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 location of the electron transport system depends on the cell type. The electron transport system is embedded in the inner membrane of the mitochondria for animal, plant and fungus cells. The electron transport systemis also in the thylakoid membrane of chloroplasts in plant cells.
