Hint: Proteins are necessary nutrients for human health. They are a component of bodily tissue and may also be used as a fuel source. Proteins are polymer chains that are made up of amino acids that are connected by peptide bonds. Proteins are broken down into smaller polypeptide chains in the stomach during human digestion by hydrochloric acid and protease enzymes.
Complete answer:
Peptide hormones and protein hormones are hormones with peptide or protein molecules in their molecules. The latter's amino acid chains are longer than the former's. The endocrine system of animals, including humans, is affected by these hormones. The majority of hormones are either amino acid–based (amine, peptide, or protein) or steroid hormones. The former are water-soluble and operate on target cells' surfaces through second messengers; the latter are lipid-soluble and pass through target cells' plasma membranes (cytoplasmic and nuclear) to act within their nuclei.
Hormonal proteins are messenger proteins that aid in the coordination of many physiological functions. Insulin, oxytocin, and somatotropin are a few examples. Females' contractions are stimulated by oxytocin during delivery. Oxytocin is a neuropeptide and peptide hormone that is generated in the brain and released by the posterior pituitary gland. It helps in social bonding, reproduction, delivery, and the postpartum period. Oxytocin is a hormone that is released into the circulation in reaction to sexual activity and during childbirth. It's also accessible as a prescription medication. Oxytocin induces uterine contractions in either form, speeding up the birthing process.
Thus the correct answer is option ‘B’.
Note: A positive feedback system regulates oxytocin production and secretion, in which its initial release encourages the creation and release of more oxytocin. When oxytocin is produced during a uterine contraction during the beginning of delivery, for example, it promotes the creation and release of additional oxytocin, as well as an increase in the strength and frequency of contractions.
