Question

Quizplus · Accepted Answer

Catecholamines, such as adrenaline and noradrenaline, are synthesized and actively transported into preformed vesicles for storage.

Answer: D
 Thyroid hormone is synthesized and actively transported into preformed vesicles for storage within the thyroid gland.

Choice A is not the best answer as steroids are not actively transported into vesicles for storage, but rather diffuse passively across cell membranes. Choice C is also not the best answer as peptides are synthesized in the rough endoplasmic reticulum and packaged into secretory vesicles for release, rather than being actively transported into preformed vesicles for storage.
