How would you design a cell membrane that would allow you to move more material

Question

How would you design a cell membrane that would allow you to move more material through the membrane faster without taking more space? Desmosomes, gap junctions, and tight junctions connect cells to one another. What examples can you find in your external environment of analogous structures that fit each cell connection type? Would an intravenous injection of a 0.85% NaCl solution give the same osmotic pressure to the cells of the bloodstream as a 0.85% dextrose (glucose) solution? Is the osmotic pressure of 0.85% NaCl and 5% dextrose the same?

Explanation / Answer

Answer:

1. The design of a cell membrane that would allow to move more material through the membrane faster without taking more space have been discussed below:

i. To allow for a larger membrane surface area without taking up more space, you add more folds to the membrane, similar to the stucture of a microvilli.

ii. Since cell memberanes are semipermeable, having more transmembrane proteins embedded into the membrane would facilitate faster movement without taking up more space.
