WebDec 19, 2015 · Proton pumps are a special kind of transporter that push hydrogen ions from areas of low concentration to areas with high concentration. Ions moving down a gradient release energy, but when they move up a gradient, it takes energy. Diffusion can then use this gradient to capture energy again, as the ions move downhill. WebSubstances are transported passively down concentration gradients. Often, substances have to be moved from a low to a high concentration - against a concentration gradient. Active transport... blue backsplash ideas https://craftach.com

WebDiffusion can be defined as A. the movement of water across a membrane that permits free movement of water but not solutes. B. the net movement of molecules from a region of higher concentration to a region of lower concentration. C. a process in which cells engulf particles. D. an excretory process. WebExamples of passive transport include simple diffusion, facilitated diffusion, and channel-mediated transporters. Active transport, on the other hand, requires the input of energy to move particles across a cell membrane, often against their concentration gradient. Active transport can occur through carrier-mediated transporters and pumps.
