Action potentials at a chemical synapse
A) travel from presynaptic terminal to presynaptic membrane.
B) travel from postsynaptic membrane to presynaptic terminal.
C) travel back and forth from presynaptic terminal to postsynaptic membrane.
D) travel from presynaptic terminal to postsynaptic membrane.
E) stop at the presynaptic terminal and are blocked on the postsynaptic membrane.
Action Potentials
Short-lived changes in the electrical potential of a cell's membrane, leading to the transmission of nerve impulses.
Chemical Synapse
A chemical synapse is a type of synapse that utilizes chemical messengers, known as neurotransmitters, to transmit signals between neurons across a synaptic gap.
Presynaptic Terminal
The end point of a neuron where neurotransmitters are stored before being released into the synaptic cleft.

Final Answer :
D
Explanation :
Action potentials travel from the presynaptic terminal to the postsynaptic membrane, where they trigger a response in the postsynaptic cell. This directional flow is essential for the transmission of signals across synapses in the nervous system.
