Answer:c) glucose
Explanation: The complete balanced chemical equation is C6H12O6 + 6O2 --> 6CO2 + 6H2O + Energy.
The equation above represents cellular respiration. During respiration, one molecule of glucose (C6H12O6) is broken down in the presence of six molecules of oxygen (O2) to produce six molecules of carbon dioxide (6CO2), six molecules of water (6H2O) and energy (ATP).
Im not positive, but i believe that the heat on the burner would allow her to control the rate of reaction!
