What else can I help you with?
What is a membrane protein and how does it function within the cell membrane?
A membrane protein is a type of protein that is embedded within the cell membrane. It functions by helping to transport molecules in and out of the cell, acting as receptors for signaling molecules, and providing structural support to 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.
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.
Where in the cell are protein pumps located and what is their function?
Protein pumps are located in the cell membrane and their function is to transport molecules across the cell membrane, regulating the movement of substances in and out of the cell.
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.
Were in the cell are protein molecules formed?
Proteins are formed in the ribosomes.
Where are new protein molecules made?
New protein molecules are made in the cytoplasm of the cell.
What receives protein and newly formed materials and distribute them to other parts of the cell?
The Golgi apparatus receives proteins and other newly formed materials and distributes them to other parts of the cell. It gathers simple molecules and combines them to make molecules that are more complex. It then packages them in vesicles for transport.

What is the role of protein channelsin the cell membrane?
Protein channels allow the cell membrane to transfer large molecules across it. Remember, diffusion only occurs with small molecules. Protein channels are a necessity to transfer larger molecules.
Where are proteins molecules made?
New protein molecules are made in the cytoplasm of the cell.

State one function of the protein molecules that are located in cell membranes?
One function of protein molecules in cell membranes is to transport molecules in and out of the cell. These proteins act as channels or carriers that help regulate the movement of substances across the membrane.
What are the molecules that give the cell membrane a mosaic structure?
protein molecules in the cell membrane gives the mosaic structure .
What is the cell made of?
The cell membrane is made of carbohydrate, lipid, and protein molecules.
What is formed by phospholipid molecules?
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.
