Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which has more energy?
A
ATP
B
ADP + Pi
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -ATP (adenosine triphosphate) stores more energy than ADP (adenosine diphosphate). ATP has three phosphate groups with high energy bonds located between each group. ADP has only two phosphate groups.

Detailed explanation-2: -ADP contains more potential energy than ATP. Following hydrolysis, ATP can give off one phosphate group and usable energy, whereas ADP cannot. The energy produced by ATP comes from the breaking of the bond between two phosphate groups.

Detailed explanation-3: -The breakdown of one glucose molecule is enough to make around 38 molecules of ATP. So, clearly, glucose has a lot more stored energy than ATP does.

Detailed explanation-4: -ATP (Adenosine Triphosphate) contains high energy bonds located between each phosphate group. These bonds are known as phosphoric anhydride bonds.

Detailed explanation-5: -During cellular respiration, the energy formed in mitochondria is stored in the form of ATP which is also known as energy currency of the cell. It provides energy for all the life activities by its breakdown into ADP and Pi. ATP contains three phosphate group which has high energy bond.
