Document Summary
Vesicle docks to pre-synaptic membrane: snares: aid in docking/ fusion of synaptic vesicles, 5. Incorrect (partially)-- many neurons synthesize and release multiple neurotransmitters at synapses: categories of receptors. Exchange of gdp to gtp on alpha subunit (also beta/ gamma: beta/ gamma activates potassium channels, 4. Ion channels: 2nd messengers, enzymes, transcription factors, enzyme-linked receptors. A molecular signal (nt: cell impermeant molecules: neurotransmitters, cell permeant molecules: steroid-based molecules, thyroxines, retinoids, cell associated molecules: cell membrane to cell membrane receptor interaction between closely apposed cells, 2. Ion channels: cascades, g-proteins and their targets: activate enzymes that regulate production of second messengers, second messengers: regulate target enzymes (pka, nuclear messengers: protein modifications induced in transcription factors modifies gene expression, cyclic nucleotide cascade, 1. Adenylyl cyclase: targeted by alpha subunit leading to increases/ decreases in. [camp]i (2nd messenger: guanylyl cyclase [cgmp]i, second messengers degraded by phosphodiesterase enzymes, 2. camp/ cgmp activate pka/ pkg (protein kinase __ , 3.
