- A proton gradient is created during the electron transport chain using the energy released from the oxidation of NADH and FADH2. The protons then cross the membrane through ATP synthase down their electrochemical gradient, and ATP is produced.

- In 2012, an Illinois man was killed by cyanide poisoning after he won a million dollars in the lottery. Cyanide is a lethal poison because it interferes with the electron transport chain in mitochondria. What effect would cyanide have on cellular respiration? (a) Glycolysis, the Krebs cycle, and oxidative phosphorylation would all be inhibited. (b) The Krebs cycle would be inhibited, but oxidative phosphorylation would not. (c) Oxidative phosphorylation would be inhibited. (d) Glycolysis, the Krebs cycle, and oxidative phosphorylation would all be stimulated.arrow_forward1) Using the equations for cellular respiration and photosynthesis, explain what makes one pathway overwhelmingly anabolic and the other overwhelmingly catabolic. 2) Write out the equation for cellular respiration in words. What molecule is reduced and which is oxidized? 3) What goes into, and what comes out of the four steps of cellular respiration (glycolysis, pyruvate oxidation, the citric acid cycle, electron transport chain)? 4) Differentiate between and describe the three types of phosphorylation as discussed in the lecture and additional narrated whiteboard work available on in your "video material" for the week. You should go into detail here. Go into EXTREME detail with regard to oxidative phosphorylation.
