What else can I help you with?
Why aren't protons able to diffuse through the inner mitochondrial 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.
Why can oxygen diffuse across a cell but a protein cannot?
Oxygen is much smaller than a protein.proteins are too largeDifference in size
What will happen if a membrane protein were unable to bind to a signaling molecule?
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.
Why can oxygen easily cross the plasma membrane but sodium ions are unable to cross the plasma membrane?
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.
What is meant by cell membrane is semipermeable?
It allows only certain molecules to pass through.
If a substance is unable to diffuse across a membrane we say the membrane is?
osmotically active
What is an impermeable solute?
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.
Why aren't protons able to diffuse through the inner mitochondrial 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.
Can ATP passively diffuse across cell membrane?
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.

What would happen if a membrane protein we're unable to bind to a signaling molecule?
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.
What would would happen if a membrane protein was unable to a signaling molecule?
Messages would not be sent to the inside of the cell.
