Aerobic cellular respiration requires oxygen.
The reactants and products of aerobic cellular respiration can be summarised using a word equation.
Aerobic cellular respiration takes place in the mitochondria and cytoplasm of animal, plant and fungi cells.
Cells that require more energy, because they do a lot of work, have more mitochondria.

Aerobic cellular respiration is a single chemical reaction.

This lesson uses the terms 'chemical process' and 'series of chemical reactions'.

Aerobic cellular respiration - Aerobic cellular respiration is a chemical process that uses oxygen from the air and glucose to provide energy for life processes.
Oxygen - Oxygen is an element found in the air that is a gas at room temperature and a reactant in aerobic cellular respiration.
Carbon dioxide - Carbon dioxide is a compound made of carbon and oxygen that is a gas at room temperature and a product of aerobic cellular respiration.
Mitochondria - Mitochondria are subcellular structures that use glucose and oxygen to carry out aerobic cellular respiration.
Cytoplasm - Cytoplasm is the jelly-like substance inside a cell where its chemical reactions take place.
