49+ Biology Active Transport Diagram Pictures. Electrochemical gradients and the membrane potential. The movement of substances into/out of cell through the membrane, against the concentration gradient (from low to high).
Primary active transport moves ions across a. Active transport is the movement of molecules up their concentration gradient , using energy. In these cases, active transport is required.
However, we're going to look at the light side:
How does active transport work? Active transport requires cellular energy to achieve this movement. In eukaryotic organisms, the electron transport chain is found embedded in the inner membrane of the mitochondria, in bacteria it is found in the cell membrane, and in case of. The second transport method is still active because it depends on using energy as does primary transport ((figure)).
