Abstract
Oxidative phosphorylation (OxPhos) is the energy-transfer process that generates most of our ATP, fueled by proton and electrical gradients across the inner mitochondrial membrane. A new surprising finding by Hernansanz-Agustín et al. demonstrates that between one-third and half of this gradient is attributable to Na+, transported in exchange for protons within complex I.
期刊介绍:
For over 40 years, Trends in Biochemical Sciences (TIBS) has been a leading publication keeping readers informed about recent advances in all areas of biochemistry and molecular biology. Through monthly, peer-reviewed issues, TIBS covers a wide range of topics, from traditional subjects like protein structure and function to emerging areas in signaling and metabolism. Articles are curated by the Editor and authored by top researchers in their fields, with a focus on moving beyond simple literature summaries to providing novel insights and perspectives. Each issue primarily features concise and timely Reviews and Opinions, supplemented by shorter articles including Spotlights, Forums, and Technology of the Month, as well as impactful pieces like Science & Society and Scientific Life articles.
