Members do not see this ad.

. The level of non-protien nitrogen in the blood is due principally to the level of -
asw: urea
my doubt is ? not Ammonia???😕 as it is d end product of protien metabolism......

2. which of the following hormone is a polypeptide
1. epinephrine 2. progesterone 3. FSH
4. testosterone 5. tri iodotyronine

thankful 2 u

2) ans is epinephrine which is a polypeptide made from tyrosine(AA)

Thankful 2 U

Water Soluble(polypeptide) Hormones Are Insulin/glucagon/fsh) Lipid Solublr Hormones Are Estadiol/prosegtrone/testosterone.)
Hence Te Answer Is Fsh.

1) ans is urea not ammonia, cause urea is water soluble and also neither acidic nor basic. while ammonia is acidic. So if it is high ph decreases to toxic level and hence ammonia is first converted to urea using energy nd then thrown out as waste.

i think its epinephrine cause it is a pure polypeptide and FSH is a glycoprotein So it has glucose and protein.

Pls correct me if i m wrong

Several important peptide hormones are secreted from the pituitary gland. The anterior pituitary secretes luteinizing hormone and follicle-stimulating hormone, which act on the gonads, prolactin, which acts on the mammary gland, adrenocorticotrophic hormone (ACTH), which acts on the adrenal cortex to regulate the secretion of glucocorticoids, and growth hormone, which acts on bone, muscle, and the liver. The posterior pituitary gland secretes antidiuretic hormone, also called vasopressin, and oxytocin. Peptide hormones are produced by many different organs and tissues, however, including the heart (atrial-natriuretic peptide (ANP) or atrial natriuretic factor (ANF)) and pancreas (insulin and somatostatin), the gastrointestinal tract (cholecystokinin, gastrin), and adipose tissue stores (leptin).[4][5]

Some neurotransmitters are secreted and released in a similar fashion to peptide hormones, and some 'neuropeptides' may be used as neurotransmitters in the nervous system in addition to acting as hormones when released into the blood. When a peptide hormone binds to receptors on the surface of the cell, a second messenger appears in the cytoplasm, which triggers intracellular responses.

Epinephrine (also referred to as adrenaline; see Terminology) is a hormone and neurotransmitter. It is a catecholamine, a sympathomimetic monoamine derived from the amino acids phenylalanine and tyrosine.

sorry i have to correct u.
epi/ne is not a polypeptide bu a a'a derivative of tyrosine.fsh is a glycoprotein and insulin is polypeptide.

HI .thanx guys. i think u ll r right. FSH is right ans 🙂
