Final answer:
Deficiency in adrenocorticotropic hormone (ACTH) can result in a life-threatening condition as it leads to lower cortisol production, essential for regulating the body's stress response and homeostasis.
Step-by-step explanation:
The student has asked which hormone deficiency may lead to a life-threatening condition. Among the options provided - prolactin, oxytocin, follicle-stimulating hormone (FSH), and adrenocorticotropic hormone (ACTH) - the correct answer is d. Adrenocorticotropic hormone (ACTH).
A deficiency in ACTH can lead to a potentially life-threatening condition because this hormone stimulates the adrenal cortex to release cortisol, a critical hormone in regulating metabolism, immune response, and stress response. Without sufficient levels of cortisol, the body may not respond appropriately to stress, leading to a condition known as adrenal insufficiency or Addison's disease.
While hormones like prolactin and FSH are important for reproductive functions, they are generally not associated with life-threatening conditions when deficient. Oxytocin plays a role in childbirth and lactation and also is not typically associated with life-threatening conditions due to its deficiency.
However, ACTH deficiency directly impacts the functioning of the adrenal glands, which play a crucial role in maintaining homeostasis in the body. The correct option is d.Adrenocorticotropic hormone (ACTH)
