Question

Distinguish between the following pair:

Nerve impulse and flow of electricity (transmission and speed)

Answer 1

Nerve Impulse	Flow electricity
The sodium-potassium pump transmits nerve impulses across axons by polarising and depolarising Na+ ions. Nerve impulses move at a speed of 100 m/sec.	Electricity flows through wires as electrons move between two points with different potentials. Electricity is conducted through wires at a speed of 1,50,000 km/sec.
