Question

enzyme activity can be determined in the following ways: check all that apply by measuring how much of the enzyme is consumed by measuring how much of the substrate is consumed by measuring how much of the product is produced determining when the amount of substrate is equal to the amount of product by measuring the ratio of enzyme to substrate concentration

Explanation:

Enzymes are catalysts and not consumed in reactions. Enzyme activity can be gauged by the rate of substrate - to - product conversion, which can be measured by substrate consumption or product formation. The equality of substrate and product amounts or the enzyme - substrate ratio doesn't directly measure activity.

Answer:

• by measuring how much of the substrate is consumed
• by measuring how much of the product is produced
