Chemoreceptors interpret?

Chemoreceptors interpret?

• A. Mechanical stimulation
• B. Light
• C. Temperature
• D. Chemical stimuli, such as taste or smell

Answer: (D)

Chemoreceptors interpret chemical stimuli. They detect molecules dissolved in the environment or in body fluids, such as tastants and odorants, and convert those chemical signals into neural signals that we perceive as taste or smell. Chemoreceptors also monitor internal chemistry, like pH or gas levels (CO2, O2), to help regulate breathing and metabolism. This is distinct from mechanoreceptors, which respond to mechanical forces; photoreceptors, which respond to light; and thermoreceptors, which respond to temperature changes.
