The Molecule That Represents Stored Chemical Energy in the Cell

Question

The molecule that represents stored chemical energy in the cell is
A) DNA
B) ATP
C) RNA
D) glucose
E) acetyl CoA

Accepted Answer

ATP (adenosine triphosphate) is the molecule that represents stored chemical energy in the cell. It is often referred to as the "energy currency" of the cell because it is used to power many cellular processes. When ATP is hydrolyzed to ADP (adenosine diphosphate) and Pi (inorganic phosphate), energy is released that can be used by the cell to drive reactions. DNA, RNA, glucose, and acetyl CoA are important molecules in the cell, but they do not represent stored chemical energy in the same way that ATP does.
