Homework Answers
(A) is Glucose (which is starting material for glycolysis)
(B) is Hexokinase enzyme (which convert glucose into glucose-6-phosphate)
(C) is glucose-6-phosphate (in which phosphate group is attached at 6th position)
(D) is phosphoglucose isomerase (which converts glucose-6-phosphate to fructose-6-phosphate).
(E) is fructose - 6-phosphate (having carbonyl group at 2nd carbon)
(F) is fructose-1,6biphosphate (formed by fructose-6-phosphate by the enzyme phosphofructokinase)
(G) is dihydroxy acetone phosphate (in which carbonyl group is in the middle).
(H) is glyceraldehyde-3-phosphate (having aldehyde group).

1. You have given all the enzymes and intermediates in glycolysis. Choose the right enzymes and intermediates and draw the glycolytic pathway. Decorate the diagram by adding ATP, ADP, H", NADH, NAD', P, and H20 where necessary. All the steps are reversible except 1, 3 and 10; draw appropriate arrow. First arrange the reactants in the correct order.
