One way of expressing the rate at which an enzyme can catalyze a reaction is to state its turnover number. The turnover number is the maximum number of substrate molecules that can be acted on by one molecule of enzyme per unit of time. The table gives the turnover number of four representative enzymes. Enzyme Ribonuclease Substrate Turnover number (per second) RNA 100 Fumarase fumarate 800 Lactate dehydrogenase lactate 1000 Urease urea 10,000 How many molecules of fumarate can one molecule of fumarase act on in 12.4 min? fumarate molecules:
