Colls release proteins such as enzymes, hormones, and antibodies. Before release, the proteins are carried in transport vesicles to the
plasma membrane. Which process occurs at the plasma membrane that allows the protein to be secreted into the extracellular
environment?
A) the vesicle degrades the plasma membrane
B) the vesicle punctures the plasma membrane
C) the vesicle fuses with the plasma membrane
D) the vesicle binds to carbohydrates in the plasma membrane
