A given photon of light may trigger an action potential with thousands of times more energy because the signal strength is magnified by
A) the receptor.
B) a G protein.
C) an enzyme-catalyzed reaction.
D) sensory adaptation.
E) triggering several receptors at once.

Question

Quizplus · Accepted Answer

An enzyme-catalyzed reaction can amplify the signal from a single photon of light into a much larger response, leading to the generation of an action potential with significantly more energy. This process involves biochemical pathways where enzymes amplify the signal at various steps, resulting in a large output signal from a small input.
