Respuesta :
The mechanism of ion uptake that would best move sodium from the inside of the cell to the outside is active transport.
What do you mean by Ion uptake?
Ion uptake may be defined as the process of movement of ions from one side of the membrane to the other.
Active transport helps in the movement of ions against the concentration gradient. It also requires energy. The active transport of small molecules or ions across a cell membrane is generally carried out by transport proteins that are found in the membrane.
Therefore, the mechanism of ion uptake that would best move sodium from the inside of the cell to the outside is active transport.
