Question

Which process connects glycolysis and the citric acid cycle?What role does cellular respiration play in the carbon cycle?

Answer 1

Glycolysis and the TCA cycle are linked by the linking reaction catalysed by pyruvate dehydrogenase complex. Pyruvic acid produced at the end of glycolysis is transported to the matrix of mitochondria, where it undergoes oxidative decarboxylation to produce acetyl CoA. Acetyl CoA enters the TCA cycle.
