Why does NaCl not require a transport protein for diffusion?
NaCl can diffuse freely across cell membranes through ion channels or transporters that allow for passive movement down its concentration gradient. As a small and simple molecule, NaCl does not require a specific transport protein for diffusion like larger or more complex molecules.
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 are the types of membrane transport across the cell membrane require a protein carrier?
The brain
Do ions require a transport protein?
Not in blood, ions are usually quite water soluble.
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.
what two methods of transport require a transport protein?
Two methods of transport that require a transport protein are facilitated diffusion and active transport. Facilitated diffusion involves the movement of molecules across a cell membrane through specific transport proteins, down their concentration gradient without the use of energy. Active transport, on the other hand, uses transport proteins to move substances against their concentration gradient, requiring energy in the form of ATP.
Did NaCl affect glucose transport?
no it does not
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 nacl effect glucose transport?
No it doesn't.
What types of transport require ATP?
The two types of cell trnsport it Passive Transport and Active Transport. Active Transport does require energy to move into and out of the cell. Passive Transport doesn't require energy to move into and out of the cell. Hope I helped!
What is the difference between facilitated diffusion with the help of a carrier molecule with the help of a transport protein?
Facilitated diffusion is a type of passive transport (does not require energy). It is called facilitated diffusion because it utilises the carrier protein to diffuse through it. Active transport requires energy to pump certain big molecules to cross over and this uses transport protein. Basically, the difference is just the usage of energy.
Do pumps require a protein channel?
Pumps do not require a protein channel; instead, they are specialized proteins that actively transport molecules across cell membranes against their concentration gradient. This process requires energy, usually derived from ATP. In contrast, protein channels facilitate passive transport, allowing molecules to move down their concentration gradient without energy input. Thus, while both pumps and channels are integral to membrane transport, they function differently.
