Final answer:
Cells use ATP molecules to harness the potential energy stored in glucose to do work for the cell.
Step-by-step explanation:
Cells use ATP molecules to harness the potential energy stored in glucose. When glucose is broken down through cellular respiration, the energy stored in its chemical bonds is released and used to make ATP. ATP acts as an energy currency in the cell, powering various chemical reactions and processes. This process allows cells to perform work such as building complex molecules, transporting materials, and powering movement.
