Where do random motion and active transport occur in cells? How do the velocities of vesicles moving randomly and actively differ? What is the advantage cells gain in utilizing both random motion and active transport of vesicles? When is active transport advantageous, when random motion?

Q: How does the intensity of facilitated diffusion vary in relation to the concentration of the moved…

A: Facilitated diffusion is a passive movement of substances through membrane proteins. The process is…

Q: Differentiate between active transport and passive (simple) diffusion. (At least 4 differences)

A:

Osmosis

In simple words, osmosis is the slow, gradual movement of a liquid through a membrane. But there are nuances to this process. For instance, there has to be an imbalance in the distribution of solute in the liquid on either side of the membrane, which has to be semipermeable. The liquid in the region with a lower solute concentration moves to the region with a higher concentration, thereby displacing the solution in the process. The objective is to equalize the concentration of molecules on both sides of the membrane; the displacement of liquid can be viewed as a byproduct of this equalization. Since there is no energy required to carry osmosis, it is considered a passive process.
