31 Active Transport Drawing
Those proteins do much of the work in active transport. Small substances constantly pass through plasma membranes. Web active transport requires energy to move substances against a concentration or electrical gradient, like a canoeist paddling upstream. Web active transport usually happens across the cell membrane. A detailed edit history is available upon request.
Small substances constantly pass through plasma membranes. Web active transport is the process of transferring substances into, out of, and between cells, using energy. This exports three sodium ions in return for two potassium ions. The passage of some substances through membranes against a concentration gradient is unidirectional but not coupled to ionic movement even though atp is consumed in the process. Passive transport, on the other hand, does not require energy as substances move along their gradient, similar to a.
Those proteins do much of the work in active transport. In some cases, the movement of substances can be accomplished by passive transport, which uses no energy. Web primary active transport moves ions across a membrane and creates a difference in charge across that membrane, which is directly dependent on atp. Web active transport requires energy to move substances against a concentration or electrical gradient, like a canoeist paddling upstream. Active transport maintains concentrations of ions and other substances needed by living cells in the face of these passive movements.
