The catalytic efficiency of two different enzymes can be compared by the:
- the Km value
- the pH optimum value
- formation of the product
- molecular size of the enzyme
The Correct Option is A
Solution and Explanation
The Km value, also known as the Michaelis-Menten constant, is a measure of the substrate concentration at which an enzyme reaches half of its maximum catalytic activity. Lower Km values indicate higher affinity of the enzyme for the substrate and, often, greater catalytic efficiency. Therefore, comparing the Km values of two enzymes can provide insights into their relative catalytic efficiencies.
So, the correct option is (A): the Km value

Enzymes - Biology
Enzymes are proteins that help accelerate metabolism or the chemical reactions in our bodies. They build some substances and decompose others. All living creatures have enzymes.
Our bodies naturally build enzymes. But enzymes are also in mass produce products and food.
One of the most important roles of enzymes is to succor digestion. The process of turning the food that we eat into energy is called digestion. For instance, there are enzymes in our saliva, pancreas, stomach, and intestines. They decompose fats, proteins, and carbohydrates. Enzymes make use of these nutrients for growth and cell repair.
