Web19 dec. 2015 · 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. In a cell, using energy to move ions uphill when there are already lots of ions there seems a bit odd. WebActive transport mechanisms, collectively called pumps or carrier proteins, work against electrochemical gradients. With the exception of ions, small substances constantly pass through plasma membranes. Active transport maintains concentrations of ions and other substances needed by living cells in the face of these passive changes.

WebThese pumps are an example of active transport—transport that requires energy from some other sources in order to move the desired substrates. Typically, the ion pumps are driven by energy acquired from ATP hydrolysis. The main features of active transport are: Molecules are moved against the concentration gradient.
