The correct Answer is:
To solve the question regarding the catalytic action of an enzyme, we will analyze the options provided and determine the correct answer based on our understanding of enzyme function. ### Step-by-Step Solution: 1. **Understanding Enzymes**: Enzymes are biological catalysts that speed up chemical reactions in living organisms. They are proteins that have specific structures allowing them to perform their catalytic functions. 2. **Specificity of Enzymes**: Enzymes are known for their high specificity. This means that each enzyme typically catalyzes only one type of reaction or a set of closely related reactions. This specificity is due to the unique shape of the enzyme's active site, which only fits certain substrate molecules. 3. **Analyzing the Options**: - **Highly Specific**: This option aligns with our understanding of enzymes. They are indeed highly specific to the substrates they act upon. - **Non-Specific**: This option contradicts the known behavior of enzymes. Enzymes are not non-specific; they do not act on just any substrate. - **Does Not Depend on the Nature of Substrate**: This is incorrect. The nature of the substrate is crucial for enzyme activity, as the enzyme's active site must complement the substrate. - **Common for Many Biochemical Reactions**: While some enzymes may catalyze similar reactions, they are not common for many different biochemical reactions. Each enzyme is specific to a particular reaction or a closely related set of reactions. 4. **Conclusion**: Based on the analysis of the options, the only correct statement is that the catalytic action of an enzyme is **highly specific**. ### Final Answer: The catalytic action of an enzyme is **highly specific**. ---

Arrange the steps of catalytic action of an enzyme in order and select the correct option I. The enzyme releases the products of the reaction and the enzyme is free to bind to another substrate II. The active site of enzyme is in close proximity of the substrate and breaks the chemical bonds of the substrate III. The binding of substrate induces the enzyme to alter its shape fitting more tightly around substrate. VI. The substrate binds to the active site of the enzyme
