What hormone regulates Na plus and K plus ion concentration?
aldosterone
Is the The resting membrane potential is mainly determined by the concentration gradient of K plus inside the cell?
Yes, the resting membrane potential is largely determined by the concentration gradient of potassium ions (K+) inside the cell. This is due to the high permeability of the cell membrane to K+ ions, which allows them to move down their concentration gradient, establishing the negative resting potential.
Which membrane protein is responsible for restoring the original concentration of Na plus and K plus?
The sodium-potassium pump, also known as the Na+/K+-ATPase, is responsible for restoring the original concentration of sodium and potassium ions across the cell membrane. This pump actively transports three sodium ions out of the cell in exchange for two potassium ions pumped into the cell, using ATP energy to maintain the concentration gradients.
The cytoplasm of a certain cell such as a neuron which already has a high concentration of k plus ions can continue to take k plus ions up into the cell this is the result of?
This process is a result of active transport, specifically the action of the sodium-potassium pump. The sodium-potassium pump actively transports potassium ions into the cell against their concentration gradient, utilizing ATP for energy. This maintains the high concentration of potassium ions inside the cell.
Which channel maintains the concentration gradients of ions across a neuronal membrane?
Ion channels, such as sodium-potassium pumps, help maintain concentration gradients of ions across a neuronal membrane. These channels actively transport ions across the membrane, moving them against their concentration gradients to establish and regulate the resting membrane potential.
What hormone regulates Na plus and K plus ion concentration?
aldosterone
What is the concentration of K plus ions in a 0.025 M K2CO3 solution assuming complete dissociation?
The concentration of K+ ions in a 0.025 M K2CO3 solution would be 0.050 M because each formula unit of K2CO3 produces two K+ ions when it dissociates completely in solution.
What ions is in high concentration inside the neuron?
Potassium ions (K+) are found in high concentration inside the neuron compared to outside. This concentration gradient is maintained by the sodium-potassium pump.
What is the molar concentration of K ions in a 0.0175 M solution of potassium phosphate?
0,052 moles

The ph of lemon juice at 298 k is found to be 2.32 what is the concentration oh H3O plus ions in the solution?
The concentration of H3O+ ions can be calculated using the formula pH = -log[H3O+]. Rearrange the formula to get [H3O+] = 10^(-pH). Plugging in the pH value of 2.32 gives a concentration of H3O+ ions of approximately 4.63 x 10^(-3) M.
Which channel maintains the concentration gradients of ions across a neuronal membrane?
Ion channels, such as sodium-potassium pumps, help maintain concentration gradients of ions across a neuronal membrane. These channels actively transport ions across the membrane, moving them against their concentration gradients to establish and regulate the resting membrane potential.
What is osmotic alterations?
Osmotic alterations can be defined as the fragility of the red blood cells in hypo and hyperthyroid patients. Changes in the concentration of the thyroid hormone can affect Na+K+ATPase number and activity and the phpspholipid composition of the cell membranes.
In the Na K pump where do the ions go?
The Na-K pump actively transports three sodium ions out of the cell and two potassium ions into the cell against their respective concentration gradients. The sodium ions are pumped out of the cell and the potassium ions are pumped into the cell by the action of ATPase on the pump.
What would happen to the equilibrium potential of Na if you change the concentration of K inside the cell?
The equilibrium potential of sodium (Na) is primarily determined by the concentration of Na ions inside and outside the cell, as described by the Nernst equation. Changing the concentration of potassium (K) inside the cell does not directly affect the equilibrium potential of Na. However, alterations in K concentration can influence the overall membrane potential and the activity of sodium channels, which may indirectly affect the dynamics of Na influx during action potentials. Thus, while the Na equilibrium potential remains unchanged, the cell's excitability and response to stimuli could be affected.
