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? glycolysis citric acid cycle ATP synthase electron transport chain R

The correct answer is Citric Acid Cycle or Krebs Cycle.

Explanation:

The citric acid requires Acetyl CoA as a substrate for the production of a series of chemicals that will lead to obtaining NADH, FADH2, and ATP. These molecules are energy, and they will then start the electron transport chain in the oxidative phosphorylation. Therefore, if there's no Acetyl CoA the citric acid cannot begin and the whole cycle will be interrupted.
