What is the Unit membrane model of the plasma membrane?

Answer 1

Here's answer with explanation.

#color(red)(Introducer)=# Sc. Robertson

According to him, the cell membrane is made of a three layer sequence of protein-lipid-protein.

The external layer is a hydrophilic layer made of protein molecules of diameter #20A-25A#. The middle layer is a light hydrophobic layer made of phospholipids of diameter #25A-35A#.

The total breadth of the cell membrane is #65A-85A#.

Answer 2

Connor Abernathy

According to the Unit Membrane Model, the lipid bilayer is the fundamental structural unit of the plasma membrane, with proteins scattered within or attached to the bilayer. The model suggests that the plasma membrane is composed of a trilaminar structure with two electron-dense layers sandwiching a less dense layer.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
