Arsenic poisoning can inhibit several enzymes, including lipoic acid-containing enzymes like pyruvate dehydrogenase. How would arsenic poisoning indirectly affect glycolysis?
Arsenic directly inhibits hexokinase, the first enzyme in glycolysis.
Arsenic enhances glycolysis by stimulating phosphofructokinase activity.
By inhibiting pyruvate dehydrogenase, arsenic poisoning would lead to a buildup of pyruvate, which could in turn inhibit glycolysis through feedback mechanisms.
Arsenic has no effect on glycolysis as it specifically targets mitochondrial enzymes.
