The respiration of cells and mitochondria of porin deficient yeast mutants is coupled - Michejda, Guo, et al. - 1990 () Citation Context ...curs through both mitochondrial membranes. These conclusions are in agreement with the bioenergetic characteristics of mitochondria of the YVDAC1-depleted ...
In mitochondria, pyruvate is oxidized to acetyl-CoA, and controlled "combustion" generates energy equivalent to two ATP molecules. The overall sum of the citric acid cycle can be represented as:Acetyl-CoA + 3 NAD+ + FAD + GDP + Pi + 2 H2O → CoA-SH + 3 NADH + 3 H+ + FADH2 + ...
[17] to inhibit anabolic processes and stimulate catabolism. One of the energy substrates in cancer cells is proline, which is derived from protein degradation, mainly collagen. Proline is degraded in mitochondria by proline dehydrogenase/proline oxidase (PRODH/POX) [18,19]. The enzyme is up...
Chloroplasts are similar tomitochondria, the energy powerhouses of cells, in that they have their own genome, or collection of genes, contained within circular DNA. These genesencode proteinsthat are essential to the organelle and to photosynthesis. ...
Finally, rotenone and antimycin A (R/A), inhibitors of complexes I and III of the ETC, respectively, completely block mitochondrial respiration, and thus any component of the OCR derived from the mitochondria. What remains after R/A treatment indicates the non-mitochondrial respiration (Fig. 2a...
These rates give an estimate of whether changes in total respiration can ultimately affect the ability of the mitochondria to use the proton-motive force to synthesize ATP. In ODQ- or L-NAME- treated cells, the ratio of oligomycin-resistant to maximal respiration was reduced, whereas the ratio...
Mitochondria are organelles that produce energy for the cell. They are where the cell’s aerobic respiration takes place. Aerobic respiration transfers energy from glucose (a simple sugar). It requires oxygen to take place. The number of mitochondria in a cell depends on the function of the cel...
Glutathione is essential formaintaining healthy cellular mitochondria. Damaged or malfunctioning cellular mitochondria are part of the cancer process. This occurs when exposure to toxins and unhealthy cellular terrain combine to trigger a cellular defensive response. During this process healthy cells become ...
In eukaryotes, de novo Fe–S biogenesis takes place within mitochondria and relies on proteins that are highly conserved, with homologues found in bacteria and yeast. During de novo Fe–S biogenesis, a cysteine desulfurase complex, consisting of NFS1 and ISD11, provides the inorganic sulfur and...
