Which of the following statements summarizes the metabolic results of photorespiration?
A) It produces ATP and consumes oxygen and carbon dioxide.
B) It produces carbon dioxide and consumes ATP and oxygen.
C) It produces oxygen and consumes ATP and carbon dioxide.
D) It produces oxygen and ATP and consumes carbon dioxide.

Question

Quizplus · Accepted Answer

Photorespiration produces carbon dioxide and consumes ATP and oxygen. During photorespiration, rubisco enzyme fixes oxygen instead of carbon dioxide, resulting in the production of a toxic compound, which is then broken down into carbon dioxide in a series of reactions. This process consumes ATP and releases carbon dioxide, resulting in a loss of fixed carbon. Photorespiration can be considered as a wasteful process for the plant as it results in the loss of carbon that could have been used for growth and other metabolic processes.
