Which of the following factors assists in avoiding futile cycling of carbohydrates?
A)CO₂ fixation by Calvin cycle procession in the dark
B)citric acid cycle,glycolysis,and oxidative phosphorylation inactivation during the light
C)inhibition of the enzymes of the Calvin cycle by light reactions
D)the absence of glycolytic and citric acid cycle enzymes in plants

Question

Quizplus · Accepted Answer

The correct factor that assists in avoiding futile cycling of carbohydrates is the inactivation of the citric acid cycle, glycolysis, and oxidative phosphorylation during the light. This prevents the simultaneous operation of biosynthetic and degradative pathways, which would otherwise lead to a wasteful consumption of energy.
