Depolarization would occur.....a-sodium cations leave the cell b-potassium cations leave the cell c--chloride anions enter the cell d-calcium cations enter the cell?

In a polarized cell membrane there are an excess of sodium cations outside the cell and a relative abundance of potassium cations inside the cell. When a cell depolarizes, sodium ions rush into the cell causing the interior surface of the cell membrane to become slightly more positive, i.e. depolarized. When this happens it triggers potassium channels to open allowing potassium ions to flow out repolarizing the cell. While not completely correct, the best answer of your choices here would be b - potassium cations leave the cell.


What chemicals enter and leave the axon at the Nodes of Ranvier?

Sodium and potassium ions enter and leave the axon at the nodes of Ranvier. Sodium ions enter the axon to depolarize the cell, while potassium ions leave the axon to repolarize the cell and reset its resting potential.


What is the the method by which large particles and macromolecules enter the cell by an infolding of the plasma membrane?

The method by which large particles and macromolecules enter the cell by an infolding of the plasma membrane is called endocytosis. This process involves the formation of vesicles that engulf the molecules and bring them into the cell. Endocytosis includes phagocytosis for solid particles and pinocytosis for liquid molecules.


What concentration gradients are established and maintained by the sodium-potassium pump?

high Na+ concentration in the extracellular fluid; high K+ concentration in the cytoplasm


Do most animal cell membranes have proteins that pump sodium ions out of the cell and potassium ions into the cell?

Yes, most animal cell membranes have protein pumps known as sodium-potassium pumps that actively transport sodium ions out of the cell and potassium ions into the cell. This helps maintain the cell's electrochemical gradient essential for various cellular functions.

How do potassium ions enter carrot cells?

Potassium ions enter carrot cells through protein channels called potassium transporters. These transporters are embedded in the cell membrane and facilitate the movement of potassium ions from areas of high concentration to areas of low concentration, helping to maintain the electrochemical balance within the cell.


What is a passive method by which glucose molecules enter cells?

Passive diffusion is a method by which glucose molecules enter cells. Glucose can diffuse through the cell membrane down its concentration gradient without the need for energy input from the cell.


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.

The concentration of potassium ions inside the cell is usually what?

The concentration of potassium ions inside the cell is typically higher than it is outside the cell. This concentration gradient is maintained by the sodium-potassium pump, which actively transports potassium ions into the cell. This imbalance in potassium concentration is important for various cellular processes, such as maintaining the cell's resting membrane potential.


What concentration gradients are established and maintained by the sodium-potassium pump?

high Na+ concentration in the extracellular fluid; high K+ concentration in the cytoplasm

How does potassium and sodium move into the cell?

Potassium enters the cell through potassium channels that open in response to changes in membrane potential. Sodium enters the cell through sodium-potassium pumps, which actively transport sodium ions against their concentration gradient.
