What type of transport mechanism goes against the concentration gradient?
Active transport is the type of transport mechanism that goes against the concentration gradient.
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.
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.
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.
Are symporters active or passive in their transport mechanism?
Symporters are active transport mechanisms that move molecules across a cell membrane using energy from ATP or an electrochemical gradient.
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 type of transport mechanism goes against the concentration gradient?
Active transport is the type of transport mechanism that goes against the concentration gradient.
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.
What transport mechanism is involved in the process in providing nutrients to a fetus?
transport absortion
What do All plants and animals have mechanism that?
Transport Nutrients
What are the difference between transport and communication?
what is difference between communication and transport
What Transport mechanism is used to remove glucose filtrate the enery needed for that purpose?
Active Transport
What is the significance of active transport in a living cell?
It maintains the cell's chemical environment.
Is the transport mechanism in the model cell passive or active?
passive
