The following question regards action potentials andneurons:
1.) A.) How is the physiology different for an excitatorysynapse vs. an inhibitory synapse? Consider neurotransmitterdifferences, ion channel differences, and how they affect thepotential of the post synaptic cell
B.) (3 points) How is an electrical gradient produced across agradient? How is this related to having a membrane potential?
C.) (4 points) A) Describe negative feedback in physiology. B)How is negative feedback important for maintaining homeostasis?
D.) (4 points) Under what circumstances would cells producelactate? If a cell produces and canâ€™t use lactate, what happens toit?
