Analyzing the Question

To determine what percentage of taste perception is affected by smell, we can look at common scientific conclusions regarding the senses.

1. Understanding Taste and Smell:

   • Taste primarily involves the activation of taste buds on our tongue, which recognize basic tastes like sweet, salty, sour, bitter, and umami.
   • Smell, on the other hand, plays a crucial role in flavor perception by enhancing and complementing what we taste.

2. Research Findings:

   • Research has indicated that the sense of smell significantly contributes to what we perceive as flavor, with estimates suggesting that a large portion of our taste experiences are influenced by olfactory input.

Relevant Concepts

• Majority of flavor perception comes from both taste and smell and not just from the flavor receptors on the tongue.

Analysis of Choices

• 80–90%: This range aligns with various studies that suggest olfactory senses are responsible for a significant percentage of flavor perception.
• 100%: This option is incorrect as taste and smell both contribute to flavor.
• 40–50%: This seems too low based on current scientific consensus.
• 10–20% and 0%: These are also unlikely to align with established understanding of taste and smell relation.

Conclusion

Based on scientific studies around taste perception and olfactory influence, the most accurate answer is:

Final Answer

80–90% of what we perceive as taste is due to smell.
