The answer is A. ATP I believe because ATP is energy and cells need energy to function so if their is no energy in the blood then the organ or organism wouldn't function properly. Hope this helped you out.
Answer:
1. ATP
Explanation:
An indispensable molecule for the functioning of our organs is ATP. ATP is universally found in living systems. Its essential function is to store energy for the basic vital activities of cells that ensure organ functionality.
Structurally, ATP consists of three phosphate groups (PO 43-) and an adenosine unit composed of adenine and ribose sugar. ATP releases a large amount of usable energy when it is deployed by the addition of a water molecule (hydrolysis).
When the terminal phosphate group is hydrolyzed, and thus removed, the modified molecule is called adenosine phosphate (ADP). This reaction releases energy to the cells that allow the organs to function.
