Answer:
Explanation:
Biological membranes have three primary functions: (1) they keep toxic substances out of the cell; (2) they contain receptors and channels that allow specific molecules, such as ions, nutrients, wastes, and metabolic products, that mediate cellular and extracellular activities to pass between organelles and between the
The main difference between the two main types of proteins associated with the plasma membrane is: the one is the integral membrane protein is permanently bound to the membrane and the peripheral membrane protein is temporarily attached to the lipid bilayer.
What are membrane proteins?
Membrane proteins are those proteins that are the reason for the structural and functional preparation of the membranes. There are various types of membrane proteins.
The main membrane proteins are:
1. integral membrane protein
2. peripheral membrane protein
The differences between integral and peripheral membrane proportions are the integral is the permanent one, they always provide support and the peripheral is there for special functions only. This is the major distinction between the two main types of proteins connected to the plasma membrane.
Thus, the integral membrane protein is permanently tied to the membrane, whereas the peripheral membrane protein is only momentarily coupled to the lipid bilayer.
