Which process involves gas exchange between the atmosphere and the cells of the body and the resulting chemical reactions that provide the cells with energy to function.
respiration

breathing
The Correct Answer is A
A. Respiration: Respiration encompasses gas exchange (external/internal) and cellular reactions (cellular respiration) that produce energy
B. Oxidation: Oxidation is a chemical process involved in metabolism but does not by itself describe the full gas-exchange-energy sequence
C. Metabolism: Metabolism is the sum of biochemical reactions (including energy production) but doesn’t explicitly include atmospheric gas exchange -less precise / incorrect for the combined description.
D. Breathing: Breathing (ventilation) is the mechanical movement of air and does not include cellular chemical reactions that generate cellular energy
