Q

describe the reduction of phosphoglyceric acid

A
  1. phosphoglyceric acid is phosphorylated to from 1,3 biphosphoglycerate
  2. 1,3 biphosphoglycerate is reduced by electrons from NADPH to form trios phosphate

Q

describe carbon dioxide fixation

A

carbon dioxide diffuses through stomata into chloroplast, where it combines with ribulose biphosphate to form phosphoglyceric acid.
