Relating the Bohr effect to carbonic anhydrase is simple: carbonic anhydrase speeds up the reaction of carbon dioxide reacting with water to produce hydrogen ions (protons) and bicarbonate ions. To describe equilibrium in the carbonic anhydrase reaction, Le Chatelier's principle is used. Most tissue is more acidic than lung tissue because ...
Other forms of carbonic anhydrase enzyme are not present in the plasma, restricting the equilibrium reaction of CO 2 + H 2 O = H 2 CO 3 = H+ HCO − 3. CO 2 in the plasma diffuses into the Red Blood Cell. CA is present within the Red Blood Cell, facilitating the conversion of CO 2 to HCO − 3. HCO − 3 so produced is transferred by the HCO −
Carbonic anhydrase catalyzes the conversion of carbon dioxide and water into carbonic acid. This molecule breaks down into bicarbonate and hydrogen ions. This break down process occurs in red blood cells. Ultimately, the concentration of bicarbonate ions in the bloodstream affects the formation of the protein carbaminohemoglobin in the body. [11]
The reaction catalyzed by CA1 is the same as other carbonic anhydrase family proteins: + (in tissues - high CO 2 concentration) [9]. The CA1-catalyzed reaction has a relatively low reaction affinity (Km) of 4.0 mM for CO 2, [7] [10] turnover number (Kcat) of 2 × 10 5 s −1, and catalytic efficiency (Kcat/Km) of 5 × 10 7 M −1 s −1 comparing to other isozymes of the α-CA family of ...
Although this reaction usually proceeds very slowly, the enzyme carbonic anhydrase (which is present in red blood cells) drastically speeds up the conversion to bicarbonate and protons. [2] This causes the pH of the blood to decrease, which promotes the dissociation of oxygen from haemoglobin, and allows the surrounding tissues to obtain enough ...
Carbonic anhydrase inhibitors are a class of pharmaceuticals that suppress the activity of carbonic anhydrase. Their clinical use has been established as anti- glaucoma agents, diuretics , antiepileptics , in the management of mountain sickness , gastric and duodenal ulcers , idiopathic intracranial hypertension , neurological disorders , or ...

Carbonic anhydrases are a large family of zinc metalloenzymes that catalyze the reversible hydration of carbon dioxide. They participate in a variety of biological processes, including respiration, calcification , acid-base balance, bone resorption , and the formation of aqueous humor , cerebrospinal fluid , saliva, and gastric acid.
