Question

Which of the following statement is incorrect?

Photorespiration occurs in chloroplasts.
Photorespiration occurs during the daytime.
Photorespiration occurs in C3 plants.
Photorespiration occurs in C4 plants.

hint Hint:

Photorespiration refers to a process in plant metabolism where the enzyme RuBisCO oxygenates RuBP, wasting some of the energy produced by photosynthesis

The correct answer is: Photorespiration occurs in C4 plants.

Photorespiration does not occur in C4 plants. This is because they have a mechanism which increases the CO2 concentration at the site of the enzyme.
