Drugs containing cyanide inhibit cytochrome c oxidase, the last enzyme in the mitochondrial electron transport chain. What is the effect of cyanide poisoning on cellular respiration? All ATP production by the cell will stop. All NADH in the mitochondria will become oxidized to NAD+. Fermentation cannot occur, so lactic acid cannot be made. Glucose cannot be oxidized to make pyruvate. Oxygen cannot be reduced to make water.

Step 1
This means that the electron transport chain cannot function properly, leading to a disruption in the process of oxidative phosphorylation. As a result, the production of ATP through oxidative phosphorylation will be significantly reduced or stopped. This is Show more…

Complete the following statement. Mark all that apply. Cyanide is a metabolic poison that inhibits the cytochrome c oxidase complex. Therefore, when exposed to cyanide, cells lose the ability to... transfer energy from NADH to ATP. reduce cytochrome c oxidase. pump ATP across the inner mitochondrial membrane. produce carbon dioxide in the Krebs cycle pump ATP across the outer mitochondrial membrane. complete the oxidation reactions of glycolysis. oxidize cytochrome c oxidase. produce ATP. pump hydrogen ions across the outer mitochondrial membrane. pump hydrogen ions across the inner mitochondrial membrane. consume oxygen to oxidize glucose.
