Photorespiration is
A) not a problem, because oxygen is not available in the chloroplast where photorespiration takes place.
B) a process involving the carboxylation of ribulose- 1,5- bisphosphate.
C) a process involving addition of oxygen to ribulose- 1,5- bisphosphate and the formation of ribose- 1,5- diphosphate.
D) a process involving the addition of oxygen to ribulose- 1,5- bisphosphate and the formation of the products 3- phosphoglycerate and 2- phosphoglycolate.

Question

Quizplus · Accepted Answer

Photorespiration is a process in which oxygen is added to ribulose- 1,5- bisphosphate leading to the formation of the products 3- phosphoglycerate and 2- phosphoglycolate. This process occurs in the chloroplasts and mitochondria of plants and is considered a wasteful process as it reduces the efficiency of photosynthesis.
