The Na+/K+ pump is an active transport mechanism because it uses energy in the form of ATP to pump sodium ions out of the cell and potassium ions into the cell against their concentration gradients.
Ion channels let ions flow according to their own electrochemical gradient, without energy consumption. That means they are a form of passive transport.
A proton pump is passive because it is "pumping" protons throughout organisms.

Is potassium an active or passive transport?
It depends. Are you talking about Na/K pumps or Na/K co transporters? Pumps are active.
Through what type of proteins does active transport occur?
Active transport occurs through carrier proteins that pump molecules against their concentration gradient using energy from ATP. These carrier proteins undergo conformational changes to transport molecules across the cell membrane.
What is an example of primary active transport?
Sodium-potassium pump is an example of primary active transport. This pump helps maintain the electrochemical gradient across the cell membrane by actively transporting sodium ions out of the cell and potassium ions into the cell.
Which proteins are used in active and passive transport?
In active transport, proteins like pumps (such as Na+/K+ ATPase) are commonly used to move molecules against their concentration gradient, requiring energy in the form of ATP. Passive transport commonly involves proteins like ion channels and carrier proteins that facilitate the movement of molecules down their concentration gradient without requiring energy input.
What best describes the Na plus and K plus concentrations across a neuron's plasma membrane?
Na+ concentration is higher outside the neuron than inside, while K+ concentration is higher inside the neuron than outside. This concentration gradient is maintained by the Na+/K+ pump, which actively transports Na+ out of the cell and K+ into the cell, contributing to the resting membrane potential of the neuron.
Is potassium an active or passive transport?
It depends. Are you talking about Na/K pumps or Na/K co transporters? Pumps are active.
The Na-K pump is an example of active transport?
Yes, that's correct. The sodium-potassium pump actively transports sodium ions out of the cell and potassium ions into the cell against their concentration gradients using energy from ATP. This process helps to maintain the cell's resting membrane potential and is essential for cellular function.
What event initiates ATP attachment to the Na plus -K plus pump leading to the pump's phosphorylation?
The binding of Na+ ions to the pump
Through what type of proteins does active transport occur?
Active transport occurs through carrier proteins that pump molecules against their concentration gradient using energy from ATP. These carrier proteins undergo conformational changes to transport molecules across the cell membrane.
What is an example of primary active transport?
Sodium-potassium pump is an example of primary active transport. This pump helps maintain the electrochemical gradient across the cell membrane by actively transporting sodium ions out of the cell and potassium ions into the cell.
Contrast active and passive transpot.?
Active transport requires energy to move molecules against their concentration gradient, while passive transport does not require energy and moves molecules along their concentration gradient. Active transport involves protein pumps or channels that actively move molecules across the cell membrane, while passive transport relies on the natural movement of molecules without the need for additional energy input.
Are metals Na and K inactive or active?
K is potassium. Na is sodium. They are both akali metals which react violently with water. I actually did a project on potassium. I sadly actually don't know what inactive and active means.
What sort of ion distributions are established and maintained by Na -K pump activity?
high Na+ concentration in the extracellular fluid; high K+ concentration in the cytoplasm
Is the sodium potassium pump the main driving force of Na movement into a renal cell?
Yes, the sodium-potassium pump is a primary mechanism for maintaining the concentration gradient of sodium and potassium across the cell membrane in renal cells. This pump helps in the active transport of sodium out of the cell and potassium into the cell, which plays a crucial role in various renal processes like reabsorption and secretion.
Which proteins are used in active and passive transport?
In active transport, proteins like pumps (such as Na+/K+ ATPase) are commonly used to move molecules against their concentration gradient, requiring energy in the form of ATP. Passive transport commonly involves proteins like ion channels and carrier proteins that facilitate the movement of molecules down their concentration gradient without requiring energy input.
What group of metals are extremely active?
Group 1 Li, Na, K, Rb, Cs, Fr
Is the sodium potassium pump a carrier protein?
the carrier protein of Na-k pump is an ion carrier protein and the pump cannot be termed as the carrier protein its a biochemical phenomenon
