If the clearance of neurotransmitter from the synaptic cleft is prevented, which of the following will be the most likely result?
A) The presynaptic cell will be unable to release more neurotransmitter.
B) The postsynaptic cell will return to its resting potential.
C) The postsynaptic cell will respond more quickly to a change in output of the presynaptic cell.
D) The buildup of neurotransmitter will cause activation of the presynaptic cell.
E) The postsynaptic cell will be constantly activated.

If the clearance of neurotransmitter from the synaptic cleft is prevented, the postsynaptic cell will be constantly activated by the buildup of neurotransmitter. The excess neurotransmitter will continue to bind to the receptors on the postsynaptic cell, causing continuous activation and potentially leading to overexcitation and cell damage. This can lead to disorders such as epilepsy or neurodegeneration. The other options (A, B, C, and D) do not accurately reflect the consequences of inhibited clearance of neurotransmitter.
