In recent years, this model has been modified. In this regard, which of the following statements is incorrect? Which of the following is not true about integral membrane proteins:
(a) they are anchored to the cell membrane by electrostatic interactions (b) they can only be disrupted from the lipid bilayer by detergents (c) some span the cell membrane once or more times (d) they are always in contact with both ecf and icf (e) they are covalently bound to the lipid bilayer components Correct option is d) the cell membrane is composed of lipids that are arranged in bilayer. It also posses carbohydrates and proteins along with lipids.
Proteins are of 2 types: Integral proteins are partially or totally buried in the membrane whereas peripheral proteins lie on the surface of. Carbohydrates are never found in plasma membrane is not true.
The biochemical investigation done on cell membrane clearly demonstrate that the cell membrane possess protein and carbohydrates as biochemical components. The other options stand true for plasma membrane. Plasma membrane is present in both plant and animal cells.

C) they are usually transmembrane proteins. D) they are not mobile within the bilayer. E) they serve only a.
Which of the following is not true about integral membrane proteins? They have hydrophobic residues arranged to face the lipid core b. They adopt specific orientations across the lipid bilayer c.
They can be separated from the membrane using high salt concentrations d. Which of the following is true of integral membrane proteins? A) they lack tertiary structure.
The first three statements are true, but the fourth is not. Proteosomes degrade cytosolic proteins and membrane proteins, but they are not found in the nucleus.
