Question

the reactants for cellular respiration are... oxygen and water; oxygen and glucose; water and carbon dioxide; glucose and carbon dioxide

Explanation:

Cellular respiration is the process by which cells break down glucose to release energy, and oxygen is required for aerobic respiration. The chemical equation for cellular respiration is \( C_6H_{12}O_6 + 6O_2
ightarrow 6CO_2 + 6H_2O + \text{Energy} \). So the reactants (substances that start the reaction) are glucose (\( C_6H_{12}O_6 \)) and oxygen (\( O_2 \)).

Answer:

B. Oxygen and Glucose (assuming the blue option is labeled as B, if the options are labeled as A: Oxygen and Water, B: Oxygen and Glucose, C: Water and Carbon Dioxide, D: Glucose and Carbon Dioxide)
