<prompt> Answer this question truthfullyHow does angiotensin II stimulate aldosterone synthesis and which enzyme is involved in this process?  <response>: <reason> Angiotensin II stimulates aldosterone synthesis by acting on the zona glomerulosa of the adrenal gland and increasing the activity of the enzyme aldosterone synthase. Aldosterone is a hormone that regulates the balance of sodium and potassium in the body and is important for maintaining blood pressure and fluid balance. Angiotensin II is a potent vasoconstrictor that is involved in the regulation of blood pressure and fluid balance. When blood pressure is low, the renin-angiotensin-aldosterone system is activated, leading to the production of angiotensin II and subsequent stimulation of aldosterone synthesis.
