Enzymes (e.g., DNA polymerase)

Enzymes are biological catalysts that speed up chemical reactions in the body. For example, DNA polymerase is an enzyme that helps copy DNA by adding nucleotides to create a new strand during cell division. It ensures the process is accurate and efficient. Think of enzymes like tiny machines that facilitate specific tasks, making complex processes happen quickly and smoothly. Without enzymes like DNA polymerase, essential biological functions—such as DNA replication—would occur too slowly or not at all. They are vital for maintaining life by enabling vital biochemical reactions efficiently.
