What is a matter
Any kind of active transport.
Osmosis is the membrane activity that does not require the expenditure of energy by the cell. It does not require any input of energy.
Sodium ions moving out of the cell
active transport reguire energy.
They require less energy as they do not do much work compared to teenagers. They should have less energy intake and less energy expenditure.
The movement of water across the plasma membrane is called osmosis. Water moves from where it is in higher concentration to where it is in lower concentration. Osmosis is a type of passive transport and does not require any energy expenditure by the cell.
passive transport
thinking, dreaming require energy
Any movement of molecules into or out of a cell without the expenditure of energy is called diffusion. If the molecule uses special channels to diffuse through the membrane (again, not expending energy), it is called facilitated diffusion.
Passive Transport, doesn't require energy.
Passive transport... the opposite of active transport.
