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.
If these electrons were all actors in cellular respiration, this would be their time to shine. The electron transport chain is the third stage of cellular respiration. Four protein complexes in the inner mitochondrial membrane form the electron transport chain.These complexes exist in a descending order of energy.Here the electron carriers come along to drop off all their electron and proton cargo that they picked up during the glycolysis and citric acid cycle stages.our protein complexes in the inner mitochondrial membrane form the electron transport chain.
