Answer 7

Inter converts GA-3-P and dihydroxyacetone-P

Question 8

Glyceraldehyde-3- phosphate dehydrogenase

Answer 8

Oxidizes GA-3-P to 1,3-diphosphoglycerate using NAD+ and Pi, to form, NADP and H+

Question 9

Phosphoglycerokinase

Answer 9

Generates ATP from ADP

Question 10

Phosphoglyceromutase

Answer 10

Uses 2,3-diphosphoglycerate to convert 3-phosphoglycerate to 2-phosphoglycerate

Question 11
