idk if I'm actually heading the right direction with this I was completely wrong on the front side of this ..having a hard time understanding the whole process
All of the enzymatic steps in the oxidative break- down of carbohydrates, fats and amino acids in aerobically respiring cells converge at this final stage of cell respiration. Similar to Figure 3.18 electrons flow from catabolic intermediates to energy for the formation of ATP (from ADP + which yields The electron transport chain (ETC) (shown above) is a linked series of proteins located on the naittodnnd Our current understanding of ATP synthesis in the mitochondria is based on a hypothesis introduced by Peter Mitchell in 1961, called the Chemiosmotic Theory. This theory describes how the differences in [H'1 (proton concentration) across the inner mitochondrial membranes are key in energy transduction. This theory provides insight into the process of Figure 3.19 Steep H concentratiorn gradient is established Double phospholipid bi- layer of mitochondria 1.

1. what is the effect of increased level of hydrogen ions in the intermembrane space of mitochondria?
The intermembrane space is chemically similar to cytosol, but includes a large amount of small proteins as well. As electrons move down the proteins in the electron transport chain, the electrons lose energy to bring H+ ions from the mitochondrial matrix into theintermembrane space. This increased level of H+ ions Increases ATP production in the mitochondria.
