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.
In eukaryotes, an important electron transport chain is found in the inner mitochondrial membrane where it serves as the site of oxidative phosphorylation through the use of ATP synthase. It is also found in the thylakoid membrane of the chloroplast in photosynthetic eukaryotes.n mitochondria, it is the conversion of oxygen to water, NADH to NAD + and succinate to fumarate that are required to generate the proton gradient. Electron transport chains are major sites of premature electron leakage to oxygen, generating superoxide and potentially resulting in increased oxidative stress.
