Enzymes | IGCSE and O Level Biology (0610,5090) Power Point
This engaging presentation on enzymes delves into their critical role as biological catalysts. It explains how enzymes, made of proteins, speed up chemical reactions without being consumed, using the lock and key model to illustrate enzyme-substrate interactions. The slides explore how factors like temperature, pH, enzyme and substrate concentration, and surface area influence enzyme activity, including the process of denaturation when conditions stray from the optimum. Designed for IGCSE biology students and educators, this resource provides clear visuals and detailed explanations of enzyme kinetics and metabolic regulation.
