Document Summary

Bio 35 - lecture 11 - interlude on what chemical transmission is not: action potential. Tryptophan is a precursor for serotonin: true, false. Turkey has tryptophan (0. 35g for 115g of turkey meat but not enough to induce. Know 3 monoamines: serotonin, dopamine, norepinephrine, epinephrine. They have both something going inside, but. Mao breaks down extra monoamines, so if you"re blocking it it increases the number of monoamines. Things are just broken up or put together (recycled) It hits transporters in the presynaptic side. How is current carried in a neuron: electrons, charged ions, uncharged ions, proteins, dna. In action potential, opening and closing of v-gated k+ and na+ channels are well timed. Depolarize membrane potential away from the resting potential toward equilibrium potential for na+ (e_na) Step 3: after a delay, na+ channels inactivate helping k+ channels to hyperpolarize membrane potential.
