Which term describes a molecule that organisms can use to release energy?
Correct Answer:
Energy storage molecule
Explanation:
Energy in biology is stored in chemical bonds within molecules that organisms can tap to do work. The best term is energy storage molecule because it names a molecule that holds usable energy and can release it during metabolism to power cellular processes. Energy is a property, not a substance; a molecule is a general term and doesn’t specify the role of storing or releasing energy; change has no relevance to describing a molecule that provides energy. Classic examples include ATP, which stores energy in its phosphate bonds and releases it when a phosphate group is removed, and glucose, which stores chemical energy that is released when it is oxidized.
