis is when a large molecule is being broken down. The result is a monomer. Condensation builds large molecules. This makes a polymer and a water molecule.

D. [] What are proteins made of? Amino acids What chemical process creates the proteins? Describe how proteins are made in detail. Sketch a picture. Proteins are made when a string of amino acids are put together with peptide bonds.

Light intensity

 * Homework: ** Create a data table that outlines % maximal ATP, ATP created in your time frame used, light intensity, and wavelength. You can also take screen shots while it is in action and display your data in a graph or other ways if desired.


 * || % max. ATP || ATP created || Light Intensity || Wave length ||
 * Test 1 || 6% || 1 || 100 || 575 ||
 * Test 2 || 0% || 0 || 0 || 400 ||
 * Test 3 || 3% || 1 || 200 || 750 ||
 * Test 4 || 65% || 3 || 200 || 400 ||
 * Test 5 || 100% || 5 || 200 || 425 ||

Research background information about light intensity-luminous intensity measured in candlepower wavelength-distance between successive crests of a wave energy-the capacity to do work pigment colors-any substance that colors tissues or cells of animals or plants

Explain the following: how wavelength and light intensity is important for photosynthesis. Be certain to completely relate these to the light reaction and what you observed in the simulation. Light intensity is important to photosynthesis because when it is high it makes sugar faster because it speeds up photosynthesis. Wavelength is the color you see in the plant. This is important because sunlight is attracted to different colors.

A summary of what you learned through the simulation. You can discuss using paragraphs, data tables or pictures (include a brief statement as well). I learned that there is a lot more involved in photosynthesis than light just hitting a plant. Color wave length and light intensity all come into play on how well a plant absorbs sunlight.

Photosynthesis Webquest
1. What is photosynthesis? A process that converts carbon dioxide into organic compounds using energy from sunlight. 2. What types of organisms carry out photosynthesis? List 3 groups. Plants algae and bacteria 3. What is the chemical equation for photosynthesis? What is the translation for the chemical equation? 6H 2 O + 6CO 2  --> C 6 H 12 O 6 + 6O 2 4. Look at your equation in number 3 and answer the following questions: a. What are the raw materials or reactants needed to carry out photosynthesis? Carbon dioxide and water b. What are the products of photosynthesis? phosphoglyceraldohyde/glucose and oxygen. What energy source is needed in the reaction? sunlight 5. Consider a plant as the photosynthetic organism. a. In what part of the plant does photosynthesis occur? leaf b. What specific cells are involved? mesophyll c. What specific organelle is involved? chloroplasts 6. How does the plant get the raw materials needed for photosynthesis to the plant part where photosynthesis occurs? water comes from the roots and carbon dioxide comes in through the stomata 7. What is a stoma and of what value is the stoma to the plant in its efforts to carry out photosynthesis? The stoma carries carbon dioxide to the cell through the leaves. 8. Explore the organelle that is responsible for the process of photosynthesis. What are found inside the organelle and how do these parts aid in the process of photosynthesis? There is stroma and in the stroma is the thylakoid there is also chlorophyll. The stroma holds the thylakoid and the thylakoid holds the chlorophyll. Chlorophyll is green and attracts sunlight.

9. What is the first part of photosynthesis called and where does it occur? The first stage is the light stage and it occurs in the thylakoid membranes. 10. What exactly happens in the first part of photosynthesis? Chlorophyll losses a water molecule then they produce an ATP molecule then their energy state is raised as they start to rest. 11. What is the second part of photosynthesis called and where does it happen? The calvin cycle which occurs in the stroma 12. What happens in the second part of photosynthesis? PGAL is made when carbon dioxide hydrogen and ATP comes together 13. Are the two parts of photosynthesis connected? If so, explain the connection. Yes they are because the excitement caused from the first stage leads to the 2nd stage. 14. Does the chemical equation that you listed in number 3 tell the entire story of the process of photosynthesis? Why or why not? No it does not because it doesn’t tell which bonds are where. it is more involved also

Yeast Lab
Analysis: 1. State 2 clear, concise conclusions derived from the analysis of the results from the experiments in your class. · There is such a thing as to much sugar because the cells cannot burn it as fast as they need to. · There is also such a thing as to little sugar because the cell isn’t supplied with enough sugar to burn. 2. What was the dependent and independent variables in the experiment? Explain. · Independent-yeast · Dependant-sugar and water 3. According to the experimental data, what kind of environment do yeast prefer? How did the sugar concentration change the result? Explain. · A warm moist enviroment 4. How did the amount of rising change with the different types of sugar solutions used? · The smallest amount of sugar and the largest amount of sugar either flattened or stayed flat and hard however the 5% sugar solution puffed up and looked very good to eat. 5. What kind of respiration did the yeast carry out in the experiment? Explain. · Propionic respiration because yeast is a bacteria it gives off ethanol however the ethanol is baked out of the bread.



Genetic disorders
Click on your disorder in the [|chart]. Sign up on the paper in class. In order to better understand different genetic irregularities, you will research and summarize a genetic condition of your choice. Explain the following: 1. What causes this condition? (There are two ways to look at this one - In terms of DNA, what causes the irregularity, and also, what can trigger this genetic change?) Damage to the villi in your stomach Inherited (if someone in your immediate family has it you have a 5-15% chance of getting it Many times the disease emerges after some form of trauma  2. How is it diagnosed?  People with celiac disease carry higher than normal levels of certain antibodies (anti-gliadin, anti-endomysium and anti-tissue transglutaminase). People with celiac disease recognize the celiace as a foreign substance so they produce more antibodies to get rid of it.   3. Who gets this disorder? Discuss percentages, subgroups of people, etc. Is the disorder genetic in nature or is it caused by something environmental?  Anyone can get this but it seems to be mostly genetic and if someone in your immediate family has it you have a 5-15% chance of getting it. It is caused by damage to the villi in your stomach causing the antibodies to attack the gluten put into your stomach. (1/3000 people in the United States 4. What are the symptoms of this disorder? There are no typical signs and symptoms but most people with the disease complain of irregular diarrhea, abdominal pain, and bloating. Some of the other symptoms resemble that of irritable bowel syndrome, gastric ulcers Crohn’s disease, parasite infections, anemia, skin disorders or a nervous condition ( Irritability or depression Anemia Stomach upset Joint pain Muscle cramps Skin rash Mouth sores Dental and bone disorders (such as osteoporosis) Tingling in the legs and feet (neuropathy). Some indications of malabsorption that may result from celiac disease include: Weight loss Diarrhea Abdominal cramps, gas and bloating General weakness and fatigue Foul-smelling or grayish stools that may be fatty or oily Stunted growth (in children) Osteoporosis Anemia 5.Summarize other information that is important.  People with celiac disease have to be put on a special gluten free diet where wheat barley rye modified food starch malt and oats  6. What level is your disorder? Use this [|chart]. ? ni idea []
