Cellular Respiration
The processes of aerobic cellular respiration and photosynthesis are often called mirror processes. The reactions are exact opposites of each other.
Take a look at both of the equations.
Aerobic Cellular Respiration Photosynthesis
C6H12O6 + 6O2 → 6CO2 + 6H2O + 36ATP 6CO2 + 6H2O → C6H12O6 + 6O2
You will notice that the reactants in aerobic cellular respiration are the products in photosynthesis. Likewise, the reactants in photosynthesis are the products in aerobic cellular respiration. Furthermore, where food is produced in photosyntheis (glucose - C6H12O6 ), it is consumed in cellular respiration. Energy is stored in photosynthesis and is released in cellular respiration.

Energy Currency
You will view a video clip prior to completing this assignment. Create an entry in you journal titled "The Energy Currency".
Write the following notes in your journal.
1. Energy comes from ATP. ATP stands for adenosine triphosphate.
2. Energy is released when a phosphate is removed from ATP. ATP - ADP ADP stands for adenosine diphosphate.
3. Energy is released to build, to repair, to grow, to move and to transport.
4. Energy is stored in the bonds of carbohydrates, proteins, and lipids. To release the energy, the bonds are broken.
5. Released food energy is temporarily stored in a bond that adds a third phosphate to ADP.
ADP - ATP.
6. This cycle repeats over and over again.
Answer the following questions using complete sentences, and create and complete the data chart that follows.
1. How many phosphate groups are in one ATP molecule?
2. What happens when a phosphate group is broken?
3. To what does ATP turn into when one of its phosphates is lost?
4. Briefly explain the ATP – ADP cycle.

Fermentation Lab
Fermentation is the process of changing food, in this case sugar, into a usable form of energy. Fermentation is an anaerobic process meaning it can only occur when oxygen is not present. The fermentation by yeast isimportant to the manufacture of bread, beer, and wine. Baker’s yeast,Saccharomyces cerevisiae, participates in alcoholic fermentation underanaerobic conditions and the gas carbon dioxide is a by product of thisprocess. What substances and conditions promote fermentation by yeast? In this investigation, you will examine the effects of two substances on the rate at which yeast cells perform fermentation.
Instructions: Create an entry in your journal titled “The Fermentation Lab”. Complete the following:
How does the amount of sugar affect the rate of fermentation by yeast?
Hypothesis
Create a hypothesis based on the problem above as an if - then statement.
Procedure
Instructions: Create an entry in your journal titled “The Fermentation Lab”. Complete the following:
- Record the problem.
- Create and record your group’s hypothesis.
- Complete the procedure.
- Create and complete the data table.
- Answer the analysis and conclusions questions using complete statements.
How does the amount of sugar affect the rate of fermentation by yeast?
Hypothesis
Create a hypothesis based on the problem above as an if - then statement.
Procedure
- Obtain the 3 plastic bottles. Label the bottles A, B, and C.
- Add 5 mL of sugar to bottle A.
- Add 30 mL of sugar to bottles B and C.
- Add 2mL of dry powdered yeast to bottles A and B.
- Write the amounts of sugar and yeast added to the bottles on the respective labels.
- Fill bottles A, B, and C about two-thirds full with warm water and quickly place a balloon over the opening of the bottle. Make sure that the balloon fits tightly around the neck of the bottle. Tape the mouth of the ballon to the neck of the bottle. Mix dry ingredients and the water by swirling the bottle gently.
- Place the bottles in a warm spot away from drafts. Carefully observe the bottles today and tomorrow and record your observations in the data table below.
Analysis and Conclusions - Answer in complete statements.
- Identify the independent and dependent variables in this experiment.
- Describe what happened to the balloons A, B, and C.
- Explain why you think this happened.
- Describe how the contents of the bottles with the inflated balloons differ from those with balloons did not inflate.
- Describe how sugar is related to fermentation.
- Explain if your hypothesis was proven correct or not.
