As part of a laboratory experiment in his psychology course, miguel is observing the activity of a recording electrode on the axon of a neuron. as an action potential
occurs what might miguel observe?
a the axon will release neurotransmitters into the synapse.
b. the avon will remain at threshold potential as negative ions continue to flood the cell.
oc the decial charge of the neuron will go from positive to negative before returning to threshold potential.
od. the curical charge of the neuron will go from negative to positive before returning to resting potential

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."

cellular respiration oxidizes food into energy in the form of atps.

glycolysis (6 c hexose) > 2x atps are used > 6c hexose biphosphate > 2 x 3c triphosphate >

2 x 3c pyruvate (2x nadh produced from nad) and (4x atp produced)

pyruvate actively pumped mitochondrial matrix.
