Which of the following is an incorrect description of components of the biological membrane?a.Hydrocarbon tail without carbon-carbon double bonds is saturated with respect to hydrogen.b.The movement of proteins in a bilayer can be monitored using FRAPС.Most of the lipids and some of the proteins cannot move sideways in the plane of the membraneand mostly a lipid may 'flip-flop' across the membrane from one phospholipid layer to the otherO d.Cholesterol is a steroid which is wedged between phospholipid molecules of the plasmamembranes of animal cellse.A kink in one of the hydrocarbon tails results from the presence of carbon-carbon double bondsand causes increased fluidity of the membrane

Membrane composition and arrangement can be defined by a fluid mosaic model which suggest that…
