Individual cristae within the same mitochondrion display different membrane potentials and are functionally independent. [PDF]
EMBO J, 2019 The mitochondrial membrane potential (ΔΨm) is the main driver of oxidative phosphorylation (OXPHOS). The inner mitochondrial membrane (IMM), consisting of cristae and inner boundary membranes (IBM), is considered to carry a uniform ΔΨm.

Synaptic NMDA receptor activity at resting membrane potentials [PDF]
Frontiers in Cellular Neuroscience, 2022 NMDA receptors (NMDARs) are crucial for glutamatergic synaptic signaling in the mammalian central nervous system. When activated by glutamate and glycine/D-serine, the NMDAR ion channel can open, but current flux is further regulated by voltage-dependent

Effects of membrane potentials on the electroporation of giant unilamellar vesicles. [PDF]
PLoS ONE, 2023 Living organisms maintain a resting membrane potential, which plays an important role in various biophysical and biological processes. In the context of medical applications, irreversible electroporation (IRE) is a non-thermal and minimally invasive ...

Fluctuation spectra of free and supported membrane pairs [PDF]
European Physical Journal E 23, 103-116 (2007), 2006 Fluctuation spectra of fluid compound membrane systems are calculated. The systems addressed contain two (or more) almost parallel membranes that are connected by harmonic tethers or by a continuous, harmonic confining potential. Additionally, such a compound system can be attached to a supporting substrate.

SODIUM, POTASSIUM, AND CHLORIDE TRANSPORT AND MEMBRANE POTENTIALS IN VALONIA VENTRICOSA
, 1966 1. The marine alga Valonia ventricosa regulates its ionic content by means of several ion pumps. An active extrusion of Na+ and probably an active uptake of K+ occur at the plasmalemma.
