According to the fluid mosaic model of membrane structure, proteins of the membrane are mostly a. spread in a continuous layer over the inner and outer surfaces of the membrane. b. confined to the hydrophobic interior of the membrane. c. embedded in a lipid bilayer. d. randomly oriented in the membrane, with no fixed inside-outside polarity.

Hi everyone here we have a question saying proteins do not form a continuous layer. Instead they are embedded in the lipid bi layer. This model of membrane structures referred to as a unit membrane model. Be fluid mosaic model, C lock and key model. Or the sliding filament model. So let's look at the definitions for each of these. The unit membrane model states all membranes have an underlying Beiler composed of phosphor lipids beat. The fluid mosaic model, stakes out proteins are embedded in the lipid bi layer. See the lock and key model says that enzymes and substrates have complementary shape to fit each other like a lock and key. And lastly d. The sliding filament model is the process used by muscles to contract. So the fluid mosaic model is the model that states that proteins do not form a continuous layer. Instead they are embedded in the lipid bi layer. So our answer is be fluid mosaic model. Thank you for watching. Bye.
