0.7

Question 13

RQ of Proteins?

Answer 13

0.9

Question 14

Atp utilization procedure.

Answer 14

Jab cell mai oxidation hota hai tab RS ki saari energy cell mai ek baar mai energy release nhi hoti atteast in muttiple steps (controlled by enzymes). Iske baad ye chemical energy ke form mai trap no jati hai ie. ATP

This ATP is then utilized only in times of need. otherwise it is stored.
