<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>
Well, if maltose contains carbon, hydrogen, and oxygen, but not nitrogen, then maltase must contain nitrogen!
Your answer is 4.), nitrogen! :) I hope this helps!
I learned this in class and I didn’t really understand it either but I could try
Answer:
B. igneous rock
Explanation:
Igneous rock are the rocks which are formed due to the cooling of magma over the time.
There are majorly of two types
Intrusive igneous rocks : These are the rocks which are formed by the cooling of magma under the crust
Extrusive igneous rocks : These are the igneous rocks which are formed due to the cooling of magma on the crust of the Earth.
