Explain why, when a concentration gradient exists on two sides of membrane, that the spontaneous movement of solute molecules is from areas of high concentration towards low concentration. (hint: think of thermodynamics)
Cells transporting substances across their membranes is essential. Choose TWO of the following types of cellular transport. ๏osmosis ๏active transport ๏facilitated diffusion ๏endocytosis / exocytosis (a)For each type of transport you choose, describe the transport process. Explain how the organization of cell membrane plays a role the movement of specific molecules across membrane. (b)Using the same transport types, identify a specific cell that utilizes that type of transit (i.e. one cell for each transport type, or two different cell examples), and detail a substance that is transferred. (c)A typical human lymphocyte has a radius of about 10 μm, while a typical bacterium (e.g., S. pneumoniae) has a radius of about 1 μm. Assuming that both cell types are perfectly spherical, compare and contrastthe transport mechanisms for each of these cells.
A red blood cell with an intracellular fluid (ICF) concentration of 280 mmol/L, is placed into an environment were the concentration of the extracellular fluid (ECF) is 305 mmol/L. As a result, water will move across the cell/plasma membrane. a) Name the process by which water moves b) Describe the overall direction of movement of the water. Answer choices: (i) From outside the cell to inside the cell (ii) From inside the cell to outside the cell, or (iii) Equally, into and out of the cell iii Explain your reasoning for your answer to part (c). 1In your answer you must describe the environment on both sides of the membrane, and use 3 of the following 4 terms correctly; hypertonic, hypotonic, lower solute concentration, higher solute concentrationn (2pts -Correct use of biological terminology, and correct spelling is essential.

For the following modes of transport for membranes, tell whether the flow is with or against chemical potenial. Meaning +deltaG or -deltag A. Passive Diffusion B.Faciliated Diffusion C.Active Transport
In which direction will WATER molecules (the small blue spheres) move across the membrane in the illustration shown here? A *B: Water will move from A to B Water will move from B to A
Glucose is a large molecule that cannot penetrate the phospholipid bilayer of cells. 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? O Facilitated diffusion O Simple diffusion O Active transport O Osmosis
Which of the following is inversely related to the rate of diffusion for certain substance: a- Diffusion coefficient b- Area available for diffusion C- Width of cell membrane d- Different in concentration for the substance
For the following scenarios, determine whether the molecules in the scenario are moving by simple diffusion (S), osmosis (0), facilitated diffusion (F), or active transport (A). a)For water to travel across the cell membrane at a substantial rate, the water molecules travel through protein channels known as aquaporins b)While water molecules are polar, they are also very small. Some water molecules are able to squeeze directly through the phospholipid bilayer due to their small size. C)Charged ions such as Na* travel through a cell membrane against their concentration gradient d)Cells lining the gut need to take in glucose, but at certain times, the concentration of extraceliular glucose is lower than the concentration already stored in the cells. e)At a certain time, glucose is in a high concentration outside of a cell and needs to travel through the membrane into the cell but does so using a glucose transporter protein.
Ms. Sassa, a biology professor, wanted to demonstrate to her students the applicability of a dialyzing membrane (DM) as a model for the cell membrane by enclosing an aqueous solution in a DM bag and immersing in a beaker containing a different solution. Substances available which are permeable to the DM include 0.02 M NaCl, 0.03 M glucose, and 0.01 M glucose. The only substance available which is completely impermeable to the DM is the 0.01 M lactose. Using the substances given and materials such as a beaker, stirring rod, and string, draw ONLY ONE set-up that can be demonstrated by Ms. Sassa that will satisfy ALL of the following conditions: a. No solute will exhibit a net diffusion out of the cell. b. Glucose will exhibit a net diffusion into the cell. c. NaCl will exhibit a zero net movement. d. No net movement of lactose from the inside to outside of the cell. Make sure to label properly the substance inside the beaker and inside the DM bag.
The transport of a molecule is investigated using two chambers (left and right) separated by a synthetic membrane containing transport proteins. A solution containing varying concentrations of the molecule is added to the left side while pure water is added to the right. The transport rate of the molecule is determined by measuring the concentration of molecule that accumulates on the right side. The following table summarizes the transport rate of the molecule at various concentrations. Based on this you can conclude: a) the molecule is most likely transported by facilitated diffusion b) the molecule is moving across the membrane by passive transport c) the membrane is freely permeable to the molecule d) the molecule is most likely transported by active transport
Piston C Piston D Solution A Solution B Semipermeable membrane Above is a crude cartoon of a diffusion system. Two containers with solutions of sucrose in water are connected by a semipermeable membrane that is only permeable to water. Each container has a piston above it. Using this information answer the following. If the concentration of sucrose in solution A is 150mM and in solution B it's 2mM, which of the following would occur? al Piston D will feel an upward pressure. No diffusion will occur. Sucrose will diffuse from solution A to soluion B. Piston C will feel an upward pressure.
Distinguish 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?
