Encyclopedia > Aerobic respiration
This article or section should be merged with aerobic metabolism.

Aerobic respiration requires oxygen. It is the preferred method of pyruvate breakdown. It consists of two metabolic pathways:

  1. Kreb's cycle
  2. Oxidative phosphorylation

In aerobic respiration, an electron is transferred from an energy-rich atom (such as a carbon atom in an organic molecule) to an oxygen atom, via an electron transport chain. Oxygen serves as the "terminal electron acceptor" in the electron transport chain. In the process, it yields 36 ATP molecules, as well as carbon dioxide, and water. This makes for a total gain of 38 ATP molecules during cellular respiration. This takes place in the mitochondria in eukaryotic cells, and at the cell membrane in prokaryotic cells.

Cellular respiration is the process in which the chemical bonds of energy-rich molecules such as glucose are converted into energy usable for life processes.
Cellular respiration is the same process but it occurs in gradual steps that result in the conversion of the energy stored in glucose to usable chemical energy in the form of ATP.
Respiration is the process by which cells obtain energy when oxygen is present in the cell.
