Which of the following are examples of diffusion (either passive or facilitated)? Glucose in the bloodstream moves through a GLUT channel in to a cell where its concentration is low ATP is expended by the Na/K ATPase to pump three sodium ions out of the cell and two potassium ions in SGLTS use a pre-established sodium concentration gradient to pump glucose in to the cell Small particles can move freely through the outer mitochondrial membrane down their concentration gradient Steroid hormones pass through the cell membrane and bind to receptors in the nucleus Hydrogen ions are pumped out of the mitochondrial matrix--where pH is high--in to the intermembrane space--where pH is low

1:58 l 5GE Done 11 of 23 3 of 12 During an investigation on membrane transport, a researcher exposed bacterial cells to different concentrations of two different solutes: A and B. The rate of transport of each solute into cells is represented in the graph. = Solute A = Solute B Solute Concentration Which of the following best explains the greater rate of transport for solute A than for solute B at higher solute concentrations? Solute A is being transported by simple diffusion, which does not rely on membrane proteins to control the rate of transport. A Solute A is being transported by active transport, which uses ATP and has higher rates of transport than passive transport. B Solute A is being transported by facilitated diffusion, which uses membrane proteins to increase the rate of transport. Submit !! Rate of Transport II

4 IIII I 5 IIIII 6 Which statement is accurate concerning simple diffusion and facilitated diffusion? In facilitated diffusion, molecules only move with the aid of a protein in the membrane. In simple diffusion, molecules move down the concentration gradient but in facilitated diffusion molecules move up the concentration gradient. Simple diffusion is passive but facilitated diffusion is an active process that uses energy. Simple diffusion requires molecules to move through special doorways in the cell membrane. étv A O Aa

Diffusion and osmosis classification Classify the following characteristics based on whether they are describing diffusion, osmosis, or both. Diffusion Results in an Can occur with equal distribution of solute molecules or without a membrane Always involves the movement of water Requires a semi-permeable membrane Osmosis Involves the movement of gases, ions, and small water soluble molecules Passive form of movement that requires no energy Moves from areas of high concentration to low Both Diffusion and Osmosis Responsible for gas exchange in the lungs concentration A 3 of 15 Next > Cation to open the document "Epicinstaller-13.0.0-fortnite-a8e4f12cada646caa706d8be407be69f (3).msi". tv 22
