10. During the Krebs Cycle, the following
steps occur:
a. The 2-carbon
Acetyl-CoA joins a 4-carbon molecule, creating a 6-carbon molecule (known as
citric acid).
b. The 6-carbon
molecule is decarboxylated a first time, losing the carbon as carbon dioxide.
The result is a 5-carbon molecule which proceeds through the cycle.
c. The 5-carbon
molecule is decarboxylated a second time, the carbon released as carbon dioxide.
d. The resulting
4-carbon molecule proceeds through the remaining steps of the Krebs Cycle where
it is reconfigured to ready it to pick up the next Acetyl-CoA.
e. During
the steps of the Krebs Cycle, 1 ATP is created via substrate level phosphorylation,
and 3 NADH + H+ and 1 FADH2 are created which then carry their load of hydrogen
ions and energized electrons to the Electron Transport Chain.
