Other names
A
Citric acid cycle
2
Q
Definition
A
Is a series of closed system of enzyme controlled pathway reaction
3
Q
Overall summary
A
oxaloacetate 4C accepts 2C acetyl from acetyl coA to from citrate 6C. The citrate is then is converted back to oxaloacetate in a series of small reaction.

Q
Stages
A
- oxaloacetate 4c accepts 2c acetyl to from citrate.
- decarboxylation of citrate; 2co2 is released as waste gas
- dehydrogenation of citrate; hydrogen is accepted by 3NAD and FAD to be reduces
- substrate linked phosphorylation; inorganic phospahte from intermediate substrate is transferred to adp to from ATP
5
Q
final product
A
- 1 FADH2
- 3 NADH
- 2CO2
- ATP
6
Q
most important use
A
the h released from citric acid cycle is used to generate ATP in oxidative phosphorylation(final stage)
