How Does Information Transfer Occur at Chemical Synapses

question 36

Multiple Choice

How does information transfer occur at chemical synapses?

• A) Electrical depolarization of the nerve terminal leads to current flow directly from the presynaptic cell to the postsynaptic cell through connexons (or gap junctions).
• B) Electrical depolarization of the nerve terminal causes presynaptic calcium channels to open, leading to the direct excitation of the postsynaptic cell.
• C) Electrical depolarization of the nerve terminal causes the release of chemicals that open postsynaptic ligand-gated ion channels which pass current, depolarizing the postsynaptic cell.
• D) Electrical depolarization of the nerve terminal directly opens postsynaptic ligand-gated ion channels, which pass current, depolarizing the postsynaptic cell.
• E) Electrical depolarization of the nerve terminal leads to current flow directly from the presynaptic cell to the postsynaptic cell through voltage-gated ion channels.
