Textbook Question
Chapter 3, Problem 2AWK
The sodium-potassium pump is a large protein molecule. Where do you think the sodium-potassium pumps are made in the cell, and how do you think they become inserted into the lipid bilayer of the plasma membrane?

What is Endoplasmic reticulum (ER) ?
While performing fluorescent microscopy to observe the transport of bulk molecules into a cell a researcher uses a green, fluorescent bulk protein and a red fluorescent dye to stain the cell membrane. If the cell has the ability to transport the bulk proteins into the cell, what would we expect to see in the microscope when the images are merged? What would we expect to see if the cell did not have the ability to transport the bulk protein?

Instead, glucose enters most cells, such as red blood cells, through special carrier proteins embedded in the surface of the plasma membrane. In doing so, glucose moves from an area of high concentration to an area of low concentration. Based on this information, which term best describes the uptake of glucose by red blood cells?
