When one CO2 molecule is fixed as one molecule of triose phosphate, which of the following photochemically made, high energy chemical intermediates are used in the reduction phase?
- A2 ATP + 2 NADPH
- B1 ATP + 1 NADPH
- C1 ATP + 2 NADPH
- D2 ATP + 1 NADPH
View written solutionFree
Correct answer: A
The reduction step of Calvin cycle involves utilisation of two molecules of ATP for phosphorylation and two molecules of NADPH for reduction per molecule of CO2 fixed.
