The mechanism by which pyruvate from cytosol is transpoed to mitochondria is?: (A) Chloride antipo, (B) Proton sympo, (C) ATP dependent antipo, (D) Facilitated unipo
Answer is B. The transpo of pyruvate into the mitochondria is the transpo protein pyruvate translocase. Pyruvate translocase transpos pyruvate in a sympo fashion with a proton, and hence is active, consuming energy.Ref: DM Vasudevan, 7th edition
