Why would stopping the release or action of chemicals at a synapse disturb nervous coordination?
Answer and explanation
Correct answer: The message would not cross the gap between two neurons
A synapse is the functional junction between two neurons. When an impulse reaches the presynaptic ending, neurotransmitter chemicals are released into the synaptic cleft and bind to receptors on the next cell. This transfers the signal across the gap. If chemical release or reception is blocked, the next neuron may not be excited, so coordination is interrupted. Thus A is correct; B, C and D are unrelated biological claims.
