- Enzymes order like a floors order in a building: 11b, 21, 17a
- Deficiency increase the upper floor enzyme:
- 11b deficiency increases 21, and 17a
- 21 deficiency increases 17a
- ALL deficiencies have:
- Increased ACTH
- Decreased Cortisol
- When Aldosterone is increased -> Na increased vs K decreased (opposite)
- If Na increases = Blood pressure increases = fluid retention
- K is H brother and pH enemy -> K increases = pH decreases
