What is ATP?
A
A molecule that releases energy when broken down
B
A molecule that uses up energy when broken down
C
A molecule that is used up in respiration
D
A molecule that only plants make
Explanation: 

Detailed explanation-1: -adenosine triphosphate (ATP), energy-carrying molecule found in the cells of all living things. ATP captures chemical energy obtained from the breakdown of food molecules and releases it to fuel other cellular processes.

Detailed explanation-2: -Through metabolic processes, ATP becomes hydrolyzed into ADP, or further to AMP, and free inorganic phosphate groups. The process of ATP hydrolysis to ADP is energetically favorable, yielding Gibbs-free energy of-7.3 cal/mol.[1] ATP must continuously undergo replenishment to fuel the ever-working cell.

Detailed explanation-3: -Adenosine 5′-triphosphate, abbreviated ATP and usually expressed without the 5′-, is an important “energy molecule” found in all life forms. Specifically, it is a coenzyme that works with enzymes such as ATP triphosphatase to transfer energy to cells by releasing its phosphate groups.

Detailed explanation-4: -The hydrolysis of ATP breaks the bond between the two outer phosphate groups. This releases the outermost phosphate group along with the free energy that was stored in this bond to produce a molecule of adenosine diphosphate, often shortened to ADP.
