B) are produced only on free ribosomes in the cytoplasm
C) are identical to pectins between the primary walls of plant cells
D) digest bacteria outside hte cell, in the same way lysosomes do inside the cell.
E) provide support and anchorage as part of hte extracellular matric

Answer 1

I don't really like ANY of these answers, but if I had to pick one, I'd answer E.

I don't like E because wile some glycoproteins are part of the extracellular matrix, other secreted glycoproteins are found in the blood and don't have anything to do with the extracellular matrix.
