Step by step
Solved in 3 steps with 3 images
- List the means of unassisted membrane transport.Which of the following methods of transport is being used to transfer the substance into the cell in the accompanying graph? a. diffusion down a concentration gradient b. osmosis c. facilitated diffusion d. active transport e. vesicular transport f. It is impossible to tell with the information provided.Assume that a membrane permeable to Na+ but not to Cl- separates two solutions. The concentration of sodium chloride on side 1 is higher than on side 2. Which of the following ionic movements would occur? a. Na+ would move until its concentration gradient is dissipated (until the concentration of Na+ on side 2 is the same as the concentration of Na+ on side 1). b. Cl- would move down its concentration gradient from side 1 to side 2. c. A membrane potential, negative on side 1, would develop. d. A membrane potential, positive on side 1, would develop. e. None of the preceding is correct.
- Define the difference between passive transport and active transport, and give examples of each. Each example should specify the type of cell, the name of the membrane protein(s), and the substance that is being transported.1) You are studying a transport protein. It appears to bind temporarily to the molecule to be transported. During normal transport, no energy is expended. The addition of a particular molecule that closely resembles the normally transported molecule inhibits transport. An increase in the concentration of the normally transported molecule in the presence of a constant concentration of the inhibitor increases the rate of transport. What kind of transport is described? 2) What are peripheral membrane proteins?What factors affect the degree of membrane fluidity?
- Describe the different types of membrane transport. Which require energy, and which are passive?List three types of movment displayed by molecules in the plasma membrane. Which type of molecule is capable of each movement.Describe the fluid properties of the cell membrane and explain how membrane fluidity is influenced by membrane composition.
- List the following from which is MOST permeable to LEAST permeable to an intact cell membrane water glucose RNA Na+ >Define cell membrane transport and membrane selectivity. Explain why the plasma membrane is selectively permeable. List and discuss which molecules can and cannot cross the membrane and explain why. Discuss why some molecules can cross directly while others require transport proteins.Identify how each of the following would pass through the plasma membrane: gases, large polar molecules, charged molecules (like ions), hydrophobic molecules, and small polar molecules. Be specific.
