The combustion of sugar is a reaction between sugar and oxygen that results in carbon dioxide and water. A combustion reaction requires a large energy input to begin. How does the cell overcome the need for large energy input to begin the reaction of glucose and oxygen during cellular respiration? Choose the correct answer. A: Enzymes lower the amount of energy necessary to begin the reaction of glucose and oxygen.
B: Enzymes physically break apart and recombine the glucose and oxygen molecules so no energy is needed for the reaction.
C: The cell creates new energy to begin the reaction between glucose and oxygen.
D: The cell uses energy from sunlight to begin the reaction between glucose and oxygen.
