A student was performing an experiment to understand the enzyme-substrate reaction. The student measured the formation of coloured product using a colorimeter. The student plotted the graph below which shows the reaction rate versus the substrate concentration.

Following interpretations were drawn by the student :
a) The higher concentration of substrate acts as anenzyme inhibitor.
b) It is a sigmoidal curve with sharp transition from low to high reaction rates over the increasing substrate concentration.
c) The curve reaches a plateau and does not further increase with increasing substrate concentrations due to saturation of enzyme with the substrate.
Choose which of the "interpretations of the graph are correct.

Options

A. A and B
B. A arid C
C. B only
D. B and C

Answer

B

Explanation

The given graph states that by increasing the concentration of substrate creates saturation in the enzyme-substrate reaction. As the higher concentration of substrate acts as an enzyme inhibitor so, the curve reaches a plateau and does not increase further.
