Glucose molecule runs Krebs cycle twice

Question

Why we can say that each glucose molecule runs Krebs cycle twice?

Answer 1

Each and every glucose molecule ‘cycles’ the Krebs cycle two times because subsequent to glycolysis each and every used glucose has produced two pyruvic acid molecules and each and every pyruvic acid is transformed into a 1:1 proportion in acetyl CoA. Each and every acetyl CoA then cycles Krebs cycle once.
