Question

UDP-glucose pyrophosphorylase works by this mechanism:

a) It adds a phosphate group to glucose from UDP.

b) It adds a UMP molecule to glucose-1-phosphate by splitting out pyrophosphate.

c) It adds a pyrophosphate group to glucose, using UTP.

d) The phosphate group on glucose-1-phosphate becomes part of the pyrophosphate in UDP.

e) More than one of these reactions occurs.
