What is meant by the statement "Enzymes are biological catalysts"? Enzymes produce products useful-for biology. Enzymes speed up the chemical reactions in living cells. Enzymes produce biological organisms. Enzymes are products of biological systems.

The correct answer is: Enzymes speed up the chemical reactions in living cells.<br /><br />Explanation: Enzymes are proteins that act as catalysts in biological systems. A catalyst is a substance that increases the rate of a chemical reaction without being consumed or altered itself. Enzymes speed up chemical reactions by lowering the activation energy required for the reaction to occur. This allows the reaction to proceed faster and more efficiently than it would without the enzyme. Enzymes are essential for many biological processes, such as digestion, metabolism, and DNA replication. They are not products of biological systems, nor do they produce biological organisms. While enzymes do produce products as a result of the reactions they catalyze, these products are not necessarily useful for biology in all cases.
