Which of the following are characteristics of biological membranes? (i) Membranes are fluid structures. (ii) The sugar residues of membrane are always located on the external surface of plasma membranes. (iii) The outer and inner surfaces of all known biological membranes have different components and different enzymatic activities, i.e., membranes are asymmetric. (iv) Membrane fluidity is controlled by fatty acid composition and protein distribution. (v) Membrane proteins and phospholipids can readily rotate within the membrane, from the inside to the...
