Pulmonary arterial hypertension (PAH) is a progressive disease caused by narrowing or tightening (constriction) of the pulmonary arteries, which connect the right side of the heart to the lungs.
In bacterial cells, the electron transport system is located in the. A. cell membrane. B. mitochondria. C. chloroplasts. D. ribosomes.E. cytoplasm.n bacterial cells, the electron transport system is located in the. A. cell membrane. B. mitochondria. C. chloroplasts. D. ribosomes.
Electron transport and oxidative phosphorylation occur in the mitochondrion, the cell's power plant. The citric acid enzymes are housed there as is pyruvate dehydrogenase, enzymes for fatty acid oxidation, and all of the enzymes and proteins of the electron transport/oxidative phosphorylation system.eduction of molecular oxygen. Overview: The electron transport system (ETS) is a mechanism for capturing in the form of ATP, energy from the transfer of electrons from NADH and FADH2 to O2. During this process, the mitochondrion expels protons, creating a pH gradient across the mitochondrial membrane.
