∙ 11y agoThere are actually six:
1.Transport
2.Enzyme activity( the active site is exposed)
3.Signal Transduction (chemical messenger)
4.Cell-Cell recognition
5.intercellular joining
6.help maintain shape, attachment to cytoskeleton

What are the types of proteins synthesize in the free ribosome?
Protein synthesis on ribosomes attached to ER membrane: secreted proteins integral membrane proteins soluble proteins destined for life in a membrane bound compartment
Functions of proteins embedded in the membrane?
There are two types of proteins that are embedded in phospholipid membranes, extrinsic and intrinsic. Extrinsic proteins are only partially embedded in the membrane. They aid the structural stability of the membrane and when in conjunction with glycolipids can be involved in cell recognition. Intrinsic proteins pass all the way through a membrane. Some of them may be channel proteins which act as passages through the membrane for some molecules and ions.
How can a lipid bilayer be fluid yet asymetrical?
There are proteins embedded in the membrane also. Some of these proteins exist on the aqueous side (outside) while others are only embedded on the inside. These are called peripheral membrane proteins. Some proteins go span the entire length of the lipid bilayer and are called transmembrane proteins. Peripheral membrane proteins are only temporarily attached and can become free by some types of stresses (i.e. detergents, solvents etc.). Integral membrane proteins are proteins that are permanently attached to the membrane.
What type of proteins are used in facilitated diffusion?
they can be of varying types. examples include like porins, aquaporins and ion channles.
What proteins are on the surface of the cell membrane?
The cell membrane contains many integral membrane proteins (proteins permanently attached to the surface), over the entire of its surface. These may include integrins, cadherins, desmosomes, clathrin-coated pits, caveolaes, and different structures involved in cell adhesion (the binding of a cell to the membrane surface).
What are the two proteins found in the cell membrane?
The two main proteins found in the cell membrane are integral proteins and peripheral proteins. Integral proteins are embedded within the membrane and can span across it, while peripheral proteins are located on the surface of the membrane and are not embedded within it. Both types of proteins play important roles in various cellular functions including transport, communication, and cell signaling.
What are the types of proteins synthesize in the free ribosome?
Protein synthesis on ribosomes attached to ER membrane: secreted proteins integral membrane proteins soluble proteins destined for life in a membrane bound compartment
What are 4 types of proteins found in cell membrane?
Receptor proteins, recognition proteins, transport proteins, and enzymatic proteins.
What are the four types of protein in a cell membrane?
transport proteins receptor proteins enzyme proteins cholesterol

What types of macromolecules compose the plasma membrane?
Lipids, Proteins and Carbohydrates
Which of the following types of membrane proteins are responsible for facilitated diffusion?
transport protiens

What are the different types and functions of proteins determined by?
They are determined by the sequence and number of amino acids.
In addition to proteins organic molecules is also found in cellular membranes?
Three different types of molecules appear in the membrane of a cell. These molecules are lipids, proteins, and carbohydrates.
What type of proteins are used in facilitated diffusion?
they can be of varying types. examples include like porins, aquaporins and ion channles.
What is found in a membrane?
phospholipid biolayer is the membrane it self. the protein is what gets stick in the membrane. protein In context of unit membrane, it consists of a fluid mosaic of phosphoplipid bilayer and proteins. A phospholipid bilayer is made up of two layers of phospholipids with their non-polar tails facing away from the aqueous environment and polar heads towards the aqueous environment. They make up 40% of the membrane. Proteins make up 60% of the membrane and are of two types: 1. Integral proteins 2. Peripheral proteins There can also be presence of cholesterol molecules in the membrane in the hydrophobic region.
