Chapter 21, Problem 25A

Interpretation Introduction

Interpretation:

The specific portion of the enzymes for catalysis needs to be explained.

Concept introduction:

An enzyme is composed of proteins. This is a substance that performed as a catalyst and catalyst and maintaining the rate of chemical reactions proceeds without used in the process.

The enzymes are fixed for a particular reaction.

Answer to Problem 25A

The name of a specific portion of the enzyme is an active site, where the catalysis occurs.

Explanation of Solution

The proteinaceous compound is enzymes function as a catalyst for the biochemical reaction. They act on the substrate and formed a complex that is enzyme-substrate complex and after interactions of a particular site with the enzyme is called the active center. The enzyme and substrate form a complex at the active center. So enzymes are specific for particular molecules.

Conclusion

The enzyme joined with the substrate to change the speed of the biochemical reaction. Every enzyme is specific for a particular substrate according to its specific active site.
