1

Step one

-After the enzyme removes a proton from the CH3 group on acetyle CoA, the negatively charged CH2- forms a bond to a carbonyl carbon of oxaloacetate. -The subsequent loss by hydrolysis of the coenzyme A drive the reaction strongly forward.

2

Step two

An isomerization reaction, in which water is first removed and then added back, moves the hydroxyl group from one carbon atom to its neighbor

3

Step three

In the first of four oxidation steps in the cycle, the carbon carrying the hydroxyl group is converted to a carbonyl group. The immediate product is unstable, losing CO2 while still bound to the enzyme.

4

Step four

-The a-ketoglutarate dehydrogenase complex closely resembles the large enzyme complex that converts pyruvate to acetyl CoA. - It likewise catalyzes an oxidation that produces NADH, CO2, and a high-energy thioeter bond to coenzyme A(CoA)

5

Step five

-A phosphate molecule from solution displaces the CoA, forming a high-energy phosphate linkage to succinate. - This phosphate is then passed to GDP to form GTP in bacteria and ATP in plants and animals.

6

Step six

In the third oxidation step in the cycle, FAD accepts two hydrogen atoms from succinate.

7

Step seven

The addition of water to fumarate places a hydroxyl group next to a carbonyl carbon.

8

Step eight

In the last of four oxidation steps in the cycle, the carbon carrying the hydroxyl group is converted to a carbonyl group, regenerating the oxaloacetate needed for step one.
