<span>Because cholesterol is only minimally soluble in water (dissolves into the water at small concentrations) it needs to be transported as part of the complex with proteins-lipoproteins. Thus, lipoproteins bound by specific receptors on cell membranes. Lipoproteins, particles that transport cholesterol through the blood, contain lipid-soluble part (located inside the particle) and amphipathic or water-soluble part (one the surface of the particle). There are five types of lipoproteins: chylomicrons, very-low-density lipoprotein (VLDL), intermediate-density lipoprotein (IDL), low-density lipoprotein (LDL), and high-density lipoprotein (HDL).</span> <span>Receptors for the cholesterol (lipoprotein) are located on the surface of a plasma membrane and after the binding of lipoprotein, coated endocytic vesicles are formed from the surface. Those vesicles carry lipoprotein into the cell together with the receptor (internalization). After internalization, the receptors dissociate and recycle to the cell surface.</span>
Rabies is know to be a Lytic Virus
Answer:
In acid-fast staining, carbon fuchsin is used as a primary stain which dissolves the mycolic acid present in the cell wall of <em>Mycobacterium smegmatis </em>and penetrates through it which results in staining <em>Mycobacterium</em> red.
Staphylococcus aureus cell wall does not contain mycolic acid so carbon fuchsin does not penetrate its cell wall, therefore, it becomes colorless after destaining with acid alcohol.
After destaining step methylene blue is added to stain non-acid-fast bacteria blue. So if I mistakenly forgot to use methylene blue during the procedure <em>Mycobacterium smegmatis</em> will appear red due to carbon fuchsin present in their cell wall and S<em>taphylococcus aureus</em> will appear colorless because it is destained.
