Terms in this set (19)
glycogen storage and breakdown is ___ regulated
a ___ acid is added in the breakdown of the glycosidic bond by the enzyme ___ phosphorylase to form glucose-1-phosphate and glycogen shortened by __ glucose unit.
phosphoric, glycogen, 1
phosphorolysis doesn't require atp, so for every glucose from glycogen, there is a net of __ ATP
the enzyme phosphoglucomutase catalyzes the isomerization of glucose-__-phosphate to glucose-__-phosphate
glycogen must first be __ before it can be a substrate for phosphorylase
the debranching enzyme for glycogen removes __ alpha 1-4 linked glucoses from the limit branch to the end of another branch.
the debranching enzyme catalyzes the hydrolysis of the alpha __-___ linked residue at the branch point.
glucose must be activated to ______ before it is added to the growing glycogen molecule
the reaction is driven by the hydrolysis of the inorganic ___.
the products and the reactants of the first reaction are at or __ to equilibrium ∆G⁰

glycogen synthase can only add UDP-glucose to an __ glycogen chain
the branching enzyme transfers a segment about __ glucoses in length from the end of a growing chain to a branch point where an α(__-__) linkage is made.
