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.
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.
Cellular transport mechanism that depends upon transporters or carrier enzymes in the cell membrane is?
Protein is the cell that moves mechanism the depends on movement. This cell carries enzymes in the membrane.
Is diffusion an active mechanism?
False
What is pulmonary respiration?
The mechanism of pulmonary respiration: It includes breathing movement, exchange of gases, in lungs, transport of gases by blood and exchange of gase by tissue.
Which transport process is the main mechanism of the movement of most macromolecules by body cells?
receptor-mediated endocytosis
What is hypotonic transport?
Hypotonic transport is the movement of solutes across a membrane using a solution that has a lower solute concentration compared to the cell's cytoplasm. This can lead to the swelling and potential bursting of the cell if the transport is not regulated properly.
What is Ambipolar Transport Mechanism?
Ambipolar transport is a mechanism that allows for the movement of both positive and negative charges in a material, such as in semiconductors or plasmas. This allows for more efficient control of charge carriers and is essential for creating certain electronic devices like solar cells and transistors. Ambipolar transport is important for balancing charge carriers and ensuring proper device functionality.
What is carrier-assisted transport?
Carrier-assisted transport is a mechanism in which a carrier molecule assists in the movement of a substance across a biological membrane. The carrier molecule can bind to the substance and facilitate its transport across the membrane. This process is typically passive and does not require energy input from 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 does a passive transport and an active transport have in common?
Movement of particles .
Is the mineral movement into plant root passive transport or active transport?
active transport
