Hormones that promote homeostasis
A) are not found as members of antagonistic signaling mechanisms.
B) travel to target cells without passage in the plasma.
C) utilize receptors that bind any hormone.
D) initiate signal transduction in the target cell without binding to receptors.
E) usually operate as part of a negative feedback system.

Question

Quizplus · Accepted Answer

Hormones that promote homeostasis usually operate within a negative feedback system, where increased levels of the hormone ultimately lead to a decrease in its production or release. This helps maintain a stable internal environment despite external changes. Examples of hormones that promote homeostasis include insulin, cortisol, aldosterone, and vasopressin. Choices A, B, C, and D are incorrect because hormones that promote homeostasis usually act as members of antagonistic signaling mechanisms, travel to target cells through the plasma, utilize specific receptors, and initiate signal transduction through binding to receptors.
