Which of the following enzymes is involved in the conversion of galactose to glucose in the Leloir pathway?

A Galactose-1-phosphate uridyltransferase ✓
B UDP-galactose 4-epimerase
C Galactokinase
D Phosphoglucomutase

Explanation

Galactose-1-phosphate uridyltransferase catalyzes the transfer of a UDP group from UDP-glucose to galactose-1-phosphate, converting it to UDP-galactose, which can then be converted to UDP-glucose.
