The rate of biochemical reaction can changes in the presence of a special type of proteins is known as enzymes.

Answer to Problem 55A

The molecule acted on by an enzyme is termed as substrate.

Explanation of Solution

Enzyme is composed of proteins. This is a substance that performed as catalyst and maintaining the rate of chemical reactions proceed without used in the process. The enzyme act on a molecule is termed as substrate, and formed a complex that is enzyme substrate complex and converted into product.

Conclusion

In the function of enzymes important terms are as substrate, enzyme and enzyme substrate complex (ES) and product.
