Mitochondria are the powerhouses of our cells, generating energy that supports life. A giant molecular proton pump, called complex I, is crucial: It sets in motion a chain of reactions, creating a ...

Proton-coupled electron transfer (PCET) reactions play a vital role in a wide range of chemical and biological processes. Recent advances in the theory of PCET will be presented. The quantum ...

Protein engineering makes coupling visible. The team manipulated the hydrogenases in such a way that the proton transfer was significantly slower, but hydrogen could still be converted.

Proton transfer in proteins is directly influenced by electron spin in chiral environments, indicating that this process involves quantum effects rather than being purely chemical.

Electron movement—what scientists call electron transfer ... small protein electron carriers," explained Kramer, an expert in bioenergetics and photosynthesis electron and proton transfer ...

The synergistic intensification of molecule-electron-proton transfer is of vital importance in fortifying the mass/energy exchange in EPCS. view more . Credit: Chinese Journal of Catalysis.
