topic 1.3: membrane structure
Essential Ideas:
- The structure of biological membranes makes them fluid and dynamic.
Membrane Structure: putting the parts together
1.3U1: Phospholipid bilayers form in water due to the amphipathic properties of phospholipid molecules.
1.3U2: Membrane proteins are diverse in terms of structure, position in the membrane, and function.
1.3U3: Cholesterol is a component of animal cell membranes.
1.3A1: Cholesterol in mammalian membranes reduces membrane fluidity and permeability to some solutes.
Exploring models: how scientists came to understand membrane structure
1.3Skill1: Drawing of the fluid mosaic model.
1.3Skill2: Analysis of evidence from electron microscopy that led to teh proposal of the Davson-Danielli model.
1.3Skill3: Analysis of the falsification of the Davson-Danielli model that led to the Singer-Nicolson model.
