One of the many remarkable enzymes in the human body is carbonic anhydrase, which catalyzes the interconversion of carbonic acid with carbon dioxide and water. If it were not for this enzyme, the body could not rid itself rapidly enough of the CO₂ accumulated by cell metabolism. The enzyme catalyzes the dehydration (release to air) of up to 107 CO₂ molecules per second. Part A Which component of this description corresponds to the term enzyme? Spell out the full name of the enzyme. Submit Part B Request Answer What is the chemical formula for the component of this description that corresponds to the term substrate? Express your answer as a chemical formula. Part C ΑΣΦ ? DA chemical reaction does not occur for this question. Submit Request Answer Which component of this description corresponds to the term turnover number? Express your answer using one significant figure. ΫΠ ΑΣΦ ? CO₂ molecules per second
