The graph shows the effect of temperature on the rate at which the enzyme in a biological washing powder digests and removes fruit juice stains. Which statements explain the shape of the graph at temperatures higher than X? I. Bonds are broken between the R groups of the amino acids in the polypeptide chains of the enzyme. II. There are more collisions between the enzyme and its substrate. III. The tertiary structure
Options
- AI, II and II
- BI, II and IV
- CI, III and IV
- DII, III and IV
Correct answer
C. I, III and IV
Step-by-step solution
Enzymes generally function in a narrow range of temperature. Each enzyme shows its highest activity at a particular temperature called optimum temperature. Low temperature preserves the enzyme in a temporarily inactive state whereas high temperature destroys enzymatic activity because proteins are denatured by heat.
