WebThe two NADH produced in the cytoplasm produces 2 to 3 ATP each (4 to 6 total) by the electron transport system, the 8 NADH produced in the mitochondriaproduces three ATP each (24 total), and the 2 FADH2adds its electrons to the electron transport system at a lower level than NADH, so they produce two ATP each (4 total). WebThe TCA cycle is named for tricarboxylic acids (TCA) because citric acid (or citrate) and isocitrate, the first two intermediates that are formed, are tricarboxylic acids.
