Document Summary

Photosynthesis generates oxygen and organic molecules that are used by the mitochondria of eukaryotes as fuel for cellular respiration. Respiration breaks this fuel down, generating atp. The waste products of this type of respiration, co2 and h2o, are the raw materials for photosynthesis. Organic compounds + oxygen co2 + h2o + energy. Carbohydrates, fats, and protein molecules from food can all be processed and consumed as fuel. Fermentation is a type of catabolic process that is a partial degradation of sugars or other organic fuel that occurs without the use of oxygen (anaerobic). Cellular respiration includes both aerobic and anaerobic processes, but often referred to as the aerobic process. This is also a catabolic process, but it uses oxygen to break down sources of energy. A redox reaction is the transfer of one or more electrons from one reactant to another.

While Jill and Andre were studying for their Biology exam, Andre said, âAnimals perform cellular respiration and plants perform photosynthesis.â What about Andreâs statement should Jill have told him was incomplete?

Animals also perform photosynthesis.

Plants do not perform photosynthesis.

Animals do not perform cellular respiration.

Plants also perform cellular respiration.

There is nothing incomplete about Andreâs statement.

Both respiration and fermentation use organic molecules.

Respiration uses oxygen, fermentation does not.

Question 4

Select one answer.

10 points

Energy is harvested from which reaction to produce ATP?

Carbon dioxide and water â sugar and oxygen.

Sugar and oxygen â carbon dioxide and water.

Question 5

Select one answer.

10 points

What is the source of energy for photosynthesis?

Light

CO2

Water

Sugar

Question 6

Select one answer.

10 points

One way to explain how cellular respiration and photosynthesis relate to each other is to say that:

Plant cells use the oxygen produced by respiration for photosynthesis.

The oxygen produced by photosynthesis, once released to the environment, is the oxygen able to be used as the electron acceptors for cellular respiration.

Cellular respiration is a series of reduction reactions while photosynthesis is a series of oxidation reactions.

The two processes are not related.

The use of oxygen by plants contributes to the greenhouse effect.

1.Aerobic cellular respiration: In the absence of oxygen â what processes stop? Why do they stop?

2. Do the reactions that are unique to fermentation itself (not the reactions of glycolysis that precede the fermentation-specific steps) provide the cell with additional useful high-energy molecules? Explain briefly. If you answered yes â how many high-energy molecules and what kind? If you answered no â then why does the cell do the fermentation step?

3. Do the cells in your body do fermentation? Explain.

4. When cells use fermentation instead of aerobic cellular respiration, is NAD+/NADH involved in this process? What happens to this molecule? Explain briefly.

5. Your body can harness energy from sources besides carbohydrates like glucose. Briefly explain how proteins and fats can be broken down and funneled into the reactions of cellular respiration.
