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.

Visit this link (http://openstaxcollege.org/l/diffusion) to see diffusion and how it is propelled by the kinetic energy of molecules in solution. How does temperature affect diffusion rate, and why?
The difference between simple diffusion and facilitated diffusion is that facilitated diffusion O requires ATP. requires transporter proteins. does not require ATP. moves materials from a higher to a lower concentration. moves materials from a lower to a higher concentration.
Which of the following statements is correct about passive facilitated diffusion? (select all that apply) V It is a process in which molecules move from a region of lower concentration to one of higher concentration (or up a concentration gradient). O It requires a transport protein. O It requires an expenditure of energy by the cell. O It is a process in which molecules move from a region of higher concentration to a region of lower concentration (or down a concentration gradient). O It involves movement of molecules up a concentration gradient and requires a transport protein.
Which of the following are features of facilitated diffusion? There may be more than one correct answer, select all that apply. Requires energy Movement assisted by proteins Can include passive diffusion Depends on ATP hydrolysis Can include ion transport down its concentration gradient in a cell (high to low concentration)
Which of the following statements about diffusion is correct? It is an active process in which molecules move from a region of lower concentration to one of higher concentration. It is very rapid over long distances. It requires an expenditure of energy by the cell. It is a passive process in which molecules move from a region of lower concentration to a region of higher concentration. It is a passive process in which molecules move from a region of higher concentration to a region of lower concentration.
Facilitated diffusion differs from active transport in that facilitated diffusion transports against a concentration gradient while active transport does not facilitated diffusion requires expenditure of energy while active transport does not active transport requires expenditure of energy while facilitated diffusion does not facilitated diffusion involves carrier proteins while active transport does not facilitated diffusion works against a concentration gradient while active transport works only with the concentration gradient
Crossing a cell membrane by simple diffusion can be distinguished from facilitated diffusion by which of the following: Select all that apply. Simple diffusion moves molecules down a concentration gradient while facilitated diffusion moves molecules up a concentration gradient Simple diffusion does not require membrane proteins; facilitated diffusion requires specific membrane proteins Simple diffusion does not require energy; facilitated diffusion requires energy Simple diffusion is not saturable; facilitated diffusion rates are limited by the number of functional membrane proteins and can be saturated
Which of the following statements is TRUE of diffusion? Diffusion of particles along the concentration gradient will occur until particles are equally distributed in all areas of the solution. Diffusion of particles along the concentration gradient will occur until the particles move fully from one side of the solution to the other. Diffusion of particles against the concentration gradient will occur until random motion occurs. Diffusion of particles against the concentration gradient will occur until all the particles have dissolved. Carl is examining an onion root tip cell under a microscope. Based on his observations, Carl proposes that the onion root tip cell has completed interphase and is now in the first phase of mitosis.

O I and II only I and III only O Il and III only O I, Il and III
Passive transport across the membrane mediated by a carrier— would not be saturated by increasing amount of substance to be transported. does not require energy (ATP). can be driven in reverse. moves the solute through the membrane in the “uphill” direction of their concentration gradient. is faster than transport mediated by channel proteins.
