ATP-powered pumps are ATPase's that use the energy of ATP hydrolysis to move ions or small molecules across a membrane against a chemical concentration gradient or electric potential. Channel proteins transports water or specific types of ions down their concentration or electric potential gradients. Transporters move a wide variety of ions and molecules across cell membranes.
What else can I help you with?
What are the types of membrane transport across the cell membrane require a protein carrier?
The brain
What is inner membrane protein and outer membrane protein How can you get membrane protein from E. coli and how to separate the inner and outer membrane protein?
Inner membrane proteins are embedded in the inner membrane of bacteria, while outer membrane proteins are located in the outer membrane. To obtain membrane proteins from E. coli, you can disrupt the cells through methods like sonication or French press, followed by using differential centrifugation to separate the inner and outer membrane fractions based on their densities. Further purification techniques such as density gradient ultracentrifugation or membrane solubilization can be used to isolate inner and outer membrane proteins specifically.
What type of membrane protein joins cells?
Lipo-protein membrane
How are proteins positioned within the membrane?
The protein is anchored into the membrane by its nonpolar region, but the protein remains moblie. To explain it more, the middle section of the protein is made of many nonpolar amino acids. This nonpolar coil fits into the nonpolar interior of the lipid bilayer allowing the protein to float in the membrane.
How many different types of protein subunits are there?
There are four primary types of protein subunits: globular, fibrous, membrane, and disordered. Each type serves different functions within the cell and has unique structural characteristics.
What is A membrane protein with a carbohydrate chain?
A membrane protein with a carbohydrate chain is called glycoprotein
Why is that high variation of protein composition in membrane?
high variation of protein composition in membrane?
What protein that projects from the outer surface of the membrane is termed?
The protein that projects from the outer surface of the membrane is termed as an extrinsic or peripheral membrane protein. These proteins are not embedded within the lipid bilayer but instead are attached to the surface of the membrane.
What is a protein free membrane?
a membrane with no proteins -_-
How would a protein get through a cell membrane and into a cell wall?
Endocytosis: Types of Endocytosis: Phagocytosis, Pinocytosis, Receptor-Mediated
What are cell membrane pores are made of?
Cell membrane pores are made up of protein.
What is an example cell membrane?
Protein, because thats what the cell membrane does (delivers protein to the cell)
