Final answer:
The chemical energy from glucose is released and transferred to ATP molecules, which serve as the cellular energy currency.
Step-by-step explanation:
In order to perform cellular work, the chemical energy from glucose must be released and transferred into ATP (adenosine triphosphate) molecules. Glucose, with the chemical formula C6H12O6, is a simple sugar that when broken down through cellular respiration, releases energy.
This energy is then used to synthesize ATP, which acts as the energy currency of the cell, carrying energy to wherever it is needed within the cell.
