WebThe second transport method is still active because it depends on using energy as does primary transport (Figure 5.19). Figure 5.19 The sodium-potassium pump is an example of primary active transport that moves ions, sodium and potassium ions in this instance, across a membrane against their concentration gradients. WebJan 1, 2024 · Abstract. ATP-binding cassette (ABC) proteins are mainly active primary transporters and, in plants, form a large family of more than 120 members, which are organized into eight subfamilies. In ...
WebPrimary active transport is a type of active transport that involves ATP directly. The sodium-potassium pump is one of the most famous examples of primary active transport. Active transports can be classified based on the direction molecules travel in and how many … WebDescription. Primary active transporter of a solute across a membrane, via the reaction: ATP + H2O = ADP + phosphate, to directly drive the transport of a substance across a membrane. The transport protein may be transiently phosphorylated (P-type transporters), or not (ABC-type transporters and other families of transporters).
WebTransport by pumps is called primary active because the same molecule has enzymatic activity and does the pumping unlike a secondary active transport where the roles are divided between two separate molecules; a pump that creates the gradient and symporter that moves the substance.
