Proton-coupled electron transfer (PCET) is a fundamental process in chemistry that involves the concerted transfer of an electron and a proton, typically in an acid-base context. This process is important in various biochemical reactions, including those seen in the function of enzymes and in the processes of photosynthesis and respiration.
