Question

Which of the following is not involved in transmission of a nerve impulse across a chemical synapse?

• A. Synapsin
• B. Acetylcholinesterase
• C. Calmodulin
• D. Calcium ions

Answer 1

The correct option is B Acetylcholinesterase

When the nerve impulse reaches the end of the axon, there are some chemicals released from the neurotransmitters. They diffuse across the synaptic gap, which is the small space present between the axon and the receptors. Nerve impulses can be transmitted either by the electrical by the electric synapse or the chemical synapse.

So, the correct option is 'Acetylcholinesterase'.
