Detailed explanation-1: -What is glycolysis? Glycolysis is a series of reactions that extract energy from glucose by splitting it into two three-carbon molecules called pyruvates.
Detailed explanation-2: -ATP and NADPH react with PGA to form PGAL. PGAL is a 3 carbon compound. Two PGAL combine to form a glucose. The remaining PGAL are turned into RuBP.
Detailed explanation-3: -Respiration of 1 molecule of glucose or 2 PGAL produces 38 ATP molecules, therefore 3 molecule of glucose, will produce 6 PGAL and 38×3=114 ATP molecules. So, the correct answer is “option b".
Detailed explanation-4: -PGAL is an intermediate metabolite produced during glycolysis. PGAL (or 3-phosphoglyceraldehyde) is chemical compound also known as glyceraldehyde 3-phosphate. Its name can be abbreviated in several ways, such as G3P, GADP, or PGAL.
