During aerobic respiration, one molecule of glucose is oxidized to two molecules of pyruvate in the cytosol. Continuing from this point, describe the process that occurs whereby the pyruvate ultimately continues to be oxidized down to CO2 that exits the cell. Use structures and include the total numbers of the final end products of this process.
Homework Answers
The pyruvate then enters to the mitochondria. The pyruvate is then oxidized into acetyl CoA. The acetyl CoA then enters to TCA cycle. In TCA cycle GTP, NADH, CO2 are produced. The entire process is occurred in mitochondrial matrix.

During EMP glycolysis, 1 molecule of glucose is broken down into two molecules of pyruvate and 2 molecules of NADH are produced. During fermentation, 1 molecule of pyruvate is reduced. During this process, one molecule of NADH is oxidized. If 34 molecules of glucose are broken down during glycolysis, and all the resultant molecules of pyruvate are reduced by fermentation, how many molecules of NADH will remain?
