The mechanism by which cytosol pyruvate is transported to mitochondria is: (A) Chloride antiport, (B) Proton symport, (C) ATP dependent antiport, (D) Facilitated uniport
Answer is B. Pyruvate is formed from glucose oxidation (glycolysis) in cytosol.
It is transported into the mitochondria along with Er (proton) symport by a monocarboxylate carrier.
