Questions: 4.2.2 Qulz: Respiration Introduction Question 4 of 10 Why could a loss of chlorophyll limit cellular respiration in plants? A. There would more ATP molecules produced. B. There would be too much carbon dioxide produced. C. There would be less glucose produced for respiration. D. There would be too much oxygen produced. SUBMIT PREVIOUS

The answer is C: There would be less glucose produced for respiration.

Explanation for each option:

A. There would more ATP molecules produced.

• This is incorrect. A loss of chlorophyll would not lead to more ATP production. Chlorophyll is essential for photosynthesis, which produces glucose. Without sufficient glucose, cellular respiration would be limited, reducing ATP production.

B. There would be too much carbon dioxide produced.

• This is incorrect. A loss of chlorophyll would not directly cause an increase in carbon dioxide production. In fact, less photosynthesis would mean less carbon dioxide is used, but it doesn't directly increase its production.

C. There would be less glucose produced for respiration.

• This is correct. Chlorophyll is crucial for photosynthesis, which produces glucose. Without enough chlorophyll, the plant would produce less glucose, limiting the substrate available for cellular respiration.

D. There would be too much oxygen produced.

• This is incorrect. A loss of chlorophyll would actually result in less oxygen production because photosynthesis, which produces oxygen, would be reduced.

Summary: A loss of chlorophyll would limit the plant's ability to perform photosynthesis, resulting in less glucose production, which in turn limits cellular respiration.
