D. Proteins
🧠 Explanation:
Enzymes are primarily made of proteins and act as catalysts to speed up biochemical reactions, like digestion or metabolism. They are essential for life, enabling processes like breaking down food or repairing tissues. This concept is a cornerstone in biochemistry, vital for students and researchers studying how the body functions at a molecular level. Enzymes’ specificity and efficiency make them a key focus in medical and biological sciences, with applications in drug development and health diagnostics. Understanding enzymes helps explain how living organisms maintain vital processes, making it a critical topic in science education.
