Question 19

The enzyme triose phosphate isomerase catalyzes this important reaction in glycolysis (the breakdown of glucose):

Accepted Answer

Triose phosphate isomerase catalyzes the conversion of dihydroxyacetone phosphate and glyceraldehyde 3-phosphate, which are isomers of each other, to maintain equilibrium between the two compounds. This reaction does not involve the transfer of electrons or involve a change in the oxidation state of the carbon atoms in the reactants, so it is neither an oxidation nor a reduction.
