Practice questions testing deep understanding of glycolysis, Krebs cycle, and the ETC.
Q1. Cyanide is a highly lethal poison that kills humans and plants within minutes. It works by irreversibly binding to Cytochrome c oxidase, the final complex in the Electron Transport Chain (ETC) located in the mitochondria. Explain the biochemical domino effect of how stopping this one enzyme causes the death of the cell.
Q2. Glycolysis is considered the universal first step of respiration, occurring in every living organism from bacteria to humans. State where exactly in the cell it occurs, and explain why it can take place in completely anaerobic (oxygen-free) environments.
Q3. Assertion (A): The Krebs Cycle (Citric Acid Cycle) can only operate if oxygen is present in the cell. Reason (R): Oxygen directly reacts with acetyl-CoA in the first step of the Krebs cycle to produce citric acid.
