Active transport mechanism which maintains the potential difference of the membrane?
The sodium-potassium pump is a primary active transport mechanism that helps maintain the potential difference across the cell membrane by actively pumping sodium ions out of the cell and potassium ions into the cell against their concentration gradients. This process requires energy in the form of ATP and plays a crucial role in regulating cell volume and transmitting nerve impulses.

Which transport mechanism is most probably functioning in the intestinal cells?
The primary transport mechanism in intestinal cells is active transport, utilizing carrier proteins to move nutrients against a concentration gradient into the cell. This mechanism allows for the absorption of essential nutrients like sugars and amino acids from the intestine into the bloodstream for distribution throughout the body.
In the absence of stimuli all cells in the body maintain a potential difference across the semipermeable membrane in which the inside of the cell is negatively charged in comparison to the outside?
This resting membrane potential is typically around -70mV in neurons, maintained by the unequal distribution of ions across the membrane. Sodium-potassium pumps actively transport ions to establish this potential difference. It is crucial for processes like signal propagation and cellular function in excitable cells.
What is a brief description of the action of the sodium-potassium pump?
The sodium-potassium pump is a process that maintains the cell's resting membrane potential by pumping out three sodium ions while simultaneously pumping in two potassium ions. This active transport mechanism requires ATP as an energy source and helps to regulate cell volume and maintain the balance of ions inside and outside the cell.
What are the example of active transport?
Examples of active transport include the sodium-potassium pump, which maintains the concentration gradients of sodium and potassium ions across cell membranes, and the transport of glucose by glucose transporters in the intestine and kidney. These processes require energy in the form of ATP to move molecules against their concentration gradients.
What mechanism does a cell use to move small potassium molecules into the cell against the concentration gradient?
Cells use active transport mechanisms, such as the sodium-potassium pump, to move potassium ions against their concentration gradient into the cell. This pump utilizes the energy from ATP hydrolysis to actively transport sodium out of the cell and potassium into the cell, maintaining the concentration gradient for potassium.
Which transport mechanism might be used to prevent the movement of sodium ions intovthe cell when it is at resting potential?
Passive Transport
What is the transport mechanism using ATP?
bike
What transport mechanism might be used to prevent the movement of sodium ions into the cell when it is at resting potential?
One transport mechanism that can prevent the movement of sodium ions into the cell when it is at resting potential is the sodium-potassium pump. This pump actively transports 3 sodium ions out of the cell and 2 potassium ions into the cell, maintaining the concentration gradient necessary for resting potential.
The cellular transport mechanism that depends upon blood pressure?
Passive transport is the cellular transport mechanism. This all depends on the blood pressure.
What transport mechanism is used to prevent to movement of sodium ions into the cell when it is at resting potential?
Passive transport - i.e., "leaky conductance" provided by NLCN channels for example.
