Membrane Transport (1 of 4): Diffusion and Passive Transport (BioFlix tutorial) Cells require a constant exchange of solutes (ions and small molecules) with the outside of the cell. Denaturation changed the three-dimensional shape of the active site of the enzyme, preventing it from binding to the substrate. nucleic acid Diagram showing how a carrier protein can bind a target molecule on one side of the membrane, undergo a shape change, and release the target molecule on the other side of the membrane. The carrier protein then changes shape and releases the target molecule into the cell. B hypertonic gained water Activation energy can be described as __________. 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). Hint 2. a) Side with a lower concentration of square molecules Membrane transport is dependent upon the permeability of the membrane, transmembrane solute concentration, and the size and charge of the solute. pinocytosis Cells use all these processes to get what we need. Pic 1 Part A. Fecilitated Diffusion. Which two of the following statements correctly describe the movement of dye molecules at equilibrium?
