Zwickey on Medical Paradigms

Part of my method for keeping my boat afloat in this world is keeping a calendar, and I am currently going through September to make sure nothing fell through the cracks. Sometimes, when lacking other paper, I take notes in my calendar. On September 6 I took some notes during Orientation at NCNM on Zwickey's talk. Here's what I thought worth noting.

Links List Updated

In case you care, the first few sites are what I am using. Aside from this and gmail/maps. I am consistently impressed with Wikipedia and would like to join the team that helps maintain it. Only a few times have I run across inaccuracies, and I would like to know where to report them. I can't help it, I have an editorial bone. I'm going to send a short piece on core fitness to the school paper. Today. Get into the school paper. I've always wanted to do something with the paper. I think I'm going to let the research option go. Even though I am impressed with Zwickey. Randomness. I'm going for a WALK.

Organ Systems I: Metabotropic Transmission (4a & b) and Enzymes

Test yourself, multiple guess style:

Metabotropic transmission involves:
I. Lipophilic transmitters binding to receptors on the extracellular side of a cell membrane
II. Lipophobic transmitters binding to receptors on the extracellular side of a cell membrane
III. Lipophilic transmitters binding to receptors on the intracellular side of a cell membrane
IV. Lipophobic transmitters binding to receptors on the intracellular side of a cell membrane.

A. I.
B. II.
C. II & III.
D. III & IV
E. All of the above

Enzyme subtypes
Match the enzyme type with the description:

1. PROTEASE
2. OXYGENASE
3. ISOMERASE
4. PHOSPHATASE
5. DEHYDROGENASE
6. KINASE
7. SYNTHETASE
8. SYNTHASE
9. TRANSFERASE

A. uses ATP to form a bond between substrates
B. removes the phosphate from the substrate
C. binds two substrates without using ATP
D. incorporates oxygen into substrate, mono- or di- oxygenase
E. cleaves peptide bonds by addition of water
F. interconverts isomers
G. moves group between substrates
H. transfer hydrogen from substrate to coenzyme
I. transfer phosphate from ATP to another molecule

Organ Systems I: Transmitters (Part 5)

I believe we're talking about NEUROtransmitters, here, but Brons is abstruse. Small molecule transmitters are fast acting in acute sensory and motor responses of nervous system. Both direct and indirect. Removed from synapse by diffusion, enzymes or reuptake. Drugs often work by affecting synthesis or removal of transmitters. The action of a neurotransmitter is determined by its receptors. One neurotransmitter may affect different types of receptors each with a different action.
