Proton Transport Chains in Glucose Metabolism: Mind the Proton [PDF]

Frontiers in Neuroscience, 2018
The Embden–Meyerhof–Parnas (EMP) pathway comprises eleven cytosolic enzymes interacting to metabolize glucose to lactic acid [CH3CH(OH)COOH]. Glycolysis is largely considered as the conversion of glucose to pyruvate (CH3COCOO-). We consider glycolysis to

Interconnected roles of mitochondrial carrier proteins ANT, PiT, and UCPs in proton transport [PDF]

Frontiers in Molecular Biosciences
IntroductionAdenine nucleotide translocase (ANT), phosphate translocase (PiT), and uncoupling proteins (UCPs), all integral to oxidative phosphorylation, are among the carrier proteins of the mitochondrial inner membrane (MIM).

Fatty Acid-Activated Proton Transport by Bisaryl Anion Transporters Depolarises Mitochondria and Reduces the Viability of MDA-MB-231 Breast Cancer Cells [PDF]

Biomolecules, 2023
In respiring mitochondria, the proton gradient across the inner mitochondrial membrane is used to drive ATP production. Mitochondrial uncouplers, which are typically weak acid protonophores, can disrupt this process to induce mitochondrial dysfunction ...

Proton transport from the antimatter factory of CERN. [PDF]

Nature
Abstract The antiproton is a basic constituent of antimatter and required for stringent matter-antimatter comparisons to test the fundamental charge-parity-time (CPT) reversal invariance in the Standard Model of particle physics (1). Using low energy antiprotons, only available at the antimatter factory (AMF) located at CERN (2), such tests ...

Efficient proton transport modelling for proton beam therapy and biological quantification. [PDF]

J Math Biol
Abstract In this work, we present a fundamental mathematical model for proton transport, tailored to capture the key physical processes underpinning Proton Beam Therapy (PBT). The model provides a robust and computationally efficient framework for exploring various aspects of PBT, including dose delivery, linear energy transfer, treatment ...

Interfacial and Internal Proton Conduction of Weak-acid Functionalized Styrene-based Copolymer with Various Carboxylic Acid Concentrations

Electrochemistry, 2021
Investigation of interfacial proton transport is necessary to elucidate biological systems. As commonly found in biomaterials, the carboxylic acid group was proven to act as a proton-conducting group.

Contribution of the Collective Excitations to the Coupled Proton and Energy Transport along Mitochondrial Cristae Membrane in Oxidative Phosphorylation System

Entropy, 2022
The results of many experimental and theoretical works indicate that after transport of protons across the mitochondrial inner membrane (MIM) in the oxidative phosphorylation (OXPHOS) system, they are retained on the membrane–water interface in ...

Proton Gradients and Proton-Dependent Transport Processes in the Chloroplast [PDF]

Frontiers in Plant Science, 2016
Proton gradients are fundamental to chloroplast function. Across thylakoid membranes, the light induced -proton gradient is essential for ATP synthesis. As a result of proton pumping into the thylakoid lumen, an alkaline stromal pH develops, which is required for full activation of pH-dependent Calvin Benson cycle enzymes.
