During which process is G3P removed from the Calvin cycle to be used in the production of carbohydrates?

A. photosynthesis

B. carbon fixation

C. reduction

D. regeneration

The answer is D. regeneration

The Calvin Cycle is characteristic for photosynthetic organisms. It consists of three phases - carbon fixation, reduction, and regeneration. In the second phase, reduction, 3-phosphoglyceric acid (PGA) is reduced to glyceraldechide-3-phosphate. Further, in the third phase, regeneration, some of G3P are removed from the Calvin Cycle to be converted to glucose and other carbohydrates.
