Do Magnesium Ions Have Similar Effects as Calcium Ions on Resting Membrane Potential? [PDF]
MembranesMaintaining a membrane electrical potential of biological cells is a dynamic process, as some cells have a continually changing potential, like pacemaker cells, while other cells may function with large or small changes in the membrane potential ...

Measuring mitochondrial membrane potential. [PDF]
EMBO JMitochondrial function determines the balance between health and disease, making understanding their bioenergetics an increasingly important focus across biomedical research. Among the most relevant and accessible measures of mitochondrial function in intact cells is the mitochondrial membrane potential (ΔΨm), typically determined with commercially ...

The Multi-Conductivity Clausius–Mossotti Factor as an Electrophysiology Rosetta Stone: Dielectrophoresis, Membrane Potential and Zeta Potential [PDF]
MicromachinesDielectrophoresis (DEP) has been used for decades to estimate the passive electrical properties of cells. However, the body of work on cell electrophysiology derived from Clausius–Mossotti analysis of DEP-derived data pales to insignificance against the ...

Frontiers in Plant Science, 2022 The transthylakoid membrane potential (ΔΨm) is essential because it can drive the ATP synthesis through the CF0–CF1 type of ATP-synthase in chloroplasts as an energetic equivalent similar to ΔpH.

Deciphering the Role of Ion Channels in Early Defense Signaling against Herbivorous Insects
Cells, 2021 Plants and insect herbivores are in a relentless battle to outwit each other. Plants have evolved various strategies to detect herbivores and mount an effective defense system against them.

Mitochondrial membrane potential [PDF]
Analytical Biochemistry, 2018 The mitochondrial membrane potential (ΔΨm) generated by proton pumps (Complexes I, III and IV) is an essential component in the process of energy storage during oxidative phosphorylation. Together with the proton gradient (ΔpH), ΔΨm forms the transmembrane potential of hydrogen ions which is harnessed to make ATP.

Calcium‐ and voltage‐driven atrial alternans: Insight from [Ca]i and Vm asynchrony
Physiological Reports, 2023 Cardiac alternans is defined as beat‐to‐beat alternations in contraction strength, action potential duration (APD), and Ca transient (CaT) amplitude. Cardiac excitation–contraction coupling relies on the activity of two bidirectionally coupled excitable ...
