Final answer:
Cells transform chemical energy into ATP, which is then used to power various cellular processes essential for life, including movement and function.
Step-by-step explanation:
The chemical change that allows cells to move and function is the transformation of chemical energy stored in molecules like sugars and fats into ATP (adenosine triphosphate). This process is a part of cellular metabolism, which involves both anabolic and catabolic reactions.
During this energy transformation, the energy within ATP becomes readily accessible for the cell to perform various tasks. These tasks include building complex molecules, transporting materials, powering the motion of structures like cilia and flagella, and contracting muscle fibers to create movement.
These cellular processes are critical to maintaining life functions and responding to environmental cues, demonstrating a close coupling between cells and their surroundings.
