Protista/Fungi/Cell Respiration Remediation Guide
Short Answer
1. What is cellular respiration?
2. List the three main stages of cellular respiration in order. Where does each stage take place in the cell?
3. Cellular respiration is able to extract about 38 percent of the potential energy from glucose. What happens to
the rest of the energy? Give an example.
4. What happens during glycolysis?
5. Describe glycolysis in terms of energy input, energy output, and net gain of ATP.
6. Give two examples of fermentation.
Figure 9–1
7. Based on Figure 9–1, which type of fermentation does NOT give off carbon dioxide? Explain your answer.
8. Identify 5 characteristics of Protists. Give 3 examples of protists.
9. Identify 5 characteristics of Fungi. List 3 example organisms.

SHORT ANSWER
1. ANS:
Cellular respiration is the process that releases energy by breaking down food molecules in the presence of
oxygen.

2. ANS:
The three stages are as follows: glycolysis (which occurs in the cytoplasm), the Krebs cycle (which occurs in
the mitochondria), and electron transport (which occurs in the mitochondria).

3. ANS:
The rest of the energy is released as heat, as indicated by the fact that you feel warmer after exercising and are
able to maintain a constant temperature even in cold weather.

4. ANS:
During glycolysis one molecule of glucose is broken in half, producing two molecules of pyruvic acid.
