1. Reduces the chromosome number from diploid to haploid
2. Ensures that each of the 4 gametes has a complete set of chromosomes
<span>The correct answer is b: Coenzyme A.</span>
During the process of pyruvate oxidation, acetyl CoA molecule is produced. Pyruvate oxidation is the link between glycolysis and Krebs cycle and it converts pyruvate (three-carbon molecule) into acetyl-CoA ( two-carbon molecule attached to Coenzyme A). NADH is produced and one CO2 released. AcetylCoA is the substrate for the next stage of cellular respiration, citric acid cycle.
Enzymes split the DNA molecule into two rails and then transport corresponding nitrogen bases to each rail. I think this is the answer
