Cellular respiration is a process by which cells use organic compounds such as glucose in presence of oxygen to generate energy in the form of ATP, that is used to drive cellular processes such as transport.
Cellular respiration generates ATP together with carbon dioxide and water as by products.
The process mainly takes place in the mitochondria also known as the power house of the cell. The process occurs in three stages, namely; glycolysis, Kreb's cycle and electron transport chain.
