Enzymes, such as the one shown in the picture, work by fitting onto the substrate molecule like a lock-and-key action. Which statement is true, with regard to the enzyme and the substrate?

The enzyme weakens chemical bonds in the substrate and catalyzes a change into the product. The enzyme itself remains unchanged.

Answer;

A)  The enzyme weakens chemical bonds in the substrate and catalyzes a change into the product. The enzyme itself remains unchanged.

Explanation;

  • Enzymes are biological catalysts that speed up chemical reactions. Enzymes catalyze or speed up a reaction by binding to a substrate using its active site.
  • The active site of an enzyme is suited to bind a particular substrate, that is why enzymes are known to substrate specific.
  • The binding of the substrate to the enzyme results to changes in the distribution of electrons in the chemical bonds of the substrate and consequently leads to  reactions that lead to the formation of products.
