One form of active transport is the sodium-potassium pump, which actively transports sodium ions out of the cell and potassium ions into the cell against their concentration gradients, using ATP as energy.

Does active transport require a transport protein?
Yes, active transport requires transport proteins to move molecules against their concentration gradient, requiring energy in the form of ATP. These transport proteins facilitate the movement of specific molecules across the cell membrane.
Does active transport require water?
Yes, active transport requires energy in the form of ATP but does not specifically require water as a component for the process to occur. Water molecules may be present in the environment where active transport occurs, but water itself is not a requirement for active transport to take place.
Identify 2 methods of Active transport?
Two methods of active transport are primary active transport, which uses energy in the form of ATP to move molecules against their concentration gradient, and secondary active transport, which uses the energy stored in an ion gradient to drive the movement of other molecules.
What form of transport is not a form of passive transport?
Active transport requires energy to move substances across a cell membrane against their concentration gradient, whereas passive transport does not require energy and relies on the concentration gradient. Examples of active transport include the sodium-potassium pump and endocytosis.
What is the movement of molecules across a membrane against their concentration at the expense of ATP energy called?
Active transport. It requires energy in the form of ATP to move molecules against their concentration gradient.
Is pinocytosis acitve or passive transport?
It is the active transport of liquids in vesicles into and out of a cell so it uses metabolic energy, thus active
Is diffusion through ion channels a form of active transport?
Facilitated diffusion, or diffusion through ion channels, is not a form of active transport. It is a spontaneous passive transport.
active transport reguires?
Active transport requires some form of energy input, usually ATP
Is energy used in secondary active transport?
Yes, any form of active transport uses energy.
Is diffusion a form active transport?
False!
In cells a form of active transport is what?
One form of active transport is the vacuoles that hold the water and energy to transport to the nucleus which controls all the cell's activities!!
Exocytosis active or passive?
active
Is endocytocsis a form of passive transport?
No. Endocytosis requires the cell to expend energy, therefore it is a form of active transport.
Does active transport require a transport protein?
Yes, active transport requires transport proteins to move molecules against their concentration gradient, requiring energy in the form of ATP. These transport proteins facilitate the movement of specific molecules across the cell membrane.
What process requires cells to expend energy in the form of ATP?
Active transport processes, such as the sodium-potassium pump, require cells to expend energy in the form of ATP. The energy from ATP is needed to move molecules or ions against their concentration gradient, from an area of lower concentration to an area of higher concentration.
What types of cell transport do expend energy?
Active transport processes, such as primary active transport, secondary active transport, and vesicular transport, require the cell to expend energy in the form of ATP. These processes enable the movement of molecules or ions against their concentration gradients or across membranes.
What is an aquaglyceroporin?
An aquaglyceroporin is a form of aquaporin which is active in the transport of glycerol.
