1 answer

In the reduction phase of the Calvin cycle, each molecule of 3-phosphoglycerate (3-PGA) is reduced to glyceraldehyde-3-phosphate (G3P) using energy in the form of ATP and reducing power in the form of NADPH.

Specifically:

  • ATP provides the necessary energy for the conversion of 3-PGA to G3P.
  • NADPH donates electrons, acting as a reducing agent in the reduction of 3-PGA to G3P.

These molecules are generated during the light-dependent reactions of photosynthesis.
