What role do enzymes play in cell processes?

• A. They provide energy for failed reactions
• B. They increase the rate of chemical reactions
• C. They block cellular processes
• D. They produce waste products

Answer: (B)

Enzymes are crucial biological catalysts that speed up chemical reactions within cells. By lowering the activation energy required for these reactions, enzymes facilitate processes such as digestion, metabolism, and DNA replication. This acceleration allows the necessary biochemical reactions to occur more efficiently and rapidly under physiological conditions, which is essential for maintaining life. The contribution of enzymes to biological processes is fundamental; without them, many reactions would occur too slowly to sustain life. Therefore, their primary role is not to provide energy or block processes but to enhance the speed and efficiency of reactions crucial to the functioning of the cell. Additionally, while enzymes are involved in various processes, they do not produce waste products as a primary function; rather, they help convert substrates into products that may or may not be waste.
