Which of the Following Does Photorespiration Do

Question

Which of the following does photorespiration do?
A)generates carbon dioxide and consumes ATP and oxygen
B)generates ATP and sugars and consumes oxygen and carbon dioxide
C)generates oxygen and consumes ATP, carbon dioxide, and sugars
D)consumes carbon dioxide and generates ATP, sugars, and oxygen
E)consumes carbon dioxide and ATP

Accepted Answer

Photorespiration is a process in which oxygen is consumed and carbon dioxide is generated, resulting in a net loss of carbon compounds in plants. This process occurs when rubisco, the enzyme responsible for fixing carbon dioxide, mistakenly binds to oxygen instead. This generates a toxic compound that must be metabolized, resulting in the release of carbon dioxide and consumption of ATP and oxygen. Therefore, the correct option is A.
