Which of the following is NOT a reactant in the process of cellular respiration?
A
Oxygen ($O_2$)
B
Glucose ($C_6H_{12}O_6$)
C
Water ($H_2O$)
D
Carbon dioxide ($CO_2$)
Verified step by step guidance1
Step 1: Begin by understanding the process of cellular respiration. Cellular respiration is a metabolic pathway that converts glucose ($C_6H_{12}O_6$) and oxygen ($O_2$) into energy in the form of ATP, with carbon dioxide ($CO_2$) and water ($H_2O$) as byproducts.
Step 2: Identify the reactants in cellular respiration. Reactants are substances that are consumed during the reaction. In cellular respiration, the primary reactants are glucose ($C_6H_{12}O_6$) and oxygen ($O_2$).
Step 3: Recognize the products of cellular respiration. The products are substances formed as a result of the reaction. Cellular respiration produces carbon dioxide ($CO_2$), water ($H_2O$), and ATP.
Step 4: Analyze the options provided in the question. Oxygen ($O_2$) and glucose ($C_6H_{12}O_6$) are reactants, while water ($H_2O$) is a product. Carbon dioxide ($CO_2$) is also a product, not a reactant.
Step 5: Conclude that the correct answer is carbon dioxide ($CO_2$), as it is not a reactant in the process of cellular respiration but rather a product.
