A specific protein that recognizes certain molecules bringing them across the membrane?
Receptor Protein.
What molecule uses energy to push molecules through the membrane of a cell?
Transport Protein
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.
A special molecule that uses energy to push molecules through a membrane of a cell is called?
Transport protein
What process involves the use of specific carrier molecules?
two processes requiring the use of protein carrier molecules?
How do the roles of protein molecules in diffusion differ and active transport?
== == == == == == == == == ==
What are the protein molecules in a cell membrane that assist in cell transport?
Protein molecules are responsible for membrane transport. In passive transport diffusion is the phenomenon in which molecules flow naturally from areas of high concentration to lower concentrations.
What structure is small nonpolar molecules may pass through this structure but others require a protein channel?
A semipermeable membrane
A specific protein that recognizes certain molecules bringing them across the membrane?
Receptor Protein.
Are proteins necessary to transport oxygen to body?
A protein (hemoglobin) is required to transport Oxygen around the body.
What molecule uses energy to push molecules through the membrane of a cell?
Transport Protein
Why the osmosis involves the movement of molecules via special transport protein?
facilitated diffusion
What is passing of electrons through a series of protein molecules is called?
Electron Transport Chain
What protein recognizes certain molecules bringing them across a membrane?
channel or transport or receptor
What ion channel is a transport protein that?
A protein channel is a transport protein that helps larger molecules, that would otherwise not be able to defuse throw the membrane of a cell, to move in or out of the cell depending on the concentration gradient.
How do you transport proteins in a cell make it easier for certain molecules to diffuse across a membrane?
If there's a transfer protein then its NOT diffusion ... its active transport.
