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.
The electron transport chain is the path in which the electrons travel during cellular respiration. The electron transport system is the set of proteins and other cellular câ¦omponents that are involved in the electron transport chain. For example, the both aerobic and anaerobic organisms, there are different electron transport systems and this influences the path electrons take.
