Drag the correct while Show transcribed image text Expert Answer 96% (224 ratings) Transcribed image text: Consider the movement of water when the solute concentration inside the cell is different from that of the surrounding environment. In cells, it is common for solutes to be maintained at different concentrations on opposite sides of a membrane, including the plasma membrane or an the hydrophobic interior of the membrane. a)Side with higher concentration of molecules This is because lipids are soluble in In active transport a molecule moves down its concentration gradient. Explore the interactive figure to compare different foods and different activities to see how many calories each contains or burns. Sodium ions move down the concentration gradient created by the sodium-potassium pump, and glucose moves against its concentration gradient. Other factors being equal, a stronger concentration gradient (larger concentration difference between regions) results in faster diffusion. Your email address will not be published. Save my name, email, and website in this browser for the next time I comment. The lipid bilayer is essentially impermeable to solutes that are charged. What molecule movements occur at equilibrium? The specific location within an enzyme molecule where the substrate binds is called the _____________. water This cell is in a(n) _____ solution. If a molecule wanted to diffuse across the plasma membrane, but wasn't able to make it all the way through, what would happen to it? Molecules move from a region of higher concentration to a region of lower concentration. The diffusion of water across a membrane is called osmosis. The sodium-potassium pump moves ions against their concentration gradient, from where they are less concentrated to where they are more concentrated. Certain molecules use facilitated diffusion to cross the plasma membrane. Complete the diagram below using the following steps. a receptor protein is involved The Kb of pyridine, C5H5N, is 1.5 x 10-9. b) Transport protein Thus, over time, the net movement of molecules will be out of the more concentrated area and into the less concentrated one, until the concentrations become equal (at which point, its equally likely for a molecule to move in either direction). pinocytosis It is strange, I had some troubles in the quiz because of it. detection of environmental change.
