Unformatted text preview: + + FADH 2 to produce ATP ii. regenerate NAD + and FAD b. occurs in inner mitochondrial membrane c. NADH act as reducing agentthat is, it gives electrons to the respiratory chain d. Electrons are passed through a series of molecules in the inner mitochondrial membrane e. Protons are transported through active transport to intermembrane space of mitochondria, creating a concentration gradient f. Protons pass through ATP synthase (enzyme) in the direction of the gradient, and this energy is used to synthesize ATP from ADP and P i g. 1 molecule of NADH+H + forms 3 ATP in the respiratory chain VI. Fermentation a. Requires no O 2 b. Pyruvate oxidized to either ethanol or lactic acid c. No ATP produced d. Uses NADH+H + from glycolysis to reduce pyruvate, regenerating NAD + e. When cells use fermentation in place of cellular respiration, rate of glycolysis speeds up so that ATP is sufficient...
