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.
What is it called when molecules uses energy to move across a semipermeable membrane?
Active transport
Describe a form of active transport similar to the work of carrier proteins?
Ion channels are a form of active transport that is similar to carrier proteins. They facilitate the movement of ions across cell membranes through a protein channel that can open and close, allowing ions to pass through. This transport process is also energy-dependent and requires specific interactions between the ions and the channel proteins for movement.
What type of transport protein is a sodium potassium pump?
It is a carrier protein
Does passive transport requires the use of ATP?
Active transport requires ATP and a transport channel. The channel is made of proteins.
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.
Differences between primary and secondary active transport?
In primary active transport, the transport protein gets phosphorylated; in secondary active transport, the transport protein is not phosphorylated
What is a transport protein?
It's either a passive or active transport.
What is it called when molecules uses energy to move across a semipermeable membrane?
Active transport
How do carrier protein recognize substances to transport in active transport?
substance to pass

What does a channel protein do in the context of cellular transport?
A channel protein helps facilitate the passage of specific molecules or ions across a cell membrane, allowing for efficient and selective transport in and out of the cell.
Is aquaporin a channel protein?
Yes, aquaporin is a type of channel protein that facilitates the transport of water molecules across cell membranes.
Is facilitated diffusion type of active transport?
Facilitated diffusion is passive transport as no energy is used, and a protein channel is all that's required. After that it is simple diffusion down a concentration gradient. Anything with the word diffusion in it is passive transport. Diffusion is just the principle of passive transport.
What is the function of a channel protein in cellular transport?
A channel protein in cellular transport acts as a passageway for specific molecules to move in and out of the cell, helping to regulate the flow of substances across the cell membrane.
What is the purpose of a channel protein in cellular transport?
A channel protein in cellular transport acts as a passageway for specific molecules to move in and out of the cell, helping to regulate the flow of substances and maintain the cell's internal environment.
What type of transport protein is a sodium potassium pump?
It is a carrier protein
