Problem 18.134

Based on the following standard reduction potentials: Fe21(aq) 1 2e2 Fe(s) E 1 5 20.44 V Fe31(aq) 1 e2 Fe21(aq) E 2 5 0.77 V calculate the standard reduction potential for the half-reaction Fe31(aq) 1 3e2 Fe(s) E 3 5 ?

Step 1 of 3

CH:2 NEUROSCIENCE & BEHAVIOR 9/5 Neural Communication  Neuron: basic building block of the nervous system o Consists of cell body, dendrites, axons, & presynaptic/ axon terminals  Dendrites: receive information; short  Axons: transmit information; long  Myelin sheath: layer of fatty tissue that insulates some axons to speed impulses o Neural anatomy   Action potentials o Direction of neural impulse: toward axon terminals  Na= +  K= - o Action potential: brief electrical charge that travels down the axon with each one tipping the next  1. Axon is at rest: fluid on interior of axon is negatively charged while fluids on the outside are positively charged (resting potential)  2. Threshold: level of stimulation needed to trigger an action potential  3. Depolarization: neuron fires causing the first “bit” if the axon to open its gates & become depolarized  4. Neural impulse (action potential) moves down the axon causing the next section to open its gates & become depolarized  5. Sodium gates in the 1 section closes while others open allowing potassium to flow out repolarizing the axon  6. Return to rest  Neurotransmitters: o Dopamine: movement, learning, attention, & emotion
