Pulmonary arterial hypertension (PAH) is a progressive condition that affects the heart and lungs. It is characterized by abnormally high blood pressure (hypertension) in the pulmonary artery, the blood vessel that carries blood from the heart to the lungs.
The Protein Complexes of the Electron Transport Chain. Many years of effort have been devoted to the study of the remarkable processes in the mitochondria. The electron transport chain is the final stage of aerobic respiration leading to the forming of ATP in the inner membrane of the mitochondrion. The emergent picture is that of coupled reactions through five protein structures associated with that inner membrane.
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.
