Which form of transport across the cell membrane does not require energy but a carrier protein?
Facilitated transport.
Does Osmosis require ATP?
No, osmosis is a form of passive transport.
What process changes the shape of transport proteins when a particle binds with it?
Carrier Proteins. Some don't require ATP (Facillitated transport) and some do require ATP (Active transport) to change shape.
Why is osmosis an example of passive transport and not active transport?
passive transport does not require energy eg. diffusion and osmosis. Therefore, osmosis is a passive transport. Active transport requires energy eg. a molecule going from a low concentration from a high concentration.
What are a series of carrier proteins?
Active transport involves carrier proteins. Carrier proteins bind themselves to particles and transport them to highly concentrated areas within a cell.Facilitated diffusion and active transport require carrier proteins.
Which form of transport across the cell membrane does not require energy but a carrier protein?
Facilitated transport.
Does osmosis require a carrier?
NO. Osmosis( by definition) is the DIFFUSION of water from a high concentration gradient to a low concentration gradient across a semipermeable membrane. As diffusion is a form of passive transport, it doesnt require a carrier
Does Osmosis require ATP?
No, osmosis is a form of passive transport.

Carrier Proteins. Some don't require ATP (Facillitated transport) and some do require ATP (Active transport) to change shape.
Are diffusion and osmosis passive or active transports?
Diffusion and osmosis are passive and do not require energy.
Why is osmosis an example of passive transport and not active transport?
passive transport does not require energy eg. diffusion and osmosis. Therefore, osmosis is a passive transport. Active transport requires energy eg. a molecule going from a low concentration from a high concentration.
What is the difference between active transport and osmosis?
Osmosis is the diffusion of water across a membrane, and does not require the input of energy. Active transport requires energy input.
What are a series of carrier proteins?
Active transport involves carrier proteins. Carrier proteins bind themselves to particles and transport them to highly concentrated areas within a cell.Facilitated diffusion and active transport require carrier proteins.
Diffusion and Osmosis are passive transport mechanisms meaning they do not require?
They do not require energy, which is often in the form of ATP.
How is diffusion different from active transport?
active transport is different from diffusion. active transport has to do with the movement of chemical substance through a gradient of concentration. diffusion has to do with requiring the expenditure of energy
Carrier proteins do not require energy to transport amino acids into a cell?
diffusion
Is osmosis of active transport or passive transport?
Osmosis does not require ATP so it is a passive transport.Osmosis is a form of passive transport. Water molecules are small enough to move freely across the plasma membrane without the use of cellular energy.
