| TERMS | DEFINITIONS |
| Respiration | The series of oxidation reduction reactions in which substances (glucose) are oxidized to carbon dioxide
and oxygen and energy is releasedis called |
| Aerobic respiration | Aerobic respiration takes place in the presence of free oxygen. It includes Krebs cycle and electron transport chain. |
| ‘Anaerobic respiration | Anaerobic respiration takes place in the absence of free oxygen. This process is called fermentation. |
| Krebs cycle | Krebs cycle is a series of reactions in which the pyruvate from glycolysis is oxidized to CO,. |
| Electron
transport chain |
The collection of electron carrier molecules embedded in the inner membrane of the mitochondrion is called electron transport chain. |
| oxidative
phosphorylation |
the synthesis of ATP molecule in the presence of oxygen is called oxidative phosphorylation. |
| Chemiosmosis | The coupling reaction in which synthesis of ATP molecule takes during movement of H ‘ across an 11. gradient is called Chemiosmosis. |
| Respiratory substrate | The organic substances of the cells used up in the respiratory process arc called respiratory substrate. |
| Respiratory quotient
‘ |
The ratio of the volume of carbon dioxide give out to the volume of oxygen absorbed (C0702) is called the respiratory quotient. |
