Question

The given graph shows the effect of substrate concentration on the rate of reaction of the enzyme green gram-phosphatase. What does the graph indicate?

• A. The rate of enzyme reaction is directly proportional ot the substrate concentration
• B. The presence of an enzyme inhibitor in the reaction mixture
• C. Formation of an enzyme-substrate complex
• D. At higher substrate concentration, the pH increase

Answer 1

The correct option is B The presence of an enzyme inhibitor in the reaction mixture

In given graph, the initial rate of enzymatic reaction increases but after some time, it begins to slow down due to the presence of an enzyme inhibitor.
