Question

Instead of cholesterol what is present in cell membrane of bacteria

Answer 1

Answer:

Hopanoids as functional analogues of cholesterol in bacterial membranes. ... The functionality of cellular membranes relies on the molecular order imparted by lipids. In eukaryotes, sterols such as cholesterol modulate membrane order, yet they are not typically found in prokaryotes

Answer 2

Answer:

Instead of cholesterol phospholipids and proteins are present in cell membrane of bacteria.

Explanation:

• A phospholipid bilayer serves as the cell membrane, entirely enclosing the bacterial cell. The key term here is "totally," as any crack in the bilayer will cause the bacteria to perish.
• In truth, several of our favourite antibacterial cleaning products actually kill bacterial cells by rupturing or rupturing the cell membrane, allowing the bacterial cell's contents to leak out and eradicating the bacteria inside.

• Both hydrophilic (water-loving) and hydrophobic (water-fearing) elements make up the phospholipid bilayer structure. On the membrane's internal and external surfaces, which are in touch with the environment and the internal contents of the cell, respectively, the hydrophilic components are arranged in a straight line.

• In order to stabilise and contribute to the structure, the hydrophobic components of the membrane face the interior of the bilayer. The cell membrane has the consistency of olive oil, despite the fact that in pictures and drawings it appears to be a firm structure.
• As a result, the membrane is stable but flows like a fluid. If you want an example, just take a look at a salad dressing bottle. The hydrophobic oil separates from the water, but when you tip the bottle, you can see that the oil layer is fluid and travels around freely.
