Question

Quizplus · Accepted Answer

A particular odor stimulates a particular group of odor receptors. This is because each odor molecule has a specific shape that matches certain chemical receptors in the nose, triggering a response. The brain then interprets the combination of activated receptors as a specific smell. While it is true that different regions of the brain are involved in processing different smells (choice C), and that there are thousands of different odor receptor cells (choice B), choice D is the only statement that accurately reflects how odor perception works at the cellular level. Choice A is also incorrect because there is no evidence to suggest that the different types of smells are processed in different areas of the nose.
