photosynthesis

Question 1

what is the site of light independent reaction

Answer 1

stroma

Question 2

what are the three phases of light independent reaction

Answer 2

1. carbon dioxide fixation
2. reduction of PHOSPHOGLYCERIC ACID
3. regeneration of RIBULOSE BIPHOSPHATE

Question 3

describe the reduction of phosphoglyceric acid

Answer 3

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

Question 4

what are the three stages of photosynthesis

Answer 4

light harvesting

light dependent reaction

light independent reaction (co2 fixation, reduction of phosphoglyceric acid, regeneration of ribulose biphosphate)

Question 5

describe carbon dioxide fixation

Answer 5

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

Question 6

site of light dependent reaction

Answer 6

granum
