5. Cellular Respiration

1. Core Content

Cellular Respiration

• The process of respiration and uses of energy for living cells:

- aerobic respiration: in cytoplasm and mitochondria; use words and symbols: glycolysis, Krebs cycle and oxidative phosphorylation (no biochemical detail is required);

- anaerobic respiration: production of lactic acid in muscles during exercise; words and symbols (no biochemical detail of process is required);

- The role of anaerobic respiration in the industry, e.g beer brewing and bread making.

• A comparison between aerobic respiration and anaerobic respiration in terms of raw materials required, products and relative amounts of energy released.
