Test yourself Many cell surface trans membrane proteins, called glycoproteins, have an attached carbohydrate group, 1. ich faces the extracellular space. This carbohydrate group is attached to the protein when it is still in the rER. Is the carbohydrate attached to the side of the protein that faces the lumen of the rERo the cytosol 2.Explain why the orientation of a transmembrane protein (i.e. which side of the protein faces the inside and which side faces the outside of the...

Which of the following statements correctly matches a membrane
protein with its function.
-Structural proteins bind to molecules to facilitate entry to
or exit from the cell.
-Carrier proteins form water-filled channels that allow
molecules to pass through.
-Channel proteins are classified as uniport, symport, or
antiport carriers.
-Receptors transmit signals from the extracellular environment
to the cytoplasm of the cell.
During the cephalic phase of gastric secretion,
-there is an increased flow of action potentials along the

Which of the following statements about the role of the COPI or COPII proteins in vesicular transport is CORRECT? They pinch and fuse the membrane to allow separation of the vesicle from the rest of the membrane of the donor compartment. They increase the curvature of the membrane and form the vesicle from the donor compartment. They bind to the membrane of the target organelle/compartment to ensure delivery specificity. They regulate the fusion of the vesicle membrane with its target...
