Which signaling system involves the LONGEST time interval between release of a signaling molecule and activation of a receptor?
A)autocrine
B)contact-dependent
C)paracrine
D)endocrine

Question

Quizplus · Accepted Answer

Endocrine signaling involves the release of hormones into the bloodstream which can travel long distances before reaching their target cells. This can result in a longer time interval between release of the signaling molecule and activation of the receptor compared to autocrine, paracrine, and contact-dependent signaling which occur over shorter distances.
