Citric Acid Cycle questions
a) Since carbons arrive from glucose via acetyl CoA, what carbons from glucose are in Acetyl CoA? Number them in Acetyl CoA using the original number from glucose.
b) Are any carbons from acetyl CoA removed as CO2 during the first "turn" of the citric acid cycle?
c) What glucose carbon(s) is (are) the first to be removed as CO2 in the citric acid cycle?

1. In untreated Type 1 diabetes, the hepatocyte's citric acid cycle becomes overwhelmed with acetyl-CoA fr Map excessive fatty acid oxidation. Although the excess acetyl-CoA is not toxic, it must be diverted into the formation of ketone bodies: acetone, acetoacetate, and D-(hydroxybutyrate.
What problem would arise if the excess acetyl-CoA were not converted to ketone bodies?
How does the diversion to ketone bodies solve the problem?
