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 are two major means of active membrane transport?
Two major means of active membrane transport are primary active transport, which directly uses energy in the form of ATP to transport molecules against their concentration gradient, and secondary active transport, which uses the energy stored in the electrochemical gradient of one molecule to drive the transport of another molecule against its gradient.

What type of transport is used to move a molecule from a region of low concentration to a region to a high concentration?
active transport
Which type of transport is used to move a molecule from a region of low concentration to a region of high concentrationing?
The process is called active transport, and unlike diffusion it uses energy.
What type of transport requires energy to move molecule?
Active transport requires energy to move a molecule.
What is a good sentence for Active Transport?
Active Transport is carried out in our body cells. Active Transport uses energy to transport materials.

Active transport
Is glucose molecule passive or active transport?
Secondary active transport aka facilitated diffusion [depending on your teacher].
