-
Electron transport system (ETS)
The final metabolic pathway, which proceeds as a series of chemical reactions in the mitochondria that transfer electrons from the hydrogen atom carriers NAD and FAD to oxygen; water is formed as a by product; the electrochemical energy released by the hydrogen ions is coupled to the formation of ATP from ADP and P. The…

Ejection fraction (EF)
The percentage of end-diastolic volume that is ejected. Percentage of the total diastolic volume of blood the heart ejects as it contracts. The percentage of blood emptied from the ventricle during contraction; normal value for healthy hearts is 60-70 percent but may be much lower with valve disorders or myocardial infarction. The ratio of the…
