Which of the Following Enzymes Interconverts an Aldose and a Ketose

Question

Which of the following enzymes interconverts an aldose and a ketose?
A) kinase
B) isomerase
C) mutase
D) dehydrogenase
E) phosphorylase

Accepted Answer

Isomerases catalyze the interconversion of isomers, such as aldoses and ketoses, by shifting functional groups within a molecule. Kinases transfer a phosphate group from a donor molecule to a receptor molecule, mutases move functional groups within a molecule, dehydrogenases catalyze oxidation-reduction reactions involving the transfer of hydrogen ions, and phosphorylases catalyze the transfer of a phosphate group from a donor molecule to a receptor molecule.
