Explanation:
During cellular respiration, OXYGEN serves as an electron acceptor and Adenosine triphosphate (ATP) is produced. during photosynthesis, WATER serves as an electron donor and oxygen molecules, hydrogen ions and electrons are produced.
Answer:
The remaining ADP is at lower energy state.
Explanation:
ATP contain three phisphate bond. These phosphate groups form phosphodiester bond. Hydrolysis of each phosphate bond release about 7.3 Kcal of energy and one ADP. Now this ADP contain only one bond between phosphate group.
Result:
It is clered from the discussion that ADP is at lower energy level as compared to ATP due to less bond between phosphate group.
