Which enzyme 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 conversion of galactose-1-phosphate to UDP-galactose, which is then converted to UDP-glucose by UDP-galactose 4-epimerase.
