Antidiuretic hormone promotes the retention of water by stimulating

The activation of the adenylate cyclase and therefore aquaporines

Explanation:

The anti diuretic hormone, also known as vasopressin, is produced in the hypothalamus where it’s released into the bloodstream throughly the axons and to the pituitary gland.

The main function of this hormone is to control blood pressure acting on kidneys and blood vessels, reducing the volume of water in urine by letting it go back into the body.

The anti diuretic hormone binds to the V receptor coupled to G in the principle cells located in the late distal tubule and collecting ducts. This ligation leads to the activation of the adenylate cyclase and finally the activation of aquaporines yo absorbe water into the cell.
