Photorespiration is _____.
A)a process that rarely occurs in photosynthetic organisms
B)a process involving addition of oxygen to ribulose-1,5-bisphosphate and the formation of ribose-1,5-diphosphate
C)a process involving the addition of oxygen to ribulose-1,5-bisphosphate and the formation of the products 3-phosphoglycerate and 2-phosphoglycolate
D)a process involving the carboxylation of ribulose-1,5-bisphosphate

Question

Quizplus · Accepted Answer

Photorespiration is a process that occurs in some photosynthetic organisms when the concentration of carbon dioxide is low, such as in hot and dry conditions. It results in the addition of oxygen to ribulose-1,5-bisphosphate, which leads to the formation of the products 3-phosphoglycerate and 2-phosphoglycolate. This process reduces the efficiency of photosynthesis and wastes energy, making it an undesirable process for plants.
