- Due: March 4th PROBLEM SET #3: CARBOHYDRATE METABOLISM 1. In cells, glycerol can be oxidized to glyceraldehyde-3-phosphate. Propose a theoretical two- step reaction scheme for how this might occur in cells. Be sure to draw the metabolite intermediate and list any cofactors or other substrates that would be used. Predict the class of each enzyme used to catalyze your proposed reactions. (CH₂o- ongo OH H₂C-OH H2C-OH HC-OH H2COH transferase (Kinase) I aldolase. • H-OH 0 HAC-o-P.

Answer 1

directly glyceraldehyde 3 phosphate is not produced instead DIhydroxyacetone phosphate is originated form the. Glyceraldehyde 3 phosphate is produced.
