In this situation, muscle cells ferment glucose to two molecules of lactic acid — again, with the net production of only two molecules of ATP per glucose molecule (Figure 16-6, left).
As we break down the glucose via glycolsis and then Kreb cycle , the carbons releases from of our body in the gaseous form called CO2 !!
38 ATP is formed as a result !! And in waste CO2 is formed !!
Energy comes from making bonds in carbon dioxide and water.
