Answer;
C) It stores energy that comes from glucose.
Explanation;
-ATP is a biomolecule that is a product of cellular respiration which is used as a store of energy and is the usable form of energy by the cell.
-ATPs are used as the main energy source for metabolic functions. They are consumed by energy-requiring (endothermic) processes and produced by energy-releasing (exothermic) processes in the cell.
-ATP is able to store and transport chemical energy within cells. Energy is released by hydrolysis of the third phosphate group.
