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.
During aerobic cell respiration most of the energy isproduced during:(a) Krebs cycle (b) Glycolysis(c) Fermentation (d) ATP→ ADP(e) Electron transport chain reactions
In aerobic respiration when is carbon dioxide produced?
(a) when oxygen is used as the final electron acceptor in oxidative phosphorylation (b) glycolysis (c) during substrate level phosphorylation (d) Krebs cycle (e) when hydrogen is pumped across the inner membrane of the mitochondria

- Luckily, protons (a.k.a. hydrogen ions or H+) are small enough to passively go right through a membrane, otherwise mitochondria would have to work too hard to regenerate ATP! True or False?arrow_forwardThe electron transport chain makes no ATP directly. Instead, it eases the fall of electrons from food to oxygen, breaking a large free-energy drop into a series of smaller steps that release energy in manageable amounts, step by step. How does the mitochondrion (or the plasma membrane in prokaryotes) couple this electron transport and energy release to ATP synthesis?arrow_forwardIn aerobic cellular respiration, which reactions occur only in the cytoplasm? Which ones occur only in a cells mitochondria?arrow_forward
