What else can I help you with?
What is made from lipids and diffuse freely into cells through the plasma?
protiens
What substances diffuse into and what diffusen out of cells?
The substances flow from high concentration to low concentration through channels found in the cell membrane. Basically like a bridge.
Human lungs are made up of very thin cells what processes is aided by the thin cells?
The thin cells in human lungs aid in the process of gas exchange. This allows oxygen from the air to diffuse into the bloodstream, while carbon dioxide is released from the blood into the air in the lungs.
Even though the cocentration of salt is higher in some gland-cells than in blood-cells the gland-cells can still take salt out of blood-cells this is an example of?
Active transport, specifically sodium-potassium pump. This pump uses energy to move sodium out of the cell and potassium into the cell against their concentration gradients. This process allows gland cells to maintain a higher concentration of salt internally despite the higher concentration in the blood.
How do sodium potassium pumps work to maintain the balance of ions within cells?
Sodium-potassium pumps use energy to move sodium ions out of cells and potassium ions into cells, helping to maintain the balance of ions. This process is crucial for cell function and overall health.
How does the sodium potassium pump help maintian fluid balance?
The sodium potassium pump is constantly a work in each cell of the body to keep sodium and potassium levels in cell fluids even. This pump allows sodium ions which are abundant outside of the cell, to diffuse into the cell, and potassium, which is abundant inside the cell, to diffuse to outside the cell. If this process were to cease, sodium ions would build up inside your cells, which would attract water and ultimately cause the cell to explode.
What type of channel does sodium and potassium use to diffuse across the plasma membrane of all cells?
Sodium and potassium diffuse across the plasma membrane of cells through ion channels called voltage-gated channels. These channels open and close in response to changes in membrane potential, allowing sodium and potassium ions to flow down their electrochemical gradients.
Period during which potassium ions diffuse out of the neuron's membrane?
sodium-potassium pump
What lets substances like food and oxygen diffuse into body cells?
The semi-permeable membrane in cells. Allows some substances to go through and not others.
Will potassium permanganate or methylene blue diffuse faster?
Methylene blue will diffuse faster than potassium permanganate. Methylene blue has a smaller molecular size and a higher diffusion rate compared to potassium permanganate.
How does dextrose and insulin lower potassium?
The glucose with the help of insulin opens the cells and allows the Potassium ion to go inside the cells ( which is normally intracellular) thus, lowering the serum Potassium level ( in the blood). ☼ R.N. Intensive nurse. Phils.
What walls does the oxygen and nutrients diffuse?
Oxygen and nutrients diffuse across the walls of capillaries in the bloodstream into tissues and cells in the body. This allows for the delivery of essential molecules to support cellular function and metabolism.
What is made from lipids and diffuse freely into cells through the plasma?
protiens
What things diffuse into?
The molecules of food and oxygen diffuse into cells. oh and btfw co2 and waste chemicals diffuse ut of cells. im in year 3
What substances diffuse into and what diffusen out of cells?
The substances flow from high concentration to low concentration through channels found in the cell membrane. Basically like a bridge.
Where does potassium diffuse to after an action potential is propagated?
Out of the cell into the tissue fluid.
What is relative permeability of potassium ions in unstimulated cells?
The relative permeability of potassium ions in unstimulated cells is generally high, as potassium ions play a key role in maintaining the cell's resting membrane potential. This allows for potassium ions to move across the cell membrane more easily than other ions.
