How many times does decarboxylation occur in the aerobic breakdown of one glucose molecule and when does it occur?
Decarboxylation occurs six times in the aerobic breakdown of one glucose molecule.
A glucose molecule contains 6 carbon atoms, and each one must be converted into
Glycolysis first converts the glucose molecule into two three-carbon fragments (pyruvate).
These fragments are then fed into the Tricarboxylic Acid Cycle in a preparatory step.
Preparatory step
The first carbon atom of pyruvate is removed as
The Tricarboxylic Acid Cycle Here's an overview of the Tricarboxylic Acid Cycle.
The remaining two carbons are lost as Step 3. Isocitrate to α-ketoglutarate The second molecule of Step 4. α-Ketoglutarate to succinyl-CoA Here's where the third molecule of

Decarboxylation occurs twice in the aerobic breakdown of one glucose molecule. It occurs during the Krebs cycle, specifically in the conversion of isocitrate to alpha-ketoglutarate, and in the conversion of alpha-ketoglutarate to succinyl-CoA.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
