Incorrect statement regarding synapses:
The incorrect statement regarding synapses is option C: Impulse transmission across a chemical synapse is always faster than that across an electrical synapse.
Explanation:
Synapses are specialized junctions that allow communication between neurons. There are two main types of synapses: electrical synapses and chemical synapses.
Electrical synapses:
- Electrical synapses are characterized by direct physical contact between the membranes of the pre- and postsynaptic neurons.
- These synapses contain gap junctions, which are specialized protein channels that allow electrical current to flow directly from one neuron to another.
- The flow of ions through gap junctions enables the rapid transmission of electrical signals.
- The membranes of the presynaptic and postsynaptic neurons are in close proximity, allowing for quick and efficient transmission of impulses.
- Electrical synapses are capable of bidirectional transmission and are found in various regions of the nervous system, including the brain and spinal cord.
Chemical synapses:
- Chemical synapses are the most common type of synapse in the nervous system.
- Unlike electrical synapses, there is a small gap called the synaptic cleft between the presynaptic and postsynaptic neurons.
- When an action potential reaches the presynaptic terminal, it triggers the release of neurotransmitters into the synaptic cleft.
- The neurotransmitters diffuse across the cleft and bind to receptors on the postsynaptic membrane, leading to the generation of a new electrical signal in the postsynaptic neuron.
- This process is slower compared to electrical synapses since it involves the release, diffusion, and binding of neurotransmitters.
- However, chemical synapses have the advantage of being able to modulate and regulate the strength of the signal through various mechanisms, such as reuptake and enzymatic degradation of neurotransmitters.
Conclusion:
The incorrect statement is option C: Impulse transmission across a chemical synapse is always faster than that across an electrical synapse. While chemical synapses have the advantage of modulation and regulation, impulse transmission across electrical synapses is generally faster due to the direct flow of electrical current between neurons.

Select the incorrect statement regarding synapses:a)Electrical current...
In reality, impulse transmission across an electrical synapse is generally faster than that across a chemical synapse. Electrical synapses allow for direct electrical communication between neurons through gap junctions. This allows the flow of electrical current from one neuron to another, resulting in rapid transmission of signals.
On the other hand, chemical synapses involve the release of neurotransmitters from the presynaptic neuron into the synaptic cleft. These neurotransmitters bind to receptors on the postsynaptic neuron, leading to the propagation of the signal. This process involves more complex steps, including neurotransmitter release, diffusion, binding, and subsequent signaling events, which introduce a slight delay compared to electrical synapses.
Therefore, statement (c) is incorrect because impulse transmission across a chemical synapse is generally slower than that across an electrical synapse.
