A nucleotide-sugar coenzyme involved in carbohydrate metabolism (UDP-glucose) is formed when UTP reacts with a glucose molecule. More UTP is made available for additional reactions by the transfer of a phosphate group from:.
a. ATP.
b. UDP.
c. ADP.
d. UTP.
e. Another carbohydrate.

b. UDP

Explanation:

Uridine diphosphate glucose (UDP) is a nucleotide sugar involved in galactose metabolism. In this reaction, the galactose 1-phosphate uridylyltransferase (GALT) enzyme transfers a phosphate group from UDP-glucose to galactose 1-phosphate in order to convert galactose into glucose
