active transport
Primary Active Transport Secondary Active Transport Exocytosis/Endocytosis
The contractile vacuole collects water, then pumps it out of the cell. It requires energy to be expended, so it is a type of active transport.
Active transport is the term used to define the means of particle transport that requires input of energy from the cell. The opposite of this would be passive transport.
Facilitated diffusion = down concentration gradient, it just uses a carrier protein (doesn't need energy)Active transport =goes UP concentration gradient with the help of a carrier protein and ENERGY
active transport is different from diffusion. active transport has to do with the movement of chemical substance through a gradient of concentration. diffusion has to do with requiring the expenditure of energy
No, it is an example of active transport. Ion pumps, such as a sodium or potassium pump, use ATP for energy and pump ions across a membrane. The pumps are necessary because the ions are going against the concentration gradient (Low concentration to high concentration. Therefore, ion pumps are an example of active transport
Hydrogen (H+) pumps.
Na+-K+ ATPase pumps
selective transport is the transport of specific substances by means of protein channels and pumps.
ATPase pumps got that......
Muscle contraction , transport , nerve impulse conduction .
yes they can
Primary Active Transport Secondary Active Transport Exocytosis/Endocytosis
Active transport requires energy; passive transport does not.
n
Endocytosis is an example of active transport.
No it's active transport.
