Which flavor is detected by taste buds at the tip of the tongue?

• A. Salty
• B. Sweet
• C. Sour
• D. Bitter

Answer: (B)

Sweet is detected by taste buds at the tip of the tongue because the receptors that respond to sugars are concentrated there, so contacting sweet molecules with the tip activates those receptors most strongly. When these receptors are triggered, the signal travels from the taste cells through the facial nerve to the brain, where a sweet sensation is interpreted. This setup helps us notice energy-rich foods early. The other flavors are associated with different regions: salty and sour signals are detected more on the sides, while bitter tends to be detected toward the back as a warning. So, the tip’s strongest association is with sweet.
