Calcium reabsorption by the kidneys is promoted by the hormone: cortisol. calcitonin. aldosterone. parathyroid hormone. adh
Calcium reabsorption by the kidneys is promoted by the hormone parathyroid hormone.
What is parathyroid hormone?The parathyroid glands emit a peptide hormone known as parathyroid hormone, sometimes known as parathormone or parathyrin, which regulates the serum calcium content through acting on the gut, kidney, and bone.One or more of the parathyroid glands are hyperactive in primary hyperparathyroidism. The gland thus produces an excess of parathyroid hormone (PTH). Too much PTH raises calcium levels in the blood, which can result in health issues like kidney stones and bone weakening.The following processes are stimulated by the parathyroid hormone: bones' release of calcium into the blood. The intestines' absorption of calcium from meals. kidneys' preservation of calcium.Hypoparathyroidism is a condition in which parathyroid hormone secretion or activity is low. This lack of PTH causes blood phosphorus and calcium levels to rise and fall, respectively.

The body's cells and tissues all have this protein, which connects to and binds to DNA there. The majority of genes' activity is controlled by transcription factor IID.A preinitiation complex made up of a number of initiation components must be assembled before RNA polymerase II can begin transcription of a gene from its core promoter region. It is believed that the TFIID transcription factor complex, which is made up of the TATA-binding protein (TBP) and TBP-associated factors (TAF(II)s), binds to the various promoters in a sequence-specific manner to initiate the assembly of this complex.
