Secondary active transport In secondary active transport, in contrast to primary active transport, there is no direct coupling of ATP; instead, the
In addition, primary and secondary active transport proteins can also be subcategorized by the number and direction of the molecules being transported. This creates the following three categories: UniportTransport Proteins — Only one type of molecule is moved via a transport protein. Movement can ...
Primary active transport: the energy from hydrolyzing ATP is directly coupled to the movement of sodium ions across a biological membrane Secondary active transport: where one substrate moves down its concentration gradient while the other moves against the concentration gradient. Two types of transporter...
What are the difference between primary active transport and secondary active transport? Describe how active transport works using the Sodium-Potassium pump. Explain the difference between the energy requirements of passive transport, primary active transport, and secondary active transport. ...
Active transport Primary active transport systems use the energy derived from ATP or light to pump particles across a membrane. Secondary active transport systems use the energy contained in the electrochemical gradient to transport particles across a membrane. Energy for driving Active Transport...
move the material—these proteins are analogous to pumps. Some pumps, which carry out primary active transport, couple directly with ATP to drive their action. In secondary transport, energy from primary transport can be used to move another substance into the cell and up its concentration ...
As in the case of coenzyme-linked enzyme reactions, primary and secondary translocation reactions are linked when a pair of translocators share a substrate or a cotranslocator.PETER MITCHELLComprehensive BiochemistryMitchell, P. 1967.

Mutations in regions interacting with a substrate in the transition state in carrier movement, as well as in the initial binding sites, can also be distinguished. The analysis applies to both primary and secondary active transport. 展开 关键词: UNCOUPLED TRANSPORT COTRANSPORT MUTATION LACTOSE PERMEASE...
To call this process secondary active transport is appropriate since the existence and maintenance of the concentration gradient of the driving ion is accomplished by primary active transporters (i.e., pumps). Sodium serves as the driving ion in many (but not all) secondary active transporters ...
