Answer: Through Diffusion Process
Step-by-step explanation:
Diffusion is the net movement of molecules from areas of higher concentration to areas of lower concentration (at constant temperature and pressure). It does not require energy and is the main mechanism for the movement of molecules in cells. Osmosis is the diffusion of water across a selectively permeable membrane.
The transport of ions and hydrophilic molecules across the cell membrane is facilitated by two major classes of highly specific protein systems: channels and transporters. Channels form conduits through which substances diffuse without requiring energy. The opening of a channel occurs when chemical or electrical stimuli induce conformational changes in the protein. Ion transport in channels is driven by chemical or electrochemical potential gradients. Transporters have sites to which molecules to be transported bind. The transport of these molecules can be driven by chemical or electrochemical potential gradients or with the use of primary energy sources, such as chemical energy, light energy, etc.
