The word "matrix" stems from the fact that this space is viscous, compared to the relatively aqueous cytoplasm. The mitochondrial matrix contains the mitochondrial DNA , ribosomes , soluble enzymes , small organic molecules, nucleotide cofactors, and inorganic ions . [1]
Membranoproliferative glomerulonephritis (MPGN) is a type of glomerulonephritis caused by deposits in the kidney glomerular mesangium and basement membrane thickening, [2] activating the complement system and damaging the glomeruli. MPGN accounts for approximately 4% of primary renal causes of nephrotic syndrome in children and 7% in adults. [3]
There are four groups of intramembrane proteases, distinguished by their catalytic mechanism: [5]. Metalloproteases: Site-2 protease (S2P) and S2P-like proteases [9]; Aspartyl proteases: this group includes presenilin, the active subunit of gamma secretase [10] [11] and signal peptide peptidases (SPPs) and SPP-like proteases, which are distantly related to presenilin but have opposite membrane ...
Voltage-gated ion-channels are usually ion-specific, and channels specific to sodium (Na +), potassium (K +), calcium (Ca 2+), and chloride (Cl −) ions have been identified. [1] The opening and closing of the channels are triggered by changing ion concentration, and hence charge gradient, between the sides of the cell membrane.
Protein anabolism is the process by which proteins are formed from amino acids. It relies on five processes: amino acid synthesis, transcription, translation, post translational modifications, and protein folding.
In contrast, intramembranous ossification takes place directly beneath the periosteum, adjacent to the broken bone’s ends. [10] [12] A schematic of endochondral fracture, where B shows the location of both endochondral and intramembranous ossification.
Simplified structure of a mitochondrion. The intermembrane space (IMS) is the space occurring between or involving two or more membranes. [1] In cell biology, it is most commonly described as the region between the inner membrane and the outer membrane of a mitochondrion or a chloroplast.
