Document Summary

Metabolic pathways harvest energy from high energy molecules like glucose (most common source of chemical energy used by organisms) What happens when glucose is oxidized? the glucose in cells is oxidized through a long series of carefully controlled redox reactions. Respiration, like burning, resulting in the complete oxidation of glucose into co2 and water. Fermentation, on the other hand, does not fully oxidize glucose. Cellular respiration releases more energy from glucose than fermentation. The complete oxidation of glucose via cellular respiration can be thought of as a four step process used to convert the chemical energy in glucose to chemical energy in atp. Each of the four steps consists of a series of chemical reactions, and each step has a distinctive starting molecule and a characteristic set of products. Glycolsis: one 6 carbon molecules of glucose is broken is two molecules of the three carbon compound pyruvate. During this process, atp is produced from adp, and nad+.

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.

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.
