Answer:
dissolved or soluble
Explanation:
soluble substances can move into or out of cells by diffusion
Dissolved or soluble substances can move into or out of cells by diffusion.
Diffusion is the type of transport in general that soluble substances have without charge, the difference in concentration is the main responsible for the flow.
A substance is said to undergo diffusion when it passes through a membrane from a site where the chemical potential (concentration) is higher to a site where the chemical potential is lower, without requiring any aid for passage.
In other words, diffusion is the passage through a membrane in favor of its concentration gradient, without requiring the presence of molecular membrane mechanisms (transporters or carriers).
For the diffusion to happen, we must take into account 3 important factors:
- Size: the molecules must have a size equal to or smaller than the pores of the membrane so that they can pass without problem.
- Electrostatic charge: the molecules must have the opposite electrostatic charge to that of the membrane or simply have a neutral charge.
- Solubility: if the molecules are larger than the pores, they must be dissolved in a solution, reducing their size and thus can enter the cell through the membrane.
Therefore, we can conclude that dissolved or soluble substances can move into or out of cells by diffusion, where simple diffusion is responsible for transporting soluble substances without charge through the lipid bilayer.
