1. What are the three key events of the Citric acid cycle?
1. Conversion of pyruvic acid(from glycolysis) into acetyl CoA. This links glycolysis to the citric acid cycle.
2. Formation of CO2 as a side product.
3. Formation of many reduced coenzymes like NADH, FADH2.
The carbon in the CO2, as mentioned in #2, can be traced back to what?
To the carbon in glucose.
What do the reduced coenzymes link?
They link the citric acid cycle to the electron transport system.
What must Pyruvic acid do before the citric acid cyle begins?
It is first converted into acetic acid and then into acetyl Coenzyme A.
How is NAD+ reduced to NADH?
By picking up electrons.
Which compound is technically the first chemical step in the CAC(citric acid cycle)?
Citric acid.
Citric acid is converted into what?
Isocitric acid.
Isocitric acid is converted into what?
Alpha-ketoglutaric acid.
In this step NAD+ is reduced to NADH, CO2 is released as well.
Alpha-ketoglutaric acid is converted to what?
To Succinyl CoA.
CoA enters here to create succinyl CoA.
NAD+ is reduced to NADH.
CO2 is released.
What is succinyl CoA converted to?
Succinic acid.
A molecule of ATP is formed, because a phosphate group is transferred the energy molecule GTP to ADP to form ATP.
CoA is released.
Succinic acid is converted into what?
Fumaric acid.
FAD is reduced to FADH2.
Fumaric acid is converted to what?
Malic acid.
Malic acid is converted to what?
Oxaloacetic acid.
NAD+ is reduced to NADH.
What does oxaloacetic acid do at this step?
It condenses with acetyl CoA(CoA) to form citric acid.
What is the net yield of energy?
2 ATP molecules.
