Adenine always pairs up with either Uracil (RNA) or Thymine (DNA)
Cytosine always pairs up with Guanine (Both DNA and RNA)
When the kidney's own blood supply decreases, they release<u> renin, </u>which leads to secretions of aldosterone from the adrenal cortex.
Renin is an enzyme produced by certain kidney cells. It is a component of the renin-angiotensin-aldosterone system, which regulates blood pressure through a chain of reactions. Specifically, renin regulates the adrenal glands' synthesis of the hormone aldosterone.
- Renin transforms angiotensinogen (a liver-produced precursor to angiotensin) into angiotensin I. Angiotensin is a hormone that causes constriction of the blood vessels.
- Angiotensin I is then converted to angiotensin II. Angiotensin II constricts blood vessels and promotes aldosterone release.
- Aldosterone helps the kidneys retain water and salt, thereby boosting the body's water content. This causes the blood pressure to rise.
