=My Organism= This organism lives in many different parts of the world. It can go under water and also sling webs to help it crawl things such as trees. It eats fish, flies, and other types of bugs. It is poisoness to the human touch.

=Catalase Chart:= If a catalase is the enzyme found in most plant and animal cells that decomposes hydrogen peroxide into oxygen and water, then why did the milk, the egg yolk and the peas all have the same numbers when one is a vegetable one is a meat and one is milk?

They all have a high capacity to hold in water. The outer layers of the pea, help to hold in oxygen and water. Also, the layers of the egg yolk, do the same as the outer shell of the pea. ( http://biology.clc.uc.edu/Courses/bio104/lipids.htm ) Milk also hold in high amounts of water and oxygen. Study's show that milk is the ideal sports drink because, it hydrates and regenerates the human body. ( http://www.seattlepi.com/health/327196_condor13.html )

=Biomolecule Lab=

=WEB QUEST= A.) 1. Explain how heat affects the rate of reaction. - when you raise the heat, it causes the energy level to raise up. 2. Explain how surface area affects the rate of reaction. - if one reactant is a solid, the surface area of the solid will cause the speed of the reaction to change. the larger the surface area, the faster the reaction takes place. 3. Explain how concentration affects the rate of reaction. - the higher the concentration, the more frequent the reactions are.

B.) 1. What types of molecules make up enzymes? - they are mostly proteins but they catalyze. they are composed of hundreds of amino acids. 2. What determines the function of an enzyme? - it binds reactants together, in a reaction. 3. What is denaturing? - it means to modify which can be done by heating it up, adding acid alkali or radiation which removes or diminishes the original properties. 4. Describe how a reaction takes place without an enzyme and then with an enzyme. - a reaction without an enzyme will take longer than it would if it contained enzymes because, it takes more energy. a reaction with an enzyme decreases the amount of energy that is released and the reaction takes a shorter amount of time. 5. Explain how you think an enzyme might speed up a reaction. - because, they are lower concentrated. 6. Explain why you think enzymes are so particular about reactions. - because, they have intricate structure. 7. How is the shape of an enzyme important? - because, they are shape made. they only can react with other enzymes of the same shape. 8. Explain how you know an enzyme is reusable. - they are reusable because, they are a catalysts and a catalyst can be used without being destroyed, thus proving that an enzyme can be reused. 9. How does heating an enzyme affect its function? - it has a negative affect on it. 10. Does heating an enzyme always have the same effect when the catalyst needs to act on a substance? Explain.

C.) 1. Explain the difference between hydrolysis and condensation (dehydration). - condensation makes polymers and hydrolysis breaks them down.

2. Which molecules from our labs undergo these reactions?

D.) 1. What are proteins made of? - amino acids

2. What chemical process creates the proteins? - protein synthesis

3. Describe how proteins are made in detail. Sketch a picture.

E.) 1. Describe, step by step how your body breaks down carbohydrates. Make sure to specify the function of each organ during the steps.

F.) 1. How is fat digested? How is this different from carbohydrates? Be sure to discuss the organs, substances, and enzymes responsible.

G.) How do heart attacks occur? - when blood flow to the heart is severely reduced or stopped.

H.) Describe in your own words using any images from link and draw a picture that describes proteins. 1. Primary structure 2. Secondary structure 3. Tetiary structure 4. Quartemary structure

=Light Intensity Lab=

- Wavelength is the color of light. The maximum light intensity is 200. You need as much light intensity a you can get. You would need a wavelength of 425. Because, with that combination, the plant can produce it's optimal amount of ATP.
 * Discussion of wavelength and light intensity amount needed to create maximum ATP**

- The higher the amount of light intensity the more photosynthesis that occurs. It uses energy from sunlight to conduct photosynthesis. When you have a low intensity, photosynthesis is limited. If you have a high amount of light intensity then there is more photosynthesis occurring.
 * Discusses relationship of light intensity to the process of photosynthesis.**

