Anaerobic glycolysis of which of these produces 3 ATPs per unit glucose consumed?
(A) Amino acid (B) Fructose (C) Galactose (D) Glycogen
(D) Answer- D. GlycogenAnaerobic glycolysis of glycogen produces 3 ATPs per unit glucose consumed.Consumption of ATP at the level of hexokinase is not required when we sta from glycogen as a substrate. As there is no glucose-6- phosphatase in muscle, glucose-6-phosphate directly enters into glycolysis. Hence, net ATPs are 4-1 = 3 ATPs.
