Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The energy provided by ATP comes from what?
A
Adenosine
B
The phosphate groups
C
The bonds between the phosphate groups
D
The excited electron
Explanation: 

Detailed explanation-1: -ATP is an excellent energy storage molecule to use as “currency” due to the phosphate groups that link through phosphodiester bonds. These bonds are high energy because of the associated electronegative charges exerting a repelling force between the phosphate groups.

Detailed explanation-2: -ATP is a nucleotide consisting of an adenine base attached to a ribose sugar, which is attached to three phosphate groups. These three phosphate groups are linked to one another by two high-energy bonds called phosphoanhydride bonds.

Detailed explanation-3: -It is the creation of ATP from ADP using energy from sunlight, and occurs during photosynthesis. ATP is also formed from the process of cellular respiration in the mitochondria of a cell. This can be through aerobic respiration, which requires oxygen, or anaerobic respiration, which does not.

Detailed explanation-4: -The bonds between phosphate molecules are called phosphoanhydride bonds. They are energy-rich and contain a
