Glycolysis is the first step of cellular respiration, in which glucose is used to generate ATP to power the cell. The major chemical reaction that takes place in glycolysis (ignoring some other reactants and products) is the conversion of glucose
(C6H12O6 ) to pyruvate (C3H4O3 ) and hydrogen ions (H+). Using this information, what is the correct equation for the glycolysis chemical reaction? A) C6H12O6 ? C3H4O3 + H+ B) C6H12O6 ? 2 C3H4O3 + 2 H+ C) C6H12O6 ? 2 C3H4O3 + H+ D) 2 C6H12O6 ? C3H4O3 + 2 H+
