Final answer:
In eukaryotic cellular respiration, glycolysis converts glucose to pyruvate. Pyruvate must enter the mitochondria before the citric acid cycle can begin. Acetyl CoA, derived from pyruvate, is used to deliver the acetyl group for the next stage of glucose catabolism.
Step-by-step explanation:
In eukaryotic cellular respiration, glycolysis converts glucose into pyruvate. In order for the citric acid cycle to begin, pyruvate needs to enter the mitochondria. Once inside the mitochondria, pyruvate is transformed into acetyl CoA, which is a carrier compound that delivers the acetyl group derived from pyruvate to the next stage of glucose catabolism.
