Concept explainers
(a)
To determine: The flux of molecules when the size of molecule increases.
Introduction: Flux is defined as the rate of diffusion per unit surface area of a membrane. Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration.
(b)
To determine: The flux when there is an increase in the concentration gradient.
Introduction: Concentration gradient is described as the difference in the concentration of a molecule or ion between two regions. It is also known as chemical gradient.
(c)
To determine: The flux when there is a decrease in the surface area of a membrane.
Introduction: The flux of a molecule across the membrane is described as the rate of diffusion rate per unit surface area of membrane.

- Which of the following processes requires the cell to expend metabolic energy directly (e.g., from ATP)? (a) osmosis (b) facilitated diffusion (c) all forms of carrier-mediated transport (d) active transport (e) simple diffusionarrow_forwardThe distinctive properties of facilitated diffusion are: (a) Increase the speed of diffusion of substances (b) Transport of substances towards increasing concentration Additional energy consumption for transport (c) Transfer of substance involving carriers (d) Integration flux of substance and ion transport (e)arrow_forwardDistinguish between simple diffusion (SD), facilitated diffusion (FD), and active transport (AT) across a membrane for the following questions. (a) Which processes are energy dependent? (b) Which processes need some kind of carrier protein(s)? (c) Which processes can be saturated by substrate? (d) Which processes can establish a concentration gradient? (e) How much energy does it take to transport an uncharged substrate in, if its starting inside concentration is 10-fold greater than outside?arrow_forward
- Diffusion is important in body fluids because this process tends to:(a) increase local concentration gradients. (b) eliminate local concentration gradients. (c) move substances against their concentration gradients. (d) create concentration gradients.arrow_forwardFactors that affect the rate of diffusion through a membrane include all of the following EXCEPT: a)membrane surface area. b) molecular weight. c) availability of energy. d) steepness of concentration gradient.arrow_forwardTwo NaCl solutions, Solution A and Solution B, are separated by a selectively permeable membrane. You observe that the movement of solvent is from Solution B to Solution A. Which solution initially had the higher salt concentration? Question 2 options: a) solution A b) solution B c) Neitherarrow_forward
- Whether in a gas, a liquid, or a semisolid, diffusion always occurs a). at the same rate. b). from high to low solute concentration. c). faster at lower temperaturesd). from low to high solute concentration.arrow_forwardWhich of the following statements is correct about diffusion? a) It is an active process in which molecules move from a region of lower concentration to one of higher concentration. It is a passive process in which molecules move from a region of higher concentration to a region of lower concentration. c) it requires integral proteins d) It is a rapid processarrow_forwardWhich statements are consistent with the known facts about membrane transport? (a) Active transport moves a substance from a region in which its concentration is lower to one in which its concentration is higher. (b) Transport does not involve any pores or channels in membranes. (c) Transport proteins may be involved in bringing substances into cells.arrow_forward
- As molecular weight increases.a). the rate of diffusion remain unchanged.b). the rate of diffusion decreases.c). the rate of diffusion increases.d). the rate of diffusion stops.arrow_forwardWhich statements are consistent with the fluid-mosaic model of membranes? (a) All membrane proteins are bound to the interior of the membrane. (b) Both proteins and lipids undergo transverse (flip-flop) diffusion from the inside to the outside of the membrane. (c) Some proteins and lipids undergo lateral diffusion along the inner or outer surface of the membrane. (d) Carbohydrates are covalently bonded to the outside of the membrane. (e) The term mosaic refers to the arrangement of the lipids alone.arrow_forwardThe intracellular salt content of a red blood cell is about 150 mM. The cell is put in a 500 mM salt beaker. (a) Describe what will happen to the cell in terms of osmosis if the cell membrane is permeable to water but not to ions. (b) Which direction would solutes diff use if the membrane was permeable to ions: into or out of the cell?arrow_forward
