Question

Which of the following does not involve metabotropic transduction?

A. Tasting sweet or bitter.
B. Smelling flowers.
C. Tasting salt.
D. Seeing flowers.

Answer 1

Seeing flowers does not involve metabotropic transduction.

Step-by-step explanation:

The taste sensations in humans involve different mechanisms for transduction. Salty and sour tastes are triggered by the ions Na+ and H+, respectively. Sweet, bitter, and umami tastes require a G-protein coupled receptor. Therefore, seeing flowers does not involve metabotropic transduction.
