Question

toyer loses its fluidity when it freezes aquaporins can no longer function after freezing. O the integrity of the lipid bilayer is broken when the membrane freezes. QUESTION 9 What are the membrane structures that function in active transport? peripheral proteins O carbohydrates cholesterol integral proteins cytoskeleton filaments QUESTION 10 Which of the following is true of integral membrane proteins? They are loosely bound to the surface of the blayer They are not mobile within the bayer They lack tertiary structure They are usually transmembrane proteins. They serve only a structural role in membranes Chi Sead to the Type here to search

Answer 1

9. Integral proteins

10. Transmembrane proteins

Plasma membrane is embedded with many types of proteins. The two most important types are the intrinsic and extrinsic proteins.

Intrinsic proteins	extrinsic proteins
Also known as embedded proteins or transmembrane proteins	also known as peripheral membrane proteins
Embedded inside the membrane and span both the surfaces of the membrane	present at the Periphery of the membrane either on the extracellular surface or towards the intracellular surface of the membrane
Involved in transportation of molecules from one surface of the membrane to the other surface	involved in cell signalling
