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 is the method of transport for the movement of sodium ions into the cell and the potassium ions between the red blood cell and the plasma?
By facilitated diffusion and active transport
What is the the method by which large particles and macromolecules enter the cell by an infolding of the plasma membrane?
Endocytosis
Do sodium ions move to inside of neuron in a nerve impulse?
No. Three sodium ions are pumped out of the neuron by the sodium-potassium pump and two potassium ions enter the cell. This way you maintain a slightly negative charge just inside the cell membrane.
Which electrolyte flows into the cell to initiate depolarization?
potassium The answer of potassium is dead wrong. Sodium is the electrolyte that flows into the cell to initiate depolarization. Potassium flows into the cell during repolarization.
What ions enter the muscle cell during action potential generation?
sodium and potassium

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 answer to Excel explain how to enter the formula C4 plus B5 plus D2 in cell D3 using the point-and-click method?
You will enter the formula by chosing summation and then clicking the cells, while on cell d3, click enter.
Do sodium ions move to inside of neuron in a nerve impulse?
No. Three sodium ions are pumped out of the neuron by the sodium-potassium pump and two potassium ions enter the cell. This way you maintain a slightly negative charge just inside the cell membrane.
The concentration of potassium ions inside the cell is usually what?
The concentration of potassium ions inside the cell is usually MORE THEN then the concentration of potassium.
Which electrolyte flows into the cell to initiate depolarization?
potassium The answer of potassium is dead wrong. Sodium is the electrolyte that flows into the cell to initiate depolarization. Potassium flows into the cell during repolarization.
What is the principle of the cyanmethemoglobin method?
Colorimetric method where blood is mixed with solution containing potassium ferricyanide and potassium cyanide. Potassium ferricyanide oxidizes iron to form methemoglobin and potassium cyanide then combines with methemoglobin to form cyanmethemoglobin.
The part of the cell that regulates what can enter and leave?
The cell membrane determines what comes in and what goes out. Water goes in and out by osmosis which is a passive method. Others require the help of proteins that act as doorways. These require energy and the method is called active transportation.
What is a brief description of the action of the sodium-potassium pump?
The sodium-potassium pump is a transmembrane protein in a cell membrane. It keeps large concentrations of sodium ions outside the cell, and potassium ions inside the cell. It does this by pumping the sodium ions out, and the potassium ions in.
