Question

quiz 6: cellular respiration quiz
when cells break down food molecules, energy
o is released all at once
o is released entirely as body heat into the environment
o is temporarily stored in atp molecules and released as needed
o causes excitation of electrons in chlorophyll molecules

Explanation:

Cellular respiration breaks down food molecules. Energy from this process is temporarily stored in ATP (adenosine - triphosphate) molecules and released when the cell needs it for various functions. It's not released all at once as it would be wasteful and could damage the cell. Not all energy is released as heat, and excitation of electrons in chlorophyll is related to photosynthesis, not cellular respiration.

Answer:

is temporarily stored in ATP molecules and released as needed
