Question


All of the following statements about hormones are correct except: They are produced by endocrine glands They travel to different areas of the body They are carried by the circulatory system They are used to communicate between different organisms They elicit specific biological responses from target cells Which of the following is primarily responsible for promoting lactation? Vasopressin oxytocin prolactin cortisol prolactin inhibitory factor both (c) and (e) above Thyroxine is stored in the thyroid in peptide linkage in thyroglobulin is transported in the blood mostly bound to protein is a derivative of tyrosine a and b above a, b and c above

Explanation / Answer

6.Hormones — produced by the endocrine system — are also transported through the blood in our circulatory system.
They are not used to communicate between different organisms.

So answer is communicate between different organisms., D

7. Hormone called Prolactin secreted by the pituitary gland in the brain is responsible for the alveoli making milk. Prolactin rises when the baby suckles.
PIF), dopamine, a substance that inhibits secretion of prolactin by the anterior pituitary gland.

So answer is prolactin, C


8. T3 and T4 are stored in peptide linkage within thyroglobulin in follicular lumen
Thyroid hormones exhibit low solubility in aqueous solution so when they enter the blood they bounded to career protein
The thyroid hormones, triiodothyronine (T3) and its prohormone, thyroxine (T4), are tyrosine-based hormones produced by the thyroid gland that are primarily responsible for regulation of metabolism.

So answer is E
