Study Notes
Acid-Base Concepts
- Volatile Acid: Carbonic acid (H₂CO₃) is an example, formed from carbon dioxide and water in the body.
- Defense Mechanism with Weak Acid and Salt: The bicarbonate buffer system consists of carbonic acid (weak acid) and bicarbonate (salt).
- Abundant Inorganic Acid: Sulfuric acid (H₂SO₄) is highlighted as the most abundant inorganic acid in biological systems.
- Excretion Mechanism: The renal system plays a key role in excreting excess acids or bases, maintaining overall acid-base balance.
Functions of Carbonic Anhydrase
- Carbonic Anhydrase Role: Catalyzes the conversion of carbon dioxide and water into carbonic acid, facilitating gas exchange and pH regulation.
- Main Function: Enhances the efficiency of carbon dioxide transport and regulates bicarbonate levels in the blood.
Additional Acid-Base Mechanisms
- Fixed, Nonvolatile Acid Example: Phosphoric acid (H₃PO₄) serves as an example of a fixed, nonvolatile acid produced from metabolism.
- Rapid Defense Mechanism: The bicarbonate buffer system acts quickly to maintain pH levels, essential for physiological stability.
Bicarbonate Buffer System Components
- Bicarbonate Buffer System Components: Composed of carbonic acid (H₂CO₃) and bicarbonate (HCO₃⁻), which work together to stabilize pH in the body.
- Acid-Base Equilibrium Mechanism: Both the respiratory and renal systems collaborate to maintain acid-base equilibrium through excretion and reabsorption processes.
