Biology Meets Quantum Mechanics: The Molecular Foundations of Bioenergetics
The dual (wave-particle) nature of matter is not usually required to describe the function of living systems. Yet, energy capture and conversion in biology rely on the delivery of electrons with sub-nanometer precision. As such, quantum phenomena take center stage. I will discuss studies that have helped to establish an understanding of how the flow of electrons is directed and regulated in living systems with fine spatial precision and, in some cases, very high energy efficiency. Physical principles emerging from these investigations allow us to understand some of the broader principles that underpin the function of nanoscale machines derived from soft-wet matter. The electron transport reactions on which I will focus are ubiquitous in living systems, powering life from archaea to bacteria to plants to us. The principles being learned, intriguing in their own right, are also motivating the design of synthetic bioinspired machinery that may begin to mimic the extraordinary function of living systems.
