What does MOM mean in BRITISH MEDICINE

Mitochondrial Outer Membrane (MoM) is part of the internal membrane system that forms the boundary of a mitochondrion. It separates the organelle's interior compartment from the cytoplasm and creates an environment inside the organelle for energy production. The MoM is composed of proteins, lipids and phospholipids arranged in a structure known as a bilayer membrane.

The Mitochondrial Outer Membrane helps with regulating energy production in the cell by controlling how metabolites move into and out of the mitochondria. It also plays a role in maintaining proper calcium levels for cellular processes and stimulating other components of the cell.

The proteins present in Mitochondrial Outer Membrane are TIM23 complex, voltage-dependent anion channel (VDAC), porin OMI, adenine nucleotide translocator (ANT) and others such as mitochondrial heat shock protein 70, tetraspanins family members, ATP synthase, cytochrome c oxidase, superoxide dismutase etc.

The inner mitochondrial membrane contains larger spaces within it which contain respiratory chain enzymes that produce ATP whereas the outer mitochondrial membrane has smaller protein channels allowing metabolites to enter or leave of its interior network. Moreover, Inner mitochondrial membrance has additional cristae while outer mitochondrial membrane does not have any cristae.

Transmembrane potential affects Mitochondria by increasing their efficiency for ATP production and providing directionality to electron transport chain reactions occurring within it. This potential is maintained due to unequal distribution of protons across both sides of inner mitochondria membranes which causes proton transport through specific protein complexes like Complex I , Complex III & Complex IV otot take place across it.

Yes, ionic species including protons can freely pass through Mitochondrial Outer Membranes due to presence of specialized proteins present on its surface such as Voltage Dependent Anion Channels(VDAC) & Porin OMI which allows them to filter small molecules like ions through them with ease.

Porin OMI plays important roles in metabolism by allowing free movement of small metabolite molecules like substrates , ions etc into & out fromMitochrondia interior & cytoplasm respectively resulting in efficient energy processsing within cells via efficient metabolic pathways.
