Electron Transport Chain (ETC) Four protein complexes in the inner mitochondrial membrane form the electron transport chain. -Here the electron carriers come along to drop off all their electron and proton cargo that they picked up during the glycolysis and citric acid cycle stages. - NADH + H+ and FADH2 become oxidized, donating electrons to the first and second protein complex respectively. The independent variable in an experiment is the one thing that is varied between experimental grou...

The independent variable in an experiment is the one thing that is varied between experimental groups. The effect of the independent variable is typically what is being analyzed. In the situation described, the independent variable is the method by which the passage is presented to the test subjects, either aurally or visually. continuous variation Human skin color, height, and weight are influenced by many genes as well as environmental factors. When the frequency in a population of differen...
