The action potential will propagate toward the cell body c. The action potential will propagate toward both the cell body and the axon terminal d. The action potential will not propagate at all e. The neuron will hyperpolarize 38. Which of the following does not play a significant role in the signal transduction pathway for glucose metabolism stimulated by the hormone epinephrine.
Individual neurons sum excitatory and inhibitory postsynaptic potentials.
Explain how the same chemical signal, such as a particular hormone, can have one effect on cell type A, a different effect on cell type B, and no effect on cell type C. 41. Male cockroaches with mutations in a receptor tyrosine kinase gene, A, are oblivious to the charms of their female comrades. This particular receptor tyrosine kinase binds to a small molecule secreted by sexually mature females. Most males carrying mutations in the gene for Ras protein are also unable to respond to females. A gene for additional mutations that partially restore the ability of males to respond to females.
