Enzymes | Confused

Enzymes are the unsung heroes of biology, protein molecules that act as biological catalysts, dramatically accelerating the rate of chemical reactions essential for life. Without them, processes like digestion, DNA replication, and muscle contraction would occur too slowly to sustain us. Their specificity is remarkable; each enzyme typically catalyzes only one or a very small number of reactions, fitting substrates into precisely shaped active sites like a lock and key. The discovery and understanding of enzymes, particularly by Eduard Buchner in the late 19th century who demonstrated cell-free fermentation, revolutionized biochemistry and medicine, paving the way for industrial applications and therapeutic interventions.
