D) by being metabolized and converted via presynaptic cells

Question

Quizplus · Accepted Answer

Hormones can be considered as similar to metabotropic neurotransmitters as they bind to specific receptors on cells and activate secondary messenger cascades to produce their effects. This is different from ionotropic neurotransmitters which activate ion channels directly. The other options are incorrect as hormones do not attach to muscle fibers nor are they metabolized and converted via presynaptic cells.
