Cellular Respiration: CITRIC ACIT (KREBS) |
|
Definition
- Acetyl Co-A is the substrate of Citric acid cycle. Two molecules of Acetyl Co-A are produced in first stage of cellular respiration by breakdown of one molecule of glucose. In second stage, these two molecules of Acetyl Co-A are oxidized to carbon dioxide with release of two molecules of ATP, six molecules of NADH and two molecules of FADH2. One NADH provides three ATP and one FADH2 provides two ATP via the electron transport chain. Therefore, in second stage of cellular respiration, two molecules of Acetyl Co-A provide total 24 molecules of ATP. |

Term
1. ELECTRON TRANSPORT CHAIN
cellular respiration |
|
Definition
In this stage, NADH and FADH2 donate electrons. These electrons are passed along the electron transport chain from one carrier to another. Eventually the electrons combine with oxygen and hydrogen ions to form water. Free energy is released in this stage as electrons are passed along the electron transport chain from one carrier to another. One molecule of NADH releases three ATP and one molecule of FADH2 releases two ATP via the electron transport chain. |
