Cellular Respiration
- cells break down small food molecules, previously assimilated, in order to release stored chemical energy.
- Chemical energy is used for muscle contraction, active transport, building up large molecules and cell division.
- IN AEROBIC RESPIRATION OXYGEN IS USED TO OXIDISE FOOD.
- Carbon dioxide and water are released as waste products.
- RESPIRATION WITHOUT OXYGEN IS ANAEROBIC
- Glucose is not broken down fully and less energy is produced.
- The waste products in yeast cells are ethanol and carbon dioxide.
- Waste products in animal cells is lactic acid.
