ATP ADENOSINE TRIPHOSPHATE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How is energy stored in ATP?
A
By recharging the ATP
B
By converting the ADP back into ATP through forming a new bond between the 2nd and 3rd phosphate group
C
By converting the ATP back into ADP through forming a new bond between the 2nd and 3rd phosphate group
D
By converting the ADP back into ATP through forming a new bond between the 1st and 2nd phosphate group
Explanation: 

Detailed explanation-1: -This occurs when a molecule of adenosine diphosphate (ADP ) uses the energy released during cellular respiration to bond with a third phosphate group, becoming a molecule of ATP. So the energy from cellular respiration is stored in the bond between the 2nd and 3rd phosphate groups of ATP.

Detailed explanation-2: -When the cell has extra energy (gained from breaking down food that has been consumed or, in the case of plants, made via photosynthesis), it stores that energy by reattaching a free phosphate molecule to ADP, turning it back into ATP. The ATP molecule is just like a rechargeable battery.

Detailed explanation-3: -ATP is made via a process called cellular respiration that occurs in the mitochondria of a cell. Mitochondria are tiny subunits within a cell that specialize in extracting energy from the foods we eat and converting it into ATP.
