Respuesta :
Small ions are least likely to diffuse through the phospholipid bi layer of a cell membrane.
Answer: Option D
Explanation:
The structure as well the chemical composition of the bi layer is involved in the determination of entry and exit of molecules across the membrane. This membrane considers the size and charge of the substance as factors to allow for diffusion.
The layer is highly penetrable to non-polar (fat-solvent) particles. The permeability of the layer to polar (water dissoluble) atoms is extremely low, and penetrability to charged sub-atomic species such as ions are very low despite their size.
Thus it can be inferred that hydrophobic molecules regardless of their size has a high rate of diffusion whereas ions regardless of their size have a low rate of diffusion.
The option that is least likely to diffuse through the phospholipid bilayer of a cell membrane is D. Small ions.
- The cell membrane refers to the biological membrane that's vital in the protection of the cells from the environment.
- The chemical composition of the bilayer is vital in the determination of the passage of molecules across the membrane.
- It should be noted that the layer is highly penetrable to fat-solvent particles. Therefore, it should be noted that the least likely to diffuse through the phospholipid bilayer of a cell membrane is the small ions.
