The loss of carbon fixing activity of the enzyme RuBP carboxylase is directly proportional to
A)high temperatures and high light intensities.
B)low temperature and low light intensities.
C)completely dark conditions.
D)lack of carbon dioxide.
E)lack of oxygen.

Question

Quizplus · Accepted Answer

High temperatures and high light intensities increase the rate of photorespiration, which competes with carbon fixation by RuBP carboxylase, reducing its efficiency.
