What is a carrier protein?
A carrier protein is a type of protein that helps transport specific molecules across cell membranes. These proteins bind to molecules on one side of the membrane and release them on the other side, facilitating their movement into or out of cells. Carrier proteins play a crucial role in maintaining cellular function by regulating the transport of essential molecules.
Is the sodium potassium pump a carrier protein?
Yes, the sodium-potassium pump is a type of carrier protein that helps transport sodium and potassium ions across the cell membrane.
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 does a carrier protein do in the process of transporting molecules across a cell membrane?
A carrier protein helps transport molecules across a cell membrane by binding to specific molecules and changing shape to move them across the membrane.
Primary active transport involves a conformational change in the carrier protein The most immediate stimulus for this is?
The most immediate stimulus for the conformational change in the carrier protein in primary active transport is the binding of ATP or another source of chemical energy. This energy is used to pump molecules against their concentration gradient.
Is the sodium potassium pump a carrier protein?
the carrier protein of Na-k pump is an ion carrier protein and the pump cannot be termed as the carrier protein its a biochemical phenomenon

The passive form of a carrier protein is called?
Protein channels.
How does a protein transport substances across a cell membrane?
carrier protein
What protein helps things across a cell membrane?
Carrier Protein
What changes occur to a carrier protein once it binds to its target molecules?
the carrier protein changes shape to release the molecule inside of a cell
Through what type of proteins does active transport occur?
Active transport occurs through carrier proteins that pump molecules against their concentration gradient using energy from ATP. These carrier proteins undergo conformational changes to transport molecules across the cell membrane.
Is the sodium potassium pump a carrier protein?
Yes, the sodium-potassium pump is a type of carrier protein that helps transport sodium and potassium ions across the cell membrane.
How do solute molecules pass through the membrane?
The solute molecule, when passing through the membrane passively using a carrier protein, is called the substrate. The solute, or substrate will bind to the carrier protein from the outside, the carrier protein changes conformation, and the substrate is exposed to the inside of the membrane.
Are both zinc and iron transported in the blood by a fat carrier?
Zinc is primarily transported in the blood by a protein carrier called albumin, while iron is typically transported by a protein called transferrin. These carriers help maintain the proper levels of these minerals in the blood and deliver them to the cells that need them.
What carrier protein takes sugar into a cell with out energy?
osmosis
Protein used to transport specific substances?
carrier proteins
