Cambridge IGCSE Biology, topic 12

Respiration

Respiration is the process that releases energy from food in every living cell. This topic covers what living organisms use that energy for, how aerobic and anaerobic respiration differ, the equations for each, and how the body deals with lactic acid after vigorous exercise.

Subtopics
