toc =[|My Blog]= = = =About Me=

Hello. I am in the band in which I play the saxophone and the flute. Which in the fall band is all I do. I'm not just in the band though I play sports such as basketball and softball in which I made the all star team in 2006 for softball. Out of school I going hunting with my dad. I mostly go duck hunting. I will also go goose, deer, and turkey hunting. I am a quiet person and may people say that I'm a perfectionist. Unlike many teens my age I actually enjoy going to school. When I finish high school I would like to go college and become a history teacher or earth science.

=Create an Organism=



Latura leo has an otter's head and a body of a lion. He is a carnivore because he will eat fish and many small mammals such as squirrels. On a daily bases Latura leo will first go out to find food then lay down in the heat of the day in a nice shady place, he will then in the afternoon go for food. He does get into fights due to his lion nature, but not many. Only when he feels threatened. He can be found in the lands of Africa, and North America mostly near water or in a very shady place.

=Catalase Activity=



1. The things that I discovered when I saw all the results for the avocado was how other groups results were very close to what I found. A very surprising discovery was how one group had their results for the room temperature and cool peroxide as a 1 and warm a 2 when many of the groups had 3, 4, and 5s. The only reason that I can think of for that big of a difference in results is groups could have done something wrong to cause that big of difference. The next discovery that I found is the warm peroxide had the higher results then the room temperature and cool. That exempts the results that had a 5 for all three categories. The conclusion that I can make between temperature and enzymes is the higher the temperature the more active the enzyme is. There was presence of catalase in the avocado.

2. The question that I have is what are some factors that can affect the reaction of catalase and the hydrogen peroxide?

http://www.tutorvista.com/ks/effect-of-temperature-on-enzyme-catalase http://www.worthington-biochem.com/introbiochem/effectspH.html

What I found is temperature and ph are major factors of the catalase effectiveness.

=Biomolecules=

Out of five results all five put there was no starch.

Out of five people 20% said there was sugar present.

Out of five people 40% have protein as present.

Out of five people only 20% had fats as present.

What kinds of biomolecules are in each of the food substances you tested? Sugar, and protein.

Do certain biomolecules have the same catalase reactions? Explain. No because different foods will act differently to catalase.

What other results did you observe in the class that can be used to make a statement of what you have learned? Not all the results were the same. 0% didn't see starch, 20% saw fats, 40% saw proteins, and 20% saw simple sugar.

A.


 * 1) Explain how heat affects the rate of reaction.

Heat makes the molecules speed up. The surface area affects how fast the reaction will happen. Makes them multiply. B. Proteins The substraight. When high temperatures or pH changes the molecule shape. Without an enzyme the reaction is the two molecules take longer to connect. With an enzyme the molecules connect in less time. I think the enzyme can speed up a reaction by speeding up the bond process between the molecules. I think enzymes are so particular so they can get the right reaction. If they don’t get the right reaction then something wouldn’t be right. Because the enzymes only react with a certain molecule. It is reusable because it is catalase and it can not be destroyed. The biomolecules can lock in the enzyme because the enzyme has changed shape due to the heat.
 * 1) Explain how surface area affects the rate of reaction.
 * 1) Explain how concentration affects the rate of reaction.
 * 1) What types of molecules make up enzymes?
 * 1) What determines the function of an enzyme?
 * 1) What is denaturing?
 * 1) Describe how a reaction takes place without an enzyme and then with an enzyme.
 * 1) Explain how you think an enzyme might speed up a reaction.
 * 1) Explain why you think enzymes are so particular about reactions.
 * 1) How is the shape of an enzyme important?
 * 1) Explain how you know an enzyme is reusable.
 * 1) How does heating an enzyme affect its function?

10. Does heating an enzyme always have the same effect when the catalyst needs to act on a substance? Explain. Yes because once the enzyme has changed it’s shape it can no longer function properly.

C. Condensation is what builds up the large molecules losses water. Hydrolysis breaks down the large molecules into smaller ones. Adds water. All biomolecules undergo the reactions.
 * 1) Explain the difference between hydrolysis and condensation (dehydration).
 * 1) Which molecules from our labs undergo these reactions?

D. Proteins are made up of amino acids. The process is called condensation. Proteins are made from the 20 amino acids combining together. E. Describe step by step how your body breaks down carbohydrates. Make sure to specify the function of each organ during the steps. Enzymes that are in your mouth and small intestine will help to break them down, gastric juices will secreted in the stomach, the carbs are broken into glucose them absorbed into the bloodstream, the pancrease will pump insulin into the bloodstream the glucose can know go into the muscle cell it is know used for energy.
 * 1) What are proteins made of?
 * 1) What chemical process creates the proteins?
 * 1) Describe how proteins are made in detail. Sketch a picture.

F. How is fat digested? How is this different from carbohydrates? Be sure to discuss the organs, substances, and enzyme responsible. Bile that is stored in the liver and gall bladder will go between the water and fat. This is different than carbs because carbs don’t need bile to be digested. G. How do heart attacks occur? It occurs when the blood flow to the heart is cut off. The heart muscle will be damaged because it does have the oxygen it needs. H. Primary structure- a chain sequence of amino acids Secondary structure- when the sequence of the amino acids are linked by hydrogen bonds Tertiary structure- attraction show between alpha helices and pleated sheets Quartemary structure- consist of at least one amino acid chain.

=DNA replication model= Step 1:__** The DNA strand is twisted. The enzyme DNA helicase will unwind the strand.
 * __[[image:dnastepsmodelrfb.jpg]]


 * __Step 2:__** The DNA strand is completely unwound.


 * __Step 3:__** The DNA strand brakes up due to DNA helicase.


 * __Step 4:__** The adenine (A) connects with thyme (T) and cytosine (C) connects with guanine (G).


 * __Step 5:__** The final step. The right side of the original strand gets a new left and the left side of the original stand gets a new right.

DNA replication happens during the interphase stage of mitosis.


 * __Telomeres-__** Located at the ends of the chromosomes. Keep the ends of the different chromosomes from coming together. Slowly shrink due to mitosis.


 * __Okazaki fragments-__** small section of a DNA strand.


 * __DNA ligase-__** expands the okazaki fragments.


 * __Telomerase-__** enzymes that adds telomeres to the ends of okazaki fragments.
 * __Cancer-__** comes from somatic cells. Produce a high level of telomerase during the cell cycle.


 * __Transplanted cells-__** cells are removed, are transformed from a gene that the person can’t produce, return it back to the person.


 * __Cloning-__** telomeres are not present the first part of the life. When the are present they are very short.


 * __Aging-__** telomeres shorten as you age.
