Arsenic is a poison that binds to a molecule needed to build acetyl CoA. Based on this information, which part of cellular respiration would be stopped if arsenic were ingested?

Question

Quizplus · Accepted Answer

The citric acid cycle is responsible for producing acetyl CoA, which is required for the later stages of cellular respiration. Arsenic binds to the molecule needed to build acetyl CoA, so the citric acid cycle would be stopped if arsenic were ingested. Glycolysis, electron transport chain, and ATP synthase are not directly affected by arsenic's mechanism of action.
