Document Summary
As always you are responsible for all the materials we covered in lecture. The purpose of this study guide is to help you think about the material. Be able to describe these experiments and predict when you would use these. Patch clamp: used to determine the probability of an ion channel being found in it"s open conformation. Optical trap: used to determine the fluidity of membranes. Frap: used to measure the movements of proteins in plasma membranes. Squid axon experiment: used to determine the ion content(?) of axons. Optogenetics: technique used to selectively activate neurons. Questions: 11-4, 11-6,11-7; 11-8 (a-e,g), 11-10 (a-d), 11-11, 11-13, 11-18. Describe some of the functions of the plasma membrane. What type of macromolecules is the plasma membrane composed of. To form barriers, form compartments, cell communication, motility and movement. Which molecules are allowed to freely diffuse in and out of the membrane: This means the plasma membrane is very thin and fragile.
