=Creating an Organism=

Jimothy is the name I gave the new organism I discovered. I found him along the Amazon River in the rain forest. He was eating some ferns. I tried to be quiet so I didn’t disturb him but clumsy me tripped over a mushroom and he stood at alert with the hair on his back standing straight up. He was an interesting creature. He had a long trunk sort of like an elephant, hooves and a long muscular body, and a tail that sort of looked like a fin. He seemed to be a very friendly animal so I approached him with circumspect. When he saw me he flapped his large ears and flew over to where I had stopped in my tracks. As soon as his feet touched the ground he used his trunk to lift me up and onto his back. We flew into the air and landed near a watering hole where I jumped off his back. Then, he ran into the water and used his “fin” to swim gracefully through the water. Soon he was completely submerged in the water. He had to have been down there for 5 minutes when he finally came back out of the water with 5 other organisms just like him. I couldn’t believe my eyes! I hurried up and grabbed my camera and took a picture of them playing in the water. I hurried back to the plane I had gotten there in and flew back to the lab. Once there I told my story about how I had discovered Jimothy and now there is a not well know organism called a horelfish but scientists would refer to it as //Elephas// //Equidae Osteichthyes.//

=Catalase Lab= I think that Apple 5 and Apple 6's data is not accurate because all of the other 4 apples were rated 1 on all 3 tests. I was surprised the apple didn't react to any of the 3 tests. 2/3 of the results say that apples do not have catalase in them. What is hydrogen peroxide used for other than to clean cuts? Hydrogen peroxide is also used as an aniseptic, an oxidizer, and in rocketry as a propellant. http://en.wikipedia.org/wiki/Hydrogen_peroxide

=Biomolecules Lab=

I tested the Apple and the Peas. I discovered an apple contains simple sugar. I also found that peas contain starch and lipids. I think that foods with protein and fat in them contain catalse because the foods that had high catalase reactions also contained proteins and fat. I learned that Apples contain fat. I didnt know that.

B. Go to the following site: [] C. Go to: [] [] D. [] E. [] F. [] G. [] H. []
 * 1) What types of molecules make up enzymes?
 * 2) proteins
 * 3) What determines the function of an enzyme?
 * 4) The enzymes shape (activation energy- energy required for reaction)
 * 5) What is denaturing?
 * 6) The process that makes enzymes less effective or not effective at all (shape is changed)
 * 7) Describe how a reaction takes place without an enzyme and then with an enzyme.
 * 8) Without an enzyme a reaction takes a while because the molecules need to find the right bond with enzymes the reaction is much faster and happens almost instantly
 * 9) Explain how you think an enzyme might speed up a reaction.
 * 10) I think an enzyme might speed up a reaction because molecules are attracted to enzymes so they find the right position easily (lowers activation energy)
 * 11) Explain why you think enzymes are so particular about reactions.
 * 12) Enzymes are so particular about reactions because each enzyme can only do a specific job. Kinda like how a puzzle piece only fits perfectly with a few other puzzle pieces
 * 13) How is the shape of an enzyme important?
 * 14) The shape of an enzyme is important because the shape determines what reactions it helps
 * 15) Explain how you know an enzyme is reusable.
 * 16) Because they move through an enzyme and make a chain (catalase- catalase help reaction but aren’t part of it)
 * 17) How does heating an enzyme affect its function?
 * 18) It changes its shape and it cannot react with molecules
 * 19) Does heating an enzyme always have the same effect when the catalyst needs to act on a substance? Explain.
 * 20) yes because it changes the structure forever
 * 1) Explain the difference between hydrolysis and condensation (dehydration).
 * 2) Hydrolysis weakens the bond and releases water and condensation strengthens the bond and gains water
 * 3) Which molecules from our labs undergo these reactions?
 * 4) All of them
 * 1) What are proteins made of?
 * 2) Amino acids
 * 3) What chemical process creates the proteins?
 * 4) Condensation reaction
 * 5) Describe how proteins are made in detail. Sketch a picture.
 * 1) Describe step by step how your body breaks down carbohydrates. Make sure to specify the function of each organ during the steps.
 * 2) 1st enzymes in the mouth and small intestine break down carbohydrates to make glucose, 2nd the stomach secretes acids and starts digestion
 * 3) 3rd carbohydrates are broken down into glucose in the small intestine and then absorbed in the bloodstream
 * 4) When the pancreas detects an incerease in glucose in the bloodstream it pumps insulin
 * 5) Insulin opens the glucose channels and the glucose enters the fat or muscle cell
 * 1) How is fat digested? How is this different from carbohydrates? Be sure to discuss the organs, substances, and enzyme responsible.
 * 2) Bile from the liver and uses emulsification to digest it this is different fat can not be broken down by water and can not be broken down by enzymes so bile molecules have to separate the water and lipid in order to digest it.
 * 1) How do heart attacks occur?
 * 2) When blood flow to a section of the heart is blocked and becomes damaged from lack of oxygen and begins to die

