Question

How is glycolysis related to the citric acid cycle?

Answer 1

Glycolysis produces the starting material for the Tricarboxylic Acid Cycle.

Explanation:

Each step in glycolysis converts one glucose molecule into two pyruvates.

A huge enzyme complex called pyruvate dehydrogenase links glycolysis to the Tricarboxylic Acid Cycle.

It converts pyruvate into acetyl-Coenzyme A (acetyl-CoA).

`underbrace("CH"_3"COCOO"^(-))_color(red)("pyruvate") + "HSCoA" + "NAD"^+ stackrel("pyruvate dehydrogenase")(→) underbrace("CH"_3"CO-SCoA")_color(red)("acetyl-CoA") + "CO"_2 + "NADH"`

Acetyl-Coenzyme A is the starting material for the Tricarboxylic Acid Cycle.
