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.
Electron transport requires oxygen directly. The electron transport chain is a series of electron carriers in the membrane of the mitochondria in eukaryotic cells. Through a series of reactions, the high energy electrons are passed to oxygen.In the process, a gradient is formed, and ultimately ATP is produced by oxidative phosphorylation.he electron transport chain is a series of electron carriers in the membrane of the mitochondria in eukaryotic cells.
