Word and balanced symbol equations for anaerobic cellular respiration in humans, and conditions in which it occurs
Word and symbol equations for anaerobic respiration in plants and micro-organisms, and conditions in which it occurs
Anaerobic cellular respiration takes place only in the cell cytoplasm and does not involve mitochondria
Anaerobic cellular respiration provides less ATP (so less energy) than aerobic cellular respiration, but more quickly
Uses of anaerobic cellular respiration (fermentation) in yeast

Students sometimes think that plants don't respire, and that they (only) photosynthesise instead.

This lesson contains examples of plants respiring.

Cellular respiration - An exothermic chemical process that transfers energy for life processes, using glucose as a fuel.
Anaerobic - A process that does not require oxygen.
Lactic acid - A product of anaerobic cellular respiration in humans that causes muscle cramps.
Oxygen debt - The amount of oxygen necessary to remove lactic acid from the body after exercise.
Fermentation - Anaerobic cellular respiration in yeast that produces ethanol (a type of alcohol) and carbon dioxide gas.
