Protons are pumped by mitochondria during active electron transport correct answers outside the inner mitochondrial membrane. As electrons from NADH pass through the electron transport system, correct answers protons are pumped across the mitochondrial membrane to create a pH gradient. The first enzyme in the electron transport system is referred to as complex I, otherwise known as correct answers NADH-ubiquinone oxidoreductase. Which statement is true of the mitochondrial electron tran...

What is hemoglobin composed of? 4 heme, 4 iron, 4 globins What disorder does a defect in heme synthesis lead to? Porphyria Porphyria Deficiency in the enzymes of the porphyrin pathway leads to insufficient production of heme. The principal problem in these deficiencies is the accumulation of porphyrins, the heme precursors, which are toxic to tissue in high concentrations. What is methemoglobin? Methemoglobin is a form of hemoglobin that contains ferric [Fe3+] iron and h...
