How the Kidneys Regulate Acid Base Balance Protons and Buffers. Whereas the buffers in your body and your lungs are involved in the rapid adjustment of your blood's pH, the kidneys adjust the pH more slowly. Under normal conditions, the kidney's main role in acid-base balance is through the excretion of acid in the form of hydrogen (H +) ions.The kidneys secrete excess hydrogen ions primarily in the proximal tubule.nder normal conditions, the kidney's main role in acid-base balance is through the excretion of acid in the form of hydrogen (H +) ions.

What is Carbonic Anhydrase? Bicarbonate is CO 2 - with an OH group attached. When the bicarbonate reaches the lungs, it is transformed back to carbon dioxide, so it can be exhaled from the body. Carbonic anhydrase converts carbon dioxide to bicarbonate in a reversible reaction, primarily in red blood cells.

- Carbonic anhydrase inhibitors. A drug may be classified by the chemical type of the active ingredient or by the way it is used to treat a particular condition. Each drug can be classified into one or more drug classes. Carbonic anhydrase inhibitors cause increased excretion of bicarbonate with accompanying sodium, potassium and water, resulting in an increased flow of alkaline urine. They inhibit transport of bicarbonate into the interstitium from the proximal convoluted tubule.

- Vitamin C. Vitamin C, or ascorbic acid, also contributes to kidney function. As an antioxidant vitamin, vitamin C protects your cells from oxidative stress -- cellular damage that increases your risk of diseases, including kidney disease.alcium and Potassium. The minerals calcium and potassium also contribute to kidney function. The podocyte cells in your kidneys rely on both calcium and potassium to help control blood filtration, according to a study published in the Journal of the American Society of Nephrology in 2004.

Carbonic anhydrase From Wikipedia, the free encyclopedia. The carbonic anhydrases (or carbonate dehydratases) form a family of enzymes that catalyze the rapid interconversion of carbon dioxide and water to bicarbonate and protons (or vice versa), a reversible reaction that occurs relatively slowly in the absence of a catalyst.he active site of most carbonic anhydrases contains a zinc ion; they are therefore classified as metalloenzymes. One of the functions of the enzyme in animals is to interconvert carbon dioxide and bicarbonate to maintain acid-base balance in blood and other tissues, and to help transport carbon dioxide out of tissues.

Electrolytes Bicarbonate (HCO3). This electrolyte is an important component of the equation that keeps the acid-base status of the body in balance. Water + Carbon Dioxide = Bicarbonate + Hydrogen. The lungs regulate the amount of carbon dioxide, and the kidneys regulate bicarbonate (HCO3).This electrolyte helps buffer the acids that build up in the body as normal byproducts of metabolism. For example, when muscles are working, they produce lactic acid as a byproduct of energy formation.icarbonate (HCO3).

Excretory system When cells break down carbohydrates (compounds consisting of carbon, hydrogen, and oxygen and used as a food), they produce water and carbon dioxide as waste products. If these useless waste products are allowed to accumulate in the body, they would become dangerous to the body's health. The kidneys, considered the main excretory organs in humans, eliminate water, urea, and other waste products from the body in the form of urine.
