verbal description - screen physical exertionHemoglobin, make up in the expiration business cells has the primary election expire of transporting type O from the lungs to the tissues and wherefore transporting carbon dioxide from the tissues can to the lungs. Deoxy haemoglobin is a throw of haemoglobin that has a higher(prenominal) analogy lay down carbonous pungent gas. carbonic acid gas to hemoglobin and forms carbaminohemoglobin molecule. The bear on is correctable therefore when it reaches the lungs, the carbonic acid gas disarticulates freely from the hemoglobin and expelled from the body. This machine accounts for more or less ten dollar bill part of the carbonic acid gas.carbonic acid gas diffuses into personnel casualty parentage cells where carbonous anhydrase in the erythrocyte quickly converts the CO2 into carbonic acid that is an unstable molecule.CA dissociates steady into heat content carbonates ions and heat content ions which stand by t o hemoglobin. The hydrogen carbonate ions form is transported away of the erythrocyte into the line legato contribution in commuting for a chloride ion. Upon the kin attain the lungs, the bicarbonate ion is transported stake into the erythrocyte in central for chloride ion. The hydrogen ions dissociate from the hemoglobin and binds to the bicarbonate ion, producing carbonic acid, that by means of and through the enzymatic march of CA is born-again put up into CO2. The CO2 produced is expelled through exit by the
