What does the conformation-sensing enzyme GT do if it binds to a misfolded or incompletely folded glycoprotein?
A)It degrades the oligosaccharide chain.
B)It adds a single mannose back to one of the glucose residues at the exposed end of the recently trimmed oligosaccharide.
C)It adds a single glucose back to one of the mannose residues at the exposed end of the recently trimmed oligosaccharide.
D)It degrades the protein.
E)It refolds the protein on its own.

The conformation-sensing enzyme GT (glucosyltransferase) adds a single glucose back to one of the mannose residues at the exposed end of the recently trimmed oligosaccharide, allowing the glycoprotein to re-enter the folding cycle.
