Biomolecules Question 134
Assertion : Enzyme substrate complex remains throughout the reaction. Reason : The greater the affinity of the enzyme for a substrate, the higher is the catalytic efficiency.
Options:
A) If both the assertion and the reason are true and the reason is a correct explanation of the assertion
B) If both the assertion and reason are true but the reason is not a correct explanation of the assertion
C) If the assertion is true but the reason is false
D) If the assertion is false but reason is true

Answer:
Correct Answer: D
Solution:
The enzyme-substrate complex is short lived.
The substrate is changed into products.
The products remain complexed with the active site of the enzyme for a brief period.
They soon separate and the active site is freed to perform another catalytic act.
Enzymes activity depends upon their affinity for substrates.
If turnover number of enzyme is higher, then enzymes show high affinity towards substrate.
The number of substrate molecules converted per minute by a molecule or enzyme is called turnover number.
