Problem : What two types of reactions does glyceraldehyde-3-phosphate dehydrogenase catalyze in the fifth step of glycolysis?

Glyceraldehyde-3-phosphate dehydrogenase first oxidizes and then phosphorylates glyceraldehyde-3-phosphate.

Problem : What is the name of the enzyme that catalyzes the reaction that converts 1,3 bisphoglycerate to 3-phosphoglycerate?

Phosphoglycerate kinase.

Problem : How many molecules of ATP are produced during the second stage of glycolysis?

There are four ATP molecules are produced during the second stage of glycolysis. They are produced in steps six and nine.

Problem : What role does atomic magnesium play in step 6 of glycolysis involving the conversion of 1,3 bisphoglycerate to 3-phosphoglycerate?

Magnesium functions to shield the negative charges that are abundant on the ATP molecule as a result of its phosphate groups.

Problem : What general name is given to an enzyme that catalyzes the transfer of a functional group from one position on a molecule to another?

A mutase.
