What process changes the shape of transport proteins when a particle binds with it?
The process that changes the shape of transport proteins when a particle binds to it is called conformational change. This change in shape allows the protein to either open a channel for the particle to pass through or undergo a rotational movement to transfer the particle across the membrane.
Does osmosis require a membrane-bound carrier for transport?
No, osmosis does not require a membrane-bound carrier for transport. Osmosis is the passive movement of water molecules across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration. The process occurs spontaneously and does not require carrier proteins.
Does facilitated diffusion require a transport protein for the movement of molecules across the cell membrane?
Yes, facilitated diffusion does require a transport protein for the movement of molecules across the cell membrane.
Facilitated diffusion and active transport?
Facilitated diffusion is the passive transport of molecules across a membrane with the help of transport proteins. This process occurs down the concentration gradient and does not require energy. In contrast, active transport requires energy to move molecules against their concentration gradient through specific transport proteins.
Does facilitated diffusion require a carrier or channel protein for the movement of molecules across the cell membrane?
Yes, facilitated diffusion requires a carrier or channel protein for the movement of molecules across the cell membrane.
What are the types of membrane transport across the cell membrane require a protein carrier?
The brain
What process changes the shape of transport proteins when a particle binds with it?

Does active transport require a membrane?
Yes, active transport requires a membrane because it involves the movement of molecules or ions against their concentration gradient, which requires energy expenditure. This process is facilitated by specific transport proteins embedded within the membrane.
Does osmosis require a membrane-bound carrier for transport?
No, osmosis does not require a membrane-bound carrier for transport. Osmosis is the passive movement of water molecules across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration. The process occurs spontaneously and does not require carrier proteins.
Does facilitated diffusion require a transport protein for the movement of molecules across the cell membrane?
Yes, facilitated diffusion does require a transport protein for the movement of molecules across the cell membrane.
What is carrier-assisted transport?
Carrier-assisted transport is a mechanism in which a carrier molecule assists in the movement of a substance across a biological membrane. The carrier molecule can bind to the substance and facilitate its transport across the membrane. This process is typically passive and does not require energy input from the cell.
Facilitated diffusion and active transport?
Facilitated diffusion is the passive transport of molecules across a membrane with the help of transport proteins. This process occurs down the concentration gradient and does not require energy. In contrast, active transport requires energy to move molecules against their concentration gradient through specific transport proteins.
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 facilitated diffusion require a carrier or channel protein for the movement of molecules across the cell membrane?
Yes, facilitated diffusion requires a carrier or channel protein for the movement of molecules across the cell membrane.
Do filtration requires a membrane-bound carrier for transport?
No, filtration does not require a membrane-bound carrier for transport. Filtration is a passive process that relies on pressure gradients to separate particles based on size. It does not involve specific carriers to transport molecules.
Are carrier proteins active or passive transport?
Carrier proteins facilitate active transport by moving molecules or ions across a cell membrane against their concentration gradient. They require energy in the form of ATP to transport substances across the membrane.
Is carrier proteins passive transport or active transport?
Carrier proteins can use active or passive transport depending on what type of carrier protein it is (meaning what the protein transports). The form of passive transport that they use is facilitated diffusion. An example of active transport is the Sodium Potassium pump. Active transport requires ATP. Facilitated diffusion is used to transport polar molecules and ions that cannot directly cross the cell membrane. Facilitated diffusion doesn't require energy.
