They produce most of the ATP derived from the breakdown of carbohydrates and fatty acid. b. They produce most of the ATP derived from the breakdown of carbohydrates. c. They produce about half of the ATP derived … WitrynaNormally, when mitochondria are healthy, PINK1 is imported into the mitochondrial matrix through the translocase of the outer membrane (TOM) complex. In contrast, when a damaged mitochondrion exhibits a loss of mitochondrial membrane potential, PINK1 accumulates on the OMM [ 133 ], which results in the recruitment of Parkin from the …
Witryna1 lip 2014 · Due to the lack of unpaired electrons, H 2 O 2 is not a free radical but a potent oxidant that can oxidize mitochondrial components (proteins, lipids, DNA). Witryna15 cze 2008 · Both the steady-state levels of Fis1 and its in vitro insertion into isolated mitochondria were unaffected when mitochondria mutated in known import factors were analyzed. Fis1 was inserted into lipid vesicles, and importantly, elevated ergosterol contents in these vesicles inhibited this insertion.
WitrynaThe origin of most lipids imported into mitochondria is the endoplasmic reticulum, which requires interaction of these two subcellular compartments. Recently, protein complexes that are involved in membrane contact between endoplasmic reticulum and mitochondria were identified, but their role in lipid transport is still unclear.
