If you answer this correctly and show your thinking, I will mark you as brainliest!! Use the Pyruvate Concentration Table to answer the question.

Shortly before the four-hour mark, the researcher inhibits the activity of proton pumps in the outer mitochondrial membrane. Which of the following conclusions do the data support?
A. The protein channel in the outer mitochondrial membrane is activated by membrane potential.
B. The glucose carrier protein in the plasma membrane is activated by membrane potential.
C. The pyruvate carrier protein in the mitochondrial outer membrane is a cotransporter.
D. The cell uses cotransporters to transport pyruvate from the mitochondria to the cytosol.
