Bulk Transport

Concept #1: Exocytosis and Phagocytosis

Concept #2: Pinocytosis and Receptor-Mediated Endocytosis

Practice: Bulk transport requires energy.

Practice: Phagocytosis is a type of exocytosis.

Additional Problems
Phagocytosis is: a. An example of exocytosisb. An example of active transportc. An example of diffusiond. An example of endocytosise. An example of facilitated diffusion
The process often thought of as “cell eating” isa. osmosisb. pinocytosisc. phagocytosisd. diffusione. active transport
Using a series of simple drawings, sketch out exocytosis: when molecules (contained in a vesicle) move from inside the cell to out.
Phagocytosis is a process that cells only use to obtain nutrients. a. Trueb. False
An organism with a cell wall would most likely be  unable to take in materials through… a. diffusion. b. osmosis. c. active transport. d. phagocytosis. e. facilitated diffusion.  
Bulk transport by endocytosis a. removes existing portions of the plasma (cell) membrane. b. adds new portions of the plasma (cell) membrane. c. has no effect on existing plasma (cell) membrane. d. results in materials leaving the cell.
When a vesicle fuses with the plasma membrane, this is an example ofa. Endocytosisb. Exocytosisc. PhagocytosisPlease draw a cartoon of this process:
How does endocytosis occur? How does exocytosis occur?- That is, what happens to membrane lipid and what kind of protein come to help.
Explain how substances get across membranes and into the cell.
What's the difference between phagocytosis and pinocytosis?
Phagocytosis and the ultimate digestion of the material that is phagocytosed involves all of the following EXCEPT:A. lysosomesB. cytoskeletal movementC. enzyme activityD. synaptic signaling
The digestion of a foreign cell in the body is called:A. Cell lysisB. AgglutinationC. NeutralizationD. PhagocytosisE. Microphages
Once a substance is engulfed into cells, which structure determine their fate? What happens if it is a toxic or bact debris?
Compare and contrast carrier proteins and channel proteins. Include information about both structure and mechanism of transport.
