Mode of action of enzymes — practice question

The number of substrate molecules that one enzyme molecule can turn into product in 1 second is known as the turnover number. It is measured when the conditions are optimum for that particular enzyme-catalysed reaction. Catalase: 2 800 000 Carbonic anhydrase: 600 000 Phosphatase: 971 Protease: 100 By what factor is catalase faster than phosphatase in converting substrate into product?
