What is turn over number of enzyme ?a)The number of substrate molecule...
Explanation of the turnover number of an enzyme:
Definition: The turnover number of an enzyme refers to the maximum number of substrate molecules that can be converted into products by a single enzyme molecule in a given unit of time.
Key Points:
- The turnover number is a measure of the efficiency or catalytic activity of an enzyme.
- It represents the rate at which the enzyme can catalyze a reaction.
- The turnover number is expressed as the number of substrate molecules converted to products per minute per enzyme molecule.
- It is determined experimentally by measuring the initial rate of product formation under optimal conditions.
- The turnover number can vary widely depending on the specific enzyme and reaction.
- Enzymes with high turnover numbers are considered to be highly efficient catalysts.
Answer: The correct answer is A. The turnover number of an enzyme is defined as the number of substrate molecules that are converted to products in one minute by a single enzyme molecule.
