What else can I help you with?
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.
What ions create a gradient?
Ions that create a gradient typically include sodium (Na⁺), potassium (K⁺), calcium (Ca²⁺), and chloride (Cl⁻). These ions establish electrochemical gradients across cell membranes through active transport and passive diffusion. For instance, the sodium-potassium pump actively transports Na⁺ out of the cell and K⁺ into the cell, creating a concentration gradient essential for functions like nerve impulse transmission and muscle contraction. The movement of these ions creates a difference in charge and concentration, which is crucial for cellular processes.
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.
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?
Bulk Transport is an example of active transport. The process by which amoeba engulfs its food and secretes is a type of active transport. Amoeba forms false feet like pseudopodia and engulf food.Active and Passive transport both are related with plasma membrane. Active Transport is the transport of food across plasma membrane with expenditure of energy.
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

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.?
PASSIVE TRANSPORT: when there is a transport of solutes from there higher concentration to their lower concentration across the semipermeable membrane as plasma membrane without any utilization of energy is called passive transport. ACTIVE TRANSPORT: When there is a net flow of solutes from there low concentration to their high concentrain of flow against the concentration gradiant with the utilization of energy is called active transport. e.g. Na+- K+ exchange pump.
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
