1 Chapter 7 / Chapter 8 Membrane Structure and Function

2 Phospholipid: Chapter 7 / Chapter 8 Membrane Structure and Function

3 Phospholipid bilayer: Chapter 7 / Chapter 8 Membrane Structure and Function

4 Fluid mosaic model: Chapter 7 / Chapter 8 Membrane Structure and Function

5 Fluid mosaic model: Chapter 7 / Chapter 8 Membrane Structure and Function Protein “islands” float in the phospholipid bilayer Cholesterol reduces fluidity Unsaturated phospholipids increase fluidity.

6 Fluid mosaic model: Chapter 7 / Chapter 8 Membrane Structure and Function Integral proteins – embedded in the lipid bilayer Peripheral proteins – attached to surfaces.

7 Functions: Chapter 7 / Chapter 8 Membrane Structure and Function Transport Enzymatic activity Signal transduction Cell-cell recognition (CHO) Intercellular joining Attachment to matrix.

8 Synthesis: Chapter 7 / Chapter 8 Membrane Structure and Function Manufactured in the ER Modified in the ER and Golgi apparatus Inside ≠ outside.

9 Permeability: Chapter 7 / Chapter 8 Membrane Structure and Function Hydrophobic – goes right through Hydrophilic – needs transport proteins.
