Solution

The correct option is A Both the statements A and B are correct.
Photorespiration is a cyclic process in which the enzyme Rubisco acts as an oxygenase enzyme instead of carboxylase enzyme. The active site of this enzyme is same for both of these activities. In C3 plants, some O2 always binds to Rubisco.
Photorespiration does not produce energy or reducing power, rather it consumes energy.
Thus, the correct answer is option A.
