A given photon of light may trigger an action potential with thousands of times more energy. Which of the following is often involved in the amplification of the signal strength in a sensory cell?
A) the receptor
B) ion channels
C) enzyme-catalyzed reactions
D) glutamate

Question

Quizplus · Accepted Answer

Enzyme-catalyzed reactions are often involved in the amplification of signal strength in sensory cells. They can trigger a cascade of reactions that amplify the initial signal, leading to a much larger response, such as the triggering of an action potential with significantly more energy than the initial stimulus.
