When NADH moves through the transport chain about 10 H+ ions ... in the cytosol and NADH can’t pass through the membrane into the mitochondria. Because it can’t deliver the electrons to ...

Based on these differences, organisms are divided into two groups ... molecules, NADH and FADH 2, which are rich in electrons. The two molecules move to the inner mitochondrial membrane and ...

The bacteria evolved into mitochondria, thus endowing the host ... as adenosine triphosphate (ATP), by means of the electron-transport chain and the oxidative-phosphorylation system (the ...

In the electron transport chain, electrons are transferred from NADH and FADH2 to O 2 and the incremental release of energy is used to pump protons (H +) into the space between the mitochondria ...

"Until a few years ago, we were sure that mitochondria ... I of the electron transport chain. Complex I transfers electrons (initially derived from food) from the coenzyme NADH (nicotinamide ...
