This first-in-class lecture (Lecture 1) covers the scientific theory, the ten principles of life, and viruses (and whether or not they are living) This is the first set of introductory notes. Quality stuff! U'll need it!!

1 BIO 181 EXAM 3 STUDY GUIDE: 1. Receptors are made from membrane-bound polyribosomes. 2. Acetylcholine exocytosed from the presynaptic cell travels to the postsynaptic cell to start the action potential in the postsynaptic cell. 3. The axon from a pre-synaptic cell contacts the axon of another neuron. 4. In the motor end plate, the event that is the immediate trigger for exocytosis is: Calcium Ions 5. The receptors in post-synaptic cells are the basis on which the synapse can be ...
