There is a separation of the charge by a membrane, resulting in its ability to do work. b. An RMP of –60 mV indicates that there are more positive ions inside the axon than an RMP of –70 mV. c. A resting membrane potential (RMP) of –90 mV indicates the there are more positive ions inside the axon than an RMP of –70 mV. d. There is a difference in the charges found on the inside of the membrane to the outside.arrow_forwardGlutamate is an excitatory neurotransmitter associated with learning and memory.
