The curve given below shows enzymatic activity with relation to three conditions (pH, temperature and substrate concentration). What does the two axis (x and y) represent?

Step-by-step solution

In the given curve the temperature and enzyme activity relation is shown. Enzymes generally function in a narrow range of temperatures. Each enzyme shows its highest activity at a particular temperature called the optimum temperature. Activity declines both below and above the optimum value. Low temperature preserves the enzyme in a temporarily inactive state whereas high temperature destroys enzymatic activity because proteins are denatured by heat.
