Alexis is out mowing the lawn and starts to feel dehydrated. Her ______ will secrete vasopressin. A patient suffering from sever
adoni [48]

1. The right answer is - Hypothalamus (manufactured by the hypothalamus, stored in the pituitary gland).

Vasopressin, or antidiuretic hormone, is a peptide hormone synthesized by the supraoptic and paraventricular nuclei of the hypothalamus, and released by the posterior pituitary gland (neurohypophysis).

It mainly has an anti-diuretic role in the kidney, where it causes a reabsorption of water via an action on the distal segment of the nephron during a dehydration body. Its gene is AVP located on human chromosome 20.


2. The right answer is - Increased Secretion of Vasopressin To Maintain Less Loss Of Water.

Vasopressin has an antidiuretic action: it decreases the volume of urine by increasing the water permeability of the collecting tube. It binds to the V2 receptor, which is coupled to a Gα protein, which activates a signaling cascade through the PKA. This causes the synthesis of aquaporin 2 (transmembrane pore) as well as its translocation to the apical / urinary membrane.

What happens to an animal cell in a hypertonic solution?
jarptica [38.1K]

<span>The answer is that cell will shrink.</span>

<span>If you put an animal cell in a hypertonic solution means that concentration of the solutes is greater outside the cell, in the solution, than in the cell. Consequently,</span> the water concentration of the cell's cytoplasm is higher than that of the hypertonic solution. Since the aim is to balance water concentration on the inside and outside of the cell, the water will exit the cell. The cell will lose water and, consequently, will shrink in size.
