What type of ion channels are these? O Voltage-gated channels O Leak channels O Mechanically-gated channels • Chemically-gated channels QUESTION 37 A neuron receives a neurotransmitter from neuron A and within a few milliseconds, receives another from neuron B. Each signal causes a potential that would by itself be insufficient to trigger an action potential, but the combined effect of the two graded potentials is sufficient ta action potential.
