Which of the following describes a purpose of the glycosylation of proteins? A. Glycosylation tags a protein for destruction within a cell. B. Glycosylation is a process that causes cells to import new proteins from the extracellular space. C. Glycosylation indicates where a protein belongs within a cell. D. Glycosylation is the process of bonding amino acids to each other to build a protein.
