Homeostasis is the process of maintaining a cell’s environment. This includes the regulation of sodium ion (Na+) concentration within the cytoplasm. If too much Na+ is inside a cell, how can the concentration be changed?
More Na+ ions will enter the cell through the plasma membrane.
Excess Na+ ions will leave the cell via osmosis.
Excess Na+ ions will be transported out through membrane protein channels.
More Na+ ions will be transported in through membrane protein channels.

transport protein
cytoskeleton
