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.


Carrier molecules in the plasma membrane are only required for active transport?

Carrier molecules in the plasma membrane are actually used for both active and passive transport of molecules. In active transport, carrier proteins use energy to move molecules against their concentration gradient, while in passive transport, carrier proteins facilitate the movement of molecules down their concentration gradient without the need for energy input.


How is facilitated diffusion similar to both passive transport and active transport?

AnswerBoth serve to transport molecules across cell membranes and both make use of proteins embedded in cell membrane in order to move these molecules.How_are_facilitated_diffusion_and_Active_transport_similar


Does simple diffusion require transport proteins?

No, simple diffusion does not require transport proteins. It is a passive process where molecules move from an area of higher concentration to an area of lower concentration directly through the lipid bilayer of the cell membrane. Transport proteins are involved in facilitated diffusion and active transport.


Transport proteins play a role in both?

Transport proteins play a critical role in facilitating the movement of molecules across biological membranes, such as ions, nutrients, and waste products. They help maintain cellular homeostasis by regulating the flow of substances into and out of the cell. Transport proteins can be passive (facilitated diffusion) or active (requiring energy).

Is a carrier protein an active transport or a passive transport?

They are used in both, in passive the molecules move in , then change the shape then leave and the entering and leaving are both by diffusion. in active transport molecules move in by diffusion, change the shape of the carrier protein, then because theyre moving into the cell where the molecule is in higher concentration energy is required to push the molecules out of the carrier proteins, this energy comes from ATP which is supplied to the carrier proteins.

How is active transport different from passive transport, and what are two ways in which they contrast in terms of their mechanisms?

Active transport and passive transport are two methods by which substances move across cell membranes. Active transport requires energy input from the cell, usually in the form of ATP, to move molecules against their concentration gradient. In contrast, passive transport does not require energy and relies on the natural movement of molecules from areas of high concentration to low concentration. One way in which active and passive transport contrast in terms of their mechanisms is that active transport uses specific carrier proteins to transport molecules, while passive transport can occur through simple diffusion or facilitated diffusion. Another difference is that active transport can move molecules in both directions across the membrane, while passive transport typically only moves molecules in one direction.


Is water an active or passive transport?

Water can use both passive and active transport mechanisms. Passive transport involves movement of water molecules across a membrane without the need for energy, while active transport involves the use of energy to move water molecules against their concentration gradient.


Do passive transport mechanisms use integral proteins to move substances through membranes?

Yes they may. Passive or Active can both use integral proteins to facilitate transport. When the substances are transported from low to high concentration it requires additional energy (i.e. active transport); while passive transport move molecules from high concentration to low and do not need additional energy (passive transport). Integral proteins are membrane proteins that have transmembrane domain, but whether it will need energy (ATP, photons or conc. gradient) to change from inactive form to active form depends on the substance that it is transporting.


Are diffusion and osmosis passive or active transports?

Diffusion and osmosis are passive and do not require energy.
