Explore the fascinating science of muscle structure and function in this 59-minute Christmas Lecture from 1980. Discover how muscles work as complex protein-based engines that convert chemical energy into mechanical work, with particular focus on the large breast muscles of chickens and turkeys that make them such popular food choices. Learn about groundbreaking research conducted using electron microscopy that has revealed the intricate construction of muscle tissue and examine current theories about muscle mechanics. Delve into the molecular composition of muscles, understanding how protein molecules organize and function to create movement. Part of Sir David Phillips' acclaimed 1980 Christmas Lecture series examining the fundamental question of which came first - DNA or proteins - this lecture demonstrates the complexity and importance of proteins in biological systems through engaging demonstrations and scientific explanations recorded at The Royal Institution.
