RESEARCH FIELD

Bioenergetics

Bioenergetics investigates how living systems convert, store, and utilise energy, focusing on the molecular mechanisms of mitochondrial respiration, photosynthesis, and ATP synthesis. Researchers study the structure and function of respiratory chain complexes, the light reactions and carbon fixation pathways of chloroplasts, proton motive force generation, and the thermodynamics of metabolic pathways. The field has profound implications for understanding ageing, metabolic disease, cancer cell metabolism, and plant productivity improvement. Core subfields include mitochondrial physiology, chemiosmosis, metabolic flux analysis, biofuel cell design, and the energetics of microbial fermentation. Key technologies include Seahorse XF analysers for real-time oxygen consumption measurement, cryo-electron microscopy of respiratory supercomplexes, 13C stable isotope metabolic flux analysis, and patch-clamp electrophysiology of membrane channels. Bioenergetics is funded by cancer research institutes, diabetes foundations, basic biology programmes, and the renewable energy sector interested in artificial photosynthesis.
