Exocytosis requires the release of a neurotransmitter (a molecule or a small peptide) for the transfer of nerve impulses between adjacent nerve cells. Which of the following mechanisms would most likely follow a neurotransmitter release to return the cell to its original state? Select one or more: a. Endocytosis b. Active transport of the neurotransmitter back into the cell c Passive transport (by facilitated diffusion) of the neurotransmitter back into the cell d. Pinocytosis e. Receptor-mediated endocytosis

A) This cell would not be able to move around B) This cell would not be able to glycosylate proteins C) This cell would not be able to release proteins into the extracellur space D) This cell would not be able to synthesize proteins ..
The process of endocytosis involves the formation of vesicles called endosomes. Which of the following best describes the pH of the endosomal interior? a.) The interior of an endosome generally has a higher pH than cytoplasm. b.) The interior of an endosome generally had a lower pH than cytoplasm. c.) The interior of an endosome generally had a pH similar to cytoplasm.
Which of the following processes results in the formation of food vesicle within the cell whose contents will subsequently be digested by enzymes in the lysosome a) receptor mediated endocytosis b) phagocytosis c) pinocytosis d) exocytosis
Among the statements a, b and c, which is/are false? a) Endocytosis is the formation of vacuoles by the plasma membrane for the purpose oftransport inside the cell a small content of extracellular fluid. b) Exocytosis is the formation of vacuoles by the plasma membrane for the purpose oftransport a small amount of intracellular fluid out of the cell. c) Pinocytosis is a form of endocytosis. d) All of these statements are false. e) None of these statements is false.

When cellular transport through the plasma membrane must be provided with energy in form of ATP to power the transport process, what is this called? A. Selective permeability B. Passive transport C. Active transport D. Diffusion
Which of the following can most easily pass through the phospholipid bilayer of the cell plasma membrane without the involvement of proteins? A. small non-polar molecules B. small polar molecules C. large non-polar molecules D. large polar molecules
Which type(s) of vesicular transport is for nonspecific engulfment of fluid and materials from outside of the cell? a receptor-mediated endocytosis b exocytosis c pinocytosis d phagocytosis and pinocytosis
As a cell grows its plasma membrane expands. Does this involve endocytosis or exocytosis? ATP is not directly involved in the functioning of a co-transporter. Why, then, is co-transport considered active transport?
