Question

Clearly, there is some redundancy in hormonal actions. Which of the following statements is NOT ALWAYS true?

(A) Some hormone effects are vital for maintaining homeostasis, warranting some redundancy.
(B) Having multiple hormones acting with the same end goal will help reach the end goal quicker.
(C) Having multiple hormones with the same end goal will rely upon the same mechanism.
(D) Some hormones act as Permissive Hormones, enabling other hormones to achieve their full effect.

Answer 1

The statement not always true is that multiple hormones with the same end goal will rely upon the same mechanism, as hormones can have different targets and methods of action.

Step-by-step explanation:

The statement that is NOT ALWAYS true when considering the redundancy in hormonal actions is: (C) Having multiple hormones with the same end goal will rely upon the same mechanism.

Hormones are vital for maintaining homeostasis and the body often uses redundant systems to ensure critical functions are preserved. This is why some hormone effects are vital, and some hormones may act permissively to enable others. However, while redundancy can help reach an end goal more reliably, it doesn't mean multiple hormones always use the same mechanisms. Hormones like insulin and glucagon demonstrate how they can have different mechanisms, despite targeting the same end goal of regulating blood glucose levels.
