Aerobic and anaerobic respiration, and the importance of energy release.
Respiration
Respiration releases energy from glucose in every cell (not the same as breathing). Energy is used for movement, growth, active transport and keeping warm.
- Aerobic (with oxygen): glucose + oxygen → carbon dioxide + water (+ much energy).
- Anaerobic (without oxygen): in muscles, glucose → lactic acid (+ a little energy). Vigorous exercise causes an oxygen debt repaid by deep breathing afterwards.
