A molecule that is too large or charged would be unable to diffuse through a cell membrane.
Protons are unable to diffuse through the inner mitochondrial membrane because the membrane contains proteins called ATP synthase that provide a specific pathway for protons to pass through. This selective permeability allows protons to be utilized by ATP synthase to generate ATP during oxidative phosphorylation.

If a membrane protein were unable to bind to a signaling molecule, it would lead to a disruption in cell signaling pathways. This could result in altered cellular responses, such as improper communication between cells or impaired signaling cascades, leading to dysfunctional physiological processes.
Oxygen is a small, nonpolar molecule that can cross the plasma membrane via simple diffusion. Sodium ions, on the other hand, are charged and larger molecules that cannot easily pass through the hydrophobic interior of the plasma membrane. Sodium must rely on specific transport proteins like ion channels or pumps to cross the membrane.
It allows only certain molecules to pass through.
osmotically active
An impermeable solute is a substance that cannot pass through a semipermeable membrane, such as a cell membrane. This means that the solute is unable to diffuse or move across the membrane and remains on one side of the membrane.
Protons are unable to diffuse through the inner mitochondrial membrane because the membrane contains proteins called ATP synthase that provide a specific pathway for protons to pass through. This selective permeability allows protons to be utilized by ATP synthase to generate ATP during oxidative phosphorylation.
The universal energy molecule of the cell, adenosine triphosphate (ATP) cannot passively diffuse across the cell membranes. Despite its low molecular weight, ATP carries a strong negative charge making it hydrophilic and thus unable to diffuse across the lipophilic cellular membrane.

If a membrane protein is unable to bind to a signaling molecule, it may not be able to transmit the intended signal across the cell membrane. This could result in disrupted cellular communication and potentially lead to improper cell function or response to stimuli.
