WebBecause this type of active transport is not powered directly by the energy released in cell metabolism ( see below Primary active transport ), it is called secondary. There are two kinds of secondary active transport: counter-transport, in which the two substrates cross the membrane in opposite directions, and cotransport, in which they cross ... Webexample of a primary active transport system. Sodium Potassium Pump. sodium-potassium pump. A primary active transport system that simultaneously drives Na+ out of the cell against a steep gradient and pumps K+ back in. Also called Na+-K+ ATPase. For each molecule of ATP used, ...
Give examples of primary and secondary active transport.
WebPrimary active transport moves ions across a membrane and creates a difference in charge across that membrane. The primary active transport system uses ATP to move a substance, such as an ion, into the cell, and often at the same time, a second substance is moved out of the cell. The sodium-potassium pump, an important pump in animal cells ... WebIn cellular biology, active transport is the movement of molecules or ions across a cell membrane from a region of lower concentration to a region of higher … drum tagalog