- Color of light, depends on wavelength. So, chlorophyll absorbs all colors of light, except green, which reflects back to your eyes making it look green. So, certain wavelengths would be more affective in photosynthesis.
 * Discusses relationship of wavelength to the process of photosynthesis**

- Green is the pigment of chlorophyll. Certain pigments absorb different colors of light. For example: chlorophyll reflects green light, back to your eyes making it look green.
 * Discussion of how pigment colors are related to photosynthesis and wavelength**

=Photosynthesis Web Quest=

Photosynthesis is considered by many to be the most important process to occur on earth. To learn about photosynthesis, complete the "Photosynthesis Webquest" (Each team member needs to complete the webquest on their own web page). Visit [|www.ftexploring.com] then use the photosynthesis links to answer the following questions.

1. What is photosynthesis? - the process when plants generate carbohydrates, and oxygen from carbon dioxide, water and light energy.

2. What types of organisms carry out photosynthesis? List 3 groups. - plants - cyanobacteria - euglena

3. What is the chemical equation for photosynthesis? What is the translation for the chemical equation? - 6CO2 + 6H2O à C6H12O6 + 6O2 - 6 molecules of water + 6 molecules of carbon dioxide yields on molecule glucose + 6 molecules of oxygen

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? - water and carbon dioxide

b. What are the products of photosynthesis? - Glucose and oxygen

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? - the leaves

b. What specific cells are involved? - mosophyll cell, epidermal cells, stomata cells

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? - by absorbing carbon dioxide through its leaves and it absorbs water through its root system

7. What is a stoma and of what value is the stoma to the plant in its efforts to carry out photosynthesis? - a gel like matrix that surrounds the thylakoid. - The air flows into the air spaces, through the stoma which means that the stoma brings in carbon dioxide in the air which is 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? - Chloroplasts are needed for photosynthesis. The membrane envolope, the inner envolope, stroma, and thalakoids are some of the things, found inside the organelle. The membrane envelope holds chloroplast together and it separates it from the rest of the cell. The inner envelope is the part that controls the flow of materials such as water, and oxygen that go in and out of the chloroplast. The thylakoids of the chloroplast is where the color for the chloroplast comes from.

9. What is the first part of photosynthesis called and where does it occur? - in the thylakoids

10. What exactly happens in the first part of photosynthesis? -

11. What is the second part of photosynthesis called and where does it happen? - Calvin Cycle

12. What happens in the second part of photosynthesis? - production of complex carbohydrates such as glucose that use carbon dioxide and energy that comes from the energy carriers.

13. Are the two parts of photosynthesis connected? If so, explain the connection.

14. Does the chemical equation that you listed in number 3 tell the entire story of the process of photosynthesis? Why or why not?

= **ANALYSIS OF YEAST LAB** =


 * Analysis**:

1. State 2 clear, concise conclusions derived from the analysis of the results from the experiments in your class. - the more yeast that you have, the more carbon dioxide is released thus making the size if your balloon larger. - The more sugar, the more active the yeast is.

2. What was the dependent and independent variables in the experiment? Explain. - dependent ~ yeast ; sugar water - independent ~ the gas that is produced ( how big the balloon got ) - the energy that comes from the yeast and sugar combination

3. According to the experimental data, what kind of environment do yeast prefer? How did the sugar concentration change the result? Explain. - Yeast prefers a warm, moist environment. - The more sugar that we had present, there was more energy produced, to produce more gas.

4. How did the amount of rising change with the different types of sugar solutions used? - the higher the percent of sugar present, it created a higher circumference of the balloon.

5. What kind of respiration did the yeast carry out in the experiment? Explain. - anaerobic, because the yeast doesn’t require oxygen.

Botto =Replication of DNA=

DNA replication is the process where more DNA is made. Each strand of the DNA is doubled in order to create more, DNA. One strand of DNA is split and added to another, to create a new one. DNA replication occurs during the interphase stage of mitosis.
