Answer : c
Hints & Solution
(c) 2 ATP are required during conversion of PGA to 1,3-diphosphoglyceric acid and 3-phosphoglycerate 1 ATP during conversion of glyceraldehyde-3-phosphate to ribulose-1,5-bisphosphate. 2 NADH molecules are utilised for converting 1,3-diphosphoglyceric acid to glyceraldehyde-3-phosphate.
