The following is a list of Powerpoint presentations for Bio308 Cell Biology. Remember the slides cannot replace 'being there' because they do not contain the nuances of discussion that occurred in the room (and they don't respond to questions well)

Review and Graves' Disease Case Study lectures

Introduction to class, Remember to look over Grinnell article

Review: Biological Membranes

Review: Biological membranes continued: Fluid Mosaic Model, Lipid Rafts, Organelles and functions
Graves' Disease Case Study Introduction

Introduction to extracellular signaling: Types of signals and types of receptors and which occur in Thyroid Stimulation

So many signals. How does a cell know when to respond. Protein structure and testing hypothesis 1
molecular models: alpha helix , beta sheet
these models and others appearing here are from Essential Cell Biology Interactive 2: companion book by same authors. Provided since the CHIME versions in CBI (provided w/ our text) are becoming less accessible with current programs. Used with verbal permission of publishers. Restricted access-- Must use Davidson username and password

Conformational changes allowing communication
molecular model: ras and DNA helicase , two examples of allosteric modulation resulting in large conformational changes

Signaling within cells, second messengers and more

Activation by another means: role of immune system in Graves' disease

Protein expression: the players and translation

It's made- how does it end up in the correct place?

It's made- how does it end up in the correct place? Signal sequences and patches & ER translocation

Weaving through the membrane and Getting to the correct cellular location: Vesicular traffic and the SNARE hypothesis
