What isit called when a molecule moves across a semipermeable membrane into a region of higher concentration?

When a molecule moves to a higher concentration it needs help of a pump. We call this facilitated diffusion. Osmosis only deals with the movement of water.

∙ 13y agoWell, if it's moving into an area of higher concentration (that is, moving against the concentration gradient) that sounds like active transport (but it may go under different names, such as diffusion against the gradient)

Is movement of water from an area of high concentration to an area of low concentration across a?
across semipermeable membrane? That is osmosis, the net movement of water.
What is the definition for osmosis?
# a physical chemistry,cell biology. ------------------------------ Movement of solvent through a semipermeable membrane so as to equalize the concentration of solute across the membrane.
What is the movement of water across a semipermeable membrane from an area of high water concentration to an area of low concentration called?
Osmosis
What are the principal cations in opur body fluids?
Well, considering this isn't even a full sentence, let alone a question, I'll see what I can pull out of it.Diffusion of a substance across a semipermeable membrane is diffusion.Diffusion of a solute across a semipermeable membrane is dialysis.Diffusion of water across a semipermeable membrane is osmosis.Diffusion is a type of passive transport.Osmosis and dialysis are both forms of diffusion.
Movement of substances from higher to lower concentration across a semipermeable membrane that must have a specific protein carrier but no energy expenditure is called?
facilitated diffusion.
What is it when a molecule uses energy to move across a semipermeable membrane?
active transport
What type of molecule movement consist on one way diffusion across a semi permeable membrane?
The movement of molecules across the semipermeable membrane follows the law of diffusion. Thus, the molecules of a substance move from their higher concentration towards their lower concentration by their own kinetic energy.
Is movement of water from an area of high concentration to an area of low concentration across a?
across semipermeable membrane? That is osmosis, the net movement of water.
What is the movement of water across a semipermeable membrane from an area of high water concentration to an area of low water concentration called?
Osmosis
When osmosis occurs specifically which molecule move across a semipermeable membrane?
Osmosis is defined as the passive movement of water molecules from a region of low solute concentration to a region of high solute concentration through a partially permeable membrane; water molecules are thus exhibiting the movement.
What kinds of molecules freely diffuse across a semipermeable membrane?
Water molecules freely diffuse across a semipermeable membrane.
What is osomsis and difusion?
Osmosis is the tendency of a solvent to travel across a semipermeable membrane (Semipermeable membrane- a membrane that allows some molecules to pass through but does not allow other molecules to pass through) into areas of higher solute concentration. Diffusion is the random motion of molecules from an area of high concentration to an area of low concentration.
What is the definition for osmosis?
# a physical chemistry,cell biology. ------------------------------ Movement of solvent through a semipermeable membrane so as to equalize the concentration of solute across the membrane.
Which process allows ions to move across a semipermeable membrane where the concentration of ions is low to where their concentration is even higher?
Active transport BIOLOGY APEX
What is the movement of water across a semipermeable membrane from an area of high water concentration to an area of low concentration called?
Osmosis
What iprocess occurs as water moves from regions of higher concentration to lower across a semipermeable membrane?
Osmosis, which is the diffusion of water.
what is exact definition of osmosis?
Osmosis is the movement of water across a semipermeable membrane from a higher concentration of water to a lower concentration of water without the use of energy.
