- 7-13 Why are reactions between ions in aqueous solution generally much faster than reactions between covalent molecules?The expected reaction intermediate in the following reaction is? H,SO4, H2O HØSO4One of the many remarkable enzymes in the human bodyis carbonic anhydrase, which catalyzes the interconversionof carbon dioxide and water with bicarbonate ionand protons. If it were not for this enzyme, the body couldnot rid itself rapidly enough of the CO2 accumulated bycell metabolism. The enzyme catalyzes the dehydration(release to air) of up to 107 CO2 molecules per second.Which components of this description correspond to theterms enzyme, substrate, and turnover number?
