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.Which of the following describe active transport or is an example of act transport of a substance across a membrane? Choose all correct answer Glucose transport into intestinal epithelial cells Glucose transport into muscle cells Na* ion pumping out and K* ion pumping into the cell Transport requires a mediator Requires input of energy for transport Movement of ligand against the concentration gradient
- Select the correct statments regarding transport of molecules across the cell membrane. Non-mediated transport is susceptible to saturation of transporter/channel proteins. Channels and transporters need not use energy to transport solute down the concentration gradient. The Na+/K+ antiport takes advantage of electrochemical gradients to exchange Na+ and K+ ions across the cell membrane. Active transport via electrochemical gradients relies on the passive transport of one solute to transport a second solute against the concentration gradient. Describe the three main sources of membrane fluidityWhich of the following statements about active processes of membrane transport is true? cellular energy is required substances move against its concentration gradient all requires the aid of proteins during transport a and b a, b, and cIn facilitated diffusion and active transport, how do transport proteins affect the rate of movement of molecules across the phospholipid selectively permeable membrane? A Transport proteins decrease the rate of movement of molecules. B Transport proteins stop the rate of movement of molecules. © Transport proteins increase the rate of movement of molecules. Transport proteins ensures all molecules may pass the membrane simultaneously.
- Which is the complete description of active transport? The movement of molecules from an area of higher concentration to an area of lower A concentration across a selectively permeable membrane which uses metabolic energy from ATP. The movement of molecules from an area of higher concentration to an area of lower B concentration across a selectively permeable membrane which does not use metabolic energy from ATP. The movement of molecules from an area of lower concentration to an area of higher C concentration across a selectively permeable membrane which uses metabolic energy from ATP and transport proteins. The movement of molecules from an area of lower concentration to an area of higher D concentration across a selectively permeable membrane which does not use metabolic energy from ATP and transport proteins.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.Which of the following statements about passive processes of membrane transport is false? cellular energy is not required substances move along its concentration gradient all require the aid of proteins during transport a and b a and c