Describe in your own words using any of the images from the above link and draw a picture that describes proteins (do not copy and paste from images):

=Photosynthesis Webquest=

1. What is photosynthesis? The process in which plant cells capture energy from the sun and carbon dioxide and converts it into glucose to use as food.

2. What types of organisms carry out photosynthesis? List 3 groups. Bacteria, plants and algae

3. What is the chemical equation for photosynthesis? What is the translation for the chemical equation? 6CO2 + 6H2O ---> C6 H12 O6 + 6O2 Six carbon molecules twelve hydrogen molecules six oxygen molecules and 6 oxygen2 molecules are created when you add 6 water molecules to 6 carbon dioxide molecules

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? phosphoglyceraldehyde c. 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? Chlorplast inside leaf cells b. What specific cells are involved? mesophyll in the leaf c. What specific organelle is involved? chloroplast

6. How does the plant get the raw materials needed for photosynthesis to the plant part where photosynthesis occurs? water comes up through 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? A stoma is a pore it exchanges oxygen (waste gas) for carbon dioxide (needed for photosynthesis)

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? Chlorphyl is found inside the chloroplast and it is a pigment that captures energy from the sun

9. What is the first part of photosynthesis called and where does it occur? The light stage and it occurs in the thylakoid membrane of the chloroplast

10. What exactly happens in the first part of photosynthesis? The creation of ATP NADPH

11. What is the second part of photosynthesis called and where does it happen? Calvin Cycle in the stroma 12. What happens in the second part of photosynthesis? The plant uses the energy from part one to create PGAL

13. Are the two parts of photosynthesis connected? If so, explain the connection. Yes because in order for the second part to happen the first part has to happen without the energy gathered from part one the plant would not have energy to create PGAL in part two

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 because it doesn’t explain how the water is used and when and where it is used

=Yeast Lab= Our solution was 10% and the ending circumference of our balloon was 23 cm.

Analysis: 1. State 2 clear, concise conclusions derived from the analysis of the results from the experiments in your class. The more sugar solution used the more carbon dioxide the yeast gives off and you can capture the carbon dioxide the yeast gives off in a balloon

2. What was the dependent and independent variables in the experiment? Explain. The dependent variable is carbon dioxide give off and the independent variable is sugar. The yeast depended on the sugar solution, which we changed as our variable

3. According to the experimental data, what kind of environment do yeast prefer? How did the sugar concentration change the result? Explain. The more sugar the more fuel the yeast had to make the bread rise 5. What kind of respiration did the yeast carry out in the experiment? Explain. Alcoholic fermentation because ethanol and CO2 was created

My bread before sitting by window then after 5 minutes then after 2 class periods after baking

my groups balloon test

Why? group 3%

Thugs4Life group 5 %

=DNA replication model=

In DNA replication the DNA splits then the right side gets a new matching left side while the left side gets a new matching right side. In the end you end up with two DNAs. The hydrogen bases know where to go because they only have one job and that is to bond with the matching base. =Cell Portfolio=
