Upon digestion of starch, maltose, one of its degradation products, is further hydrolyzed into its monosaccharide components prior to intestinal absorption and entry into the glycolysis. Calculate the number of ATP molecules produced from the digestion and complete oxidation of 1 molecule of maltose considering the glycerol 3-phosphate shuttle. Answer the following items using numerical value only (e.g. 1 not "1 ATP") which will help you arrive at the final answer for this question. a. Total number of glucose molecules entering glycolysis: b. Total number of pyruvate molecules produced at the end of glycolysis: c. Total number of mitochondrial NADH produced after pyruvate is acted upon by the pyruvate dehydrogenase complex:

Upon digestion of starch, maltose, one of its degradation products, is further hydrolyzed into its
monosaccharide components prior to intestinal absorption and entry into the glycolysis. Calculate the
number of ATP molecules produced from the digestion and complete oxidation of 1 molecule of maltose
considering the glycerol 3-phosphate shuttle. Answer the following items using numerical value only (e.g. 1
not "1 ATP") which will help you arrive at the final answer for this question.

Expert Solution
Step 1

Monosaccharides are simple carbohydrates or sugars soluble in water, and insoluble in nonpolar solvents. Glucose is a monosaccharide. The maltose gets hydrolyzed to Glucose and glucose-1-phosphate. Glucose and Glucose-1-phosphate both are involved in the process of Glycolysis.
