In 1895, Ernest Overton proposed that cell membranes were made of lipids
According to the lipid bilayer theory, which Gorter and Grendel put forth in 1925, the cell membrane bilayer structure can be described using crystallographic research and observations of soap bubbles.
<h3>What is Cell membrane ?</h3>
All cells have a cell membrane, also known as a plasma membrane, which separates the interior of the cell from the external environment.
- A semipermeable lipid bilayer makes up the cell membrane. The movement of materials into and out of the cell is controlled by the cell membrane.
- Biological membranes serve three main purposes. First, they prevent harmful substances from entering the cell. Second, they have receptors and channels that let certain molecules, like ions, nutrients, wastes, and metabolic products,
- Third, they divide metabolic processes that are necessary but incompatible that take place within organelles.

Answer:
The correct answer is 3200000.
Explanation:
If there is only one amino acid in the peptide, the probable number of combinations would be 20. If there is only two amino acid in the peptide, the probable number of combinations will be 20^2. Similarly, for three amino acids in the peptide it would be 20^3 and for four it would be 20^4.
Thus, in the case of pentapeptide, that is, five amino acids in a peptide, the probable number of combinations will be 20^5, which comes out to be 3200000. Thus, the total number of different pentapeptides will be 3200000 that needs to be tested for receptor binding.
