Detailed explanation-1: -So, the correct option is ‘ acetyl CoA’.

Detailed explanation-2: -The transition reaction connects glycolysis to the citric acid (Krebs) cycle. The transition reaction converts the two molecules of the 3-carbon pyruvate from glycolysis (and other pathways) into two molecules of the 2-carbon molecule acetyl Coenzyme A (acetyl-CoA) and 2 molecules of carbon dioxide.

Detailed explanation-3: -Pyruvate, the product from glycolysis, is transformed into acetyl CoA in the mitochondria for the next step. The citric acid cycle, where acetyl CoA is modified in the mitochondria to produce energy precursors in preparation for the next step.

Detailed explanation-4: -Fructose-6-phosphate is an intermediate of glycolysis. Fructose-1-phosphate is acted upon by an aldolase-like enz that gives DHAP and glyceraldehyde. DHAP is a glycolysis intermediate and glyceraldehyde can be phosphorylated to glyceraldehyde-3-P.
