Unit 7: Cell Membrane Structure 

                Syllabus Statements

EI
The structure of biological membranes makes them fluid and dynamic. 

1.3.U1 
Phospholipids form bilayers in water due to the amphipathic properties of phospholipid molecules

1.3.S1 
Drawing of the fluid mosaic model

1.3.U2 
Membrane proteins are diverse in terms of structure, position in the membranes and function (include glycoproteins)

1.3.U3 
Cholesterol is a component of animal cell membranes

1.3.A1 
Cholesterol in mammalian membranes reduces membrane fluidity and permeability to some solutes

1.3.S2 
Analysis of evidence from electron microscopy that led to the proposal of the Davidson-Danielli model

1.3.NOS1 
Using models as representations of the real world-there are alternative models of membrane structures (NOS 1.11)

1.3.NOS2 
Falsification of theories with one theory being superseded by another-evidence falsified the Davison-Danielli model

1.3.S3
Analysis of the falsification of the Davson-Danielli model that led to the Singer-Nicolson model.
