Thinking about the number of carbon atoms in glucose and in pyruvic acid, explain why there
is one molecule of glucose on the left side of the arrow and two molecules of pyruvic acid on
the right side of the arrow. - CORRECT ANSWER✔✔- There is only 3 carbon in pyruvic
acid, so since glucose had 6 carbon, it split into 2 pyruvics making 6 altogether.
