What else can I help you with?
What does a carrier protein do in the process of transporting molecules across a cell membrane?
A carrier protein helps transport molecules across a cell membrane by binding to specific molecules and changing shape to move them across the membrane.
What kinds of molecules freely diffuse across a semipermeable membrane?
Water molecules freely diffuse across a semipermeable membrane.
What is the process When proteins help molecules move across the membrane is called?
when proteins help molecules move across the membrane, it it called Facilitated Diffusion
When molecules are moving back and forth across the membrane will they ever stop moving?
Yes, in an isotonic solution the movement of molecules across the membrane will stop.
How do carrier proteins facilitate the passive transport of molecules across a membrane?
Carrier proteins facilitate the passive transport of molecules across a membrane by binding to specific molecules on one side of the membrane and changing shape to transport the molecules across to the other side. This process does not require energy and is driven by the concentration gradient of the molecules.
Does facilitated diffusion require energy for the movement of molecules across the cell membrane?
No, facilitated diffusion does not require energy for the movement of molecules across the cell membrane.
Does facilitated diffusion require energy for the transportation of molecules across the cell membrane?
Facilitated diffusion does not require energy for the transportation of molecules across the cell membrane.
Does facilitated diffusion require energy to transport molecules across the cell membrane?
Facilitated diffusion does not require energy to transport molecules across the cell membrane.
Does passive transport require ATP for the movement of molecules across the cell membrane?
No, passive transport does not require ATP for the movement of molecules across the cell membrane.
What biomolecule helps transport molecules across the membrane?
proteins
What is the equilibrium of solute across a membrane?
The equilibrium of solute across a membrane is reached when the concentration of the solute is the same on both sides of the membrane. This means that the movement of the solute molecules is balanced, with an equal number of molecules moving in and out of the membrane. At equilibrium, there is no net movement of solute across the membrane.
Is the movement of molecules across a membrane down the concentration gradient a passive or active process?
The movement of molecules across a membrane down the concentration gradient is a passive process.
