Considering that active transport is the movement of a solute across a biological membrane such that the movement is directed upward in a concentration gradient (i.e., against the gradient) and requires the expenditure of energy. Acrtive transport is an endergonic process that is often coupled to the hydrolisis of ATP. Three types of ATP hydrolizing, transmembrane proteins or "pumps" are known that actively transport cations: a) P-type ATPases, located mostly in plasma membranes; b) F-type ATPases (F1F0), located in mitochondria; and c) V-type ATPases, located in plant vacuolar membranes and acidic vesicle, such as animal lysosomes.
The most known active transport pumps are: (Na+-K+)-ATPase of plasma membrane, Ca2+-ATPase , and (H+-K+)-ATPase of gastric mucosa.
Finally, the most known ions that use active transport are Na+, K+, and Ca2+.

What is a good sentence for Active Transport?
Active Transport is carried out in our body cells. Active Transport uses energy to transport materials.
Is testosterone a passive transport or an active transport?
it is an ACTIVE transport.
Is an active transport active or passive?
It has is in the name. Active Transport
What is it called when molecules uses energy to move across a semipermeable membrane?
Active transport
Is active transport an active or passive process?
It has is in the name. Active Transport
Describe the two methods of active transport?
Active transport involves the movement of molecules against their concentration gradient, requiring energy input. Two methods of active transport include primary active transport, where energy from ATP is directly used to move molecules, and secondary active transport, where the movement of one molecule down its gradient provides energy to transport another molecule against its gradient.
What prevents active transport taking place?
Believe it or not, cyanide kills us by inhibiting active transport, to such an extent that substances can no longer be transferred across cell membranes. This is one example of a substance that stops the process of active transport dead in its tracks.
Is coupled transport an example of active or passive transport?
Coupled transport is an example of active transport.
Differences between primary and secondary active transport?
In primary active transport, the transport protein gets phosphorylated; in secondary active transport, the transport protein is not phosphorylated
How is facilitated transport different from active transport?
Facilated transport does not need to use energy but active transport does.
How does active transport differ from passive transport-?
Active transport requires energy while passive transport does not.
What is differs between active transport and passive transport?
Active transport requires energy; passive transport does not.
