On average, what is the lifespan of a gustatory receptor cell?

• A. 5 days
• B. 10 days
• C. 20 days
• D. 30 days

Answer: (B)

The lifespan of a gustatory receptor cell, commonly known as a taste receptor cell, is approximately 10 days. These cells are integral to the process of taste, as they detect chemical substances in food and send signals to the brain for interpretation. Gustatory receptor cells are continuously regenerated throughout a person’s life to maintain the function of the taste buds. The relatively short lifespan of these cells is due to the harsh environment in which they operate, which includes exposure to various chemicals, food particles, and the mechanical action of chewing. This rapid turnover is crucial for sustaining the ability to taste by ensuring that damaged or aged cells are replaced quickly. Other options, though close to this lifespan, do not accurately represent the average time it takes for the receptor cells to undergo apoptosis and be replaced by new cells. The choice of 10 days best reflects the biological reality of gustatory receptor cell turnover.
