Question

Quizplus · Accepted Answer

Graded potentials can do all of the listed things. They can initiate an action potential, depolarize the membrane to the threshold voltage, or hyperpolarize the membrane. They can also be either excitatory postsynaptic potentials (EPSPs) or inhibitory postsynaptic potentials (IPSPs) depending on their effect on the postsynaptic neuron. Therefore, all of the statements are true.
