How can the cell move sodium out of the cell?
Cells can move sodium out of the cell using a protein called the sodium-potassium pump. This pump actively transports sodium ions out of the cell while bringing potassium ions into the cell, maintaining the proper balance of ions inside and outside the cell. This process requires energy in the form of ATP.
What is the process of the plasma membrane pumping excess sodium out of a cell into an environment where there is lower concentration of sodium called?
The process of the plasma membrane pumping excess sodium out of a cell into an environment with lower sodium concentration is called active transport. Specifically, this is often facilitated by the sodium-potassium pump (Na+/K+ ATPase), which uses ATP to move sodium ions out of the cell while bringing potassium ions in. This mechanism helps maintain the cell's electrochemical gradient, crucial for various cellular functions.
How does lactose enter the cell using the sodium gradient?
Lactose enters the cell through a process called secondary active transport, which utilizes the sodium gradient established by the Na+/K+ ATPase pump. This pump expels sodium ions (Na+) from the cell, creating a lower concentration of sodium inside compared to the outside. As sodium ions flow back into the cell down their concentration gradient, they couple with lactose via the sodium-glucose co-transporter (SGLT) or similar transporters, allowing lactose to enter the cell against its concentration gradient. This process effectively leverages the energy stored in the sodium gradient to facilitate lactose uptake.
Passages that permit a cell membrane to be permeable as needed are called?
Passages that permit a cell membrane to be permeable as needed are called ion channels. These channels allow ions such as sodium, potassium, and calcium to flow in and out of the cell, regulating the cell's electrical and chemical properties.
What pumps in the cell membrane?
The sodium potassium pump is a form of active transport in which sodium and potassium end up switching places (one into the cell and one leaves the cell). The pump is located in the cell membrane.

The mechanism that prevents sodium ions from building up inside the cell is called what?
the sodium-potassium purmp
The outer covering of a cell that controls what enters and leaves is called the?
The outer covering of a cell that controls what enters and leaves is called the cell membrane. It acts as a barrier to regulate the passage of molecules and ions in and out of the cell.
The mechanism that prevents sodium ions from building up inside the cell is called?
The sodium-potassium pump is the mechanism that prevents sodium ions from building up inside the cell. This pump actively transports sodium ions out of the cell and potassium ions into the cell, maintaining the appropriate ion balance.
The tough outer support of a plant cell is the?
its called the Cuticle but that's on leaves not the plant its self
When sodium is pumped out of a nerve cell what is it called?
Efflux via active transport
What does the Na1 Ka1ATPase transport sodium and potassium into a cell sodium and potassium out of a cell sodium into cell potassium out of cell sodium out of cell potassium in ATP?
NaKATPase transports 3 K ions into the cell and takes only two Na ions out of it.
What is the green organelles called from elodea leaves?
they are called chloroplasts and they help to preform photosynthesis in the plant cell.
What gives leaves their green colors?
Cell parts called chloroplasts are present in the plant cell. Chloroplast contains a pigment known as chlorophyllwhich imparts green colour to the leaves.

Process by which ATP is used to move sodium ions out of the cell and potassium ions back into the cell?
This process is called the sodium-potassium pump. It uses ATP to pump sodium ions out of the cell against their concentration gradient and pump potassium ions back into the cell against their concentration gradient. This mechanism helps maintain the appropriate balance of sodium and potassium ions inside and outside the cell, which is crucial for cellular functions such as nerve transmission and muscle contraction.
