Question
When all the active sites of the enzyme are occupied, how does increasing the substrate concentration affect the rate ofreaction?
The rate of reaction will slow down
The rate of reaction will become constant, and shows no increase
The rate of reaction will increase with increasing substrate concentration
The rate of reaction will become reactive in such condition
Solution
B.
The rate of reaction will become constant, and shows no increase
An increase in substrate concentration when no active sites are available would not be able to speed up the initial rate of reacton and rate of reaction will become constant.
