Question

Which of the following processes occurs during the second phase, the reduction phase, of the Calvin cycle?

Carbon fixation
-ATP production
-RuBP (ribulose bisphosphate) regeneration
-NADPH production
-Molecular oxygen production
-G3P production

Answer 1

During the reduction phase of the Calvin cycle, ATP and NADPH are produced, and glyceraldehyde 3-phosphate (G3P) is produced from 3-phosphoglycerate (3-PGA).

Step-by-step explanation:

During the second phase, the reduction phase, of the Calvin cycle, the following processes occur:

1. ATP production: Six molecules of ATP are used to convert 3-phosphoglycerate (3-PGA) into glyceraldehyde 3-phosphate (G3P).
2. NADPH production: Six molecules of NADPH (from the light-dependent reactions) are used to convert 3-PGA into G3P.
3. G3P production: The reduction of 3-PGA using ATP and NADPH results in the production of G3P, which can be used to synthesize glucose.
