Bioenergetics is the study of energy flow and transformation in biological systems, focusing on how cells acquire, convert, store, and utilize energy to drive metabolic processes. It encompasses the thermodynamics and kinetics of biochemical reactions, including ATP synthesis, redox reactions, and proton motive force generation across biological membranes. Central topics include oxidative phosphorylation, photosynthetic energy conversion, substrate-level phosphorylation, and the coupling of catabolic and anabolic pathways. Bioenergetics provides quantitative frameworks (e.g., Gibbs free energy, redox potentials, chemiosmotic theory) to analyze how cellular structures such as mitochondria, chloroplasts, and bacterial membranes support energy transduction and maintain nonequilibrium steady states required for life.
Humans develop at a slower rate than other mammalian species, like mice, but scientists are still trying to understand the molecular basis of these differences. Now, researchers from the Ebisuya Group at EMBL Barcelona and ...
