Anaerobic Respiration Sometimes cells experience conditions with little or no oxygen There are several consequences when there is not enough oxygen available for respiration: There is no final acce...
Practical: Investigating the Rate of Respiration Respirometers are used to measure and investigate the rate of oxygen consumption during aerobic respiration in organisms The experiments usually inv...
Oxidative Phosphorylation Oxidative phosphorylation is the last stage of aerobic respiration It takes place at the inner mitochondrial membrane It results in the production of many molecules of ATP...
Link Reaction The end product of glycolysis is pyruvate Pyruvate contains a substantial amount of chemical energy that can be further utilised in respiration to produce more ATP The enzymes and coe...
