Why Sodium and potassium ion can only cross in axon membrane through protein channel explain why?
At rest sodium in the outside and potassium on the inside as action potential propagate along the axon, depolirization happens and sodium channel opens and allow sodium ions to flood into the neurone. A wave of deporization spread along the neuron, the neuron membrane contain specialised protein called channels. the channel from pore.

What is a gated protein?
A gated protein is a protein that can open or close a gate in a cell membrane, regulating the flow of ions or molecules across the membrane. This process allows for the selective transport of specific substances in and out of cells, contributing to cellular function and signaling.
Can sodium still enter a membrane if ATP is not present to activate the sodium potassium pump?
Yes, sodium can still passively diffuse into the cell through leak channels even if the sodium-potassium pump is not active. The sodium-potassium pump primarily works to maintain the concentration gradient of sodium ions by actively transporting them out of the cell, but without ATP, this process would eventually fail.
Which food group is rich in calcium vitamin d potassium and protein?
milk,banana,seafoods just eat fruits and also vegetables to keep u healthy and also proper exercise :)
What is membrane permeability?
Membrane permeability refers to the ability of molecules, substances, etc. to pass through the membrane. For example, the cell membrane is referred to as 'semi-permeable' because it allows some molecules (such as water) to enter, and stops other molecules (such as sodium ions) from passing through the membrane. If these want to get into the cell, they must then rely on proteins in the cell membrane to let them in.
Where potassium digested?
Potassium is essential for protein synthasis and for the conversion of blood sugar into glycogen. It activates a number of enzymes, particularly those concerned with energy production. Potassium is absorbed from the diet and does not need any specific mechanism and takes place in the small intestine as long as the concentration in the gut is higher that in the blood. Some potassium can be excreted in sweat. The kidneys are the main regulators Potassium is not digested at all, because it is an element and therefore can not be decomposed into simpler substances by digestion or any other chemical process.
Is a protein that forms an ion channel through a membrane is most likely to be a peripheral protein a trans membrane protein a phospholipid an enzyme or an entirely outside the phospholipid?
A protein that forms an ion channel through a membrane is most likely to be a transmembrane protein. Transmembrane proteins span the lipid bilayer, allowing them to create channels for ions to pass through the membrane. Peripheral proteins are typically found on the surface of the membrane and do not form channels.
Is the sodium potassium pump a carrier protein?
Yes, the sodium-potassium pump is a type of carrier protein that helps transport sodium and potassium ions across the cell membrane.
How does facilitated diffusion occur through a protein channel?
Facilitated diffusion occurs through a protein channel by allowing specific molecules to pass through the cell membrane with the help of a protein channel. The protein channel acts as a tunnel that facilitates the movement of molecules that are too large or polar to pass through the membrane on their own. The molecules bind to the protein channel, which changes shape to allow them to pass through, ultimately helping them move across the membrane.
What protein is sodium potassium?
Sodium-potassium ATPase is a membrane protein that helps maintain the sodium and potassium balance in cells by pumping three sodium ions out of the cell for every two potassium ions pumped in.
What type of transport protein is a sodium potassium pump?
It is a carrier protein
What happens if a molecule is too large to go through a membrane?
The molecule will be transported across the membrane by way of a transport protein or protein channel.
A pore in a cell membrane through witch ions can pass?
Not necessarily. Normally, ions are not small enough to pass through, so they are usually assisted by integrated proteins. However, certain ions such as potassium may sometimes "leak" into or out of the cell membrane due to concentration gradient.
What is a membrane protein that allows specific charged molecules to pass through from one side of the membrane to another?
Ion channel proteins are membrane proteins that allow specific charged ions, such as sodium, potassium, or calcium, to pass through from one side of the membrane to another. They play a critical role in maintaining cell function and communication.
Does facilitated diffusion require a carrier or channel protein for the movement of molecules across the cell membrane?
Yes, facilitated diffusion requires a carrier or channel protein for the movement of molecules across the cell membrane.
What is difference between Na gate and Na pump?
The Na gate is a channel protein on the cell membrane that allows sodium ions to pass through, contributing to the generation of action potentials. The Na pump, or sodium-potassium pump, is an active transport protein that maintains the concentration gradient of sodium and potassium ions across the cell membrane by pumping sodium out of the cell and potassium into the cell.
What channel can help move things across the membrane?
Ion channels facilitate the movement of ions across the membrane. These protein channels create a passageway for specific ions to move down their concentration gradient, facilitating processes such as nerve signaling and muscle contractions.
What is a large protein in the cell membrane that transports a specific ion?
Ion channel
