The cytoplasm of a certain cell is composed of a solution that is 98% water, 2% solutes. Consider the solution shown in the beaker in this picture: FOOE OOS Foor solution. [Select] Cytoplasm is 98% water, 2% solutes. The solution in the beaker would be considered when compared to [Select] The plasma membrane is impermeable to solutes. Beaker solution is 98% water, 2% solutes the cell. We would expect that the cell would [Select] if it was placed in the would account for whatever changes might occur to the volume of the cytoplasm of the cell when it is placed in the solution.
In figure 4-7 why does facilitated diffusion have a maximum rate of diffusion?
Facilitated diffusion is a lipid-mediated process. true false
Examine the graph presented here. Using your knowledge of how the processes work, label each curve as representative of either simple diffusion or facilitated diffusion. Explain how you determined which curve was which.

Which of the following requires a specific interaction with the molecules or substance it is going to take into the cell? fluid-phase endocytosis transcytosis PRE pinocytosis phagocytosis receptor-mediated endocytosis
You were introduced to osmosis in Chapter 8 earlier in the course. This week, Chapter 15 continues this discussion by introducing the cell membrane. For additional information, review one or two of the websites listed below. Osmosis: Real-life Applications How Is Osmosis Used in Kidney Dialysis? Guide to Forward Osmosis Applications Choose one way that osmosis and membranes are used in living things, medicine or industry. Describe how osmosis and membranes are used in the real-life application you chose. What are some of the materials necessary? Is an input of energy necessary?
Statement 1: The direction of diffusion of a solute across a membrane is determined by its concentration gradient and always moves toward equilibrium. Statement 2: In passive transport, solutes move down the gradient from a region of low concentration to a region of high concentration. A Both statements are true. Both statements are false. C) Statement 1 is true. Statement 2 is false. Statement 1 is false. Statement 2 is true.
Aldosterone is a steroid hormone that freely enters the target cells to act within the cell. Epinephrine is a polar monoamine (amino acid) hormone that interacts with receptors on the cell's surface. What accounts for this difference? [Select any/all that apply.] Steroids are charged and hydrophilic, so aldosterone passed through a transport protein. Steroids are hydrophobic so aldosterone passed through the membrane by simple diffusion. Epinepherine (amino acid) hormone is hydrophilic, so it cannot diffuse through the phospholipid bilayer. Epinepherine (amino acid) hormone could diffuse through the phospholipid bilayer but it is attracted to the receptor protein.
Rate of diffusion through a membrane is: Group of answer choices Inversely proportional to the surface area of the membrane. Directly proportional to the thickness of the membrane. Directly proportional to the concentration gradient. All of the above.
Which of the following regarding the sodium potassium pump is FALSE? It tends to be found on the apical plasma membrane of polarized cells It transports three sodium ions to the outside of the cell It transports two potassium ions to the inside of the cell. It helps to maintain unequal distribution of ions across the plasma membrane
Without saturation of transport proteins and under the same concentration gradient how can the speed of simple diffusion be compared to the speed of facilitated diffusion?
