B sugarsugar
C waterwater
D carbon dioxide
B sugarsugar
The substance that is a reactant, along with oxygen, in cellular respiration is B) sugar(sugar).
To determine which substance is a reactant, along with oxygen, in cellular respiration, we need to understand the process of cellular respiration. Cellular respiration is the process by which cells convert oxygen and glucose (a type of sugar) into carbon dioxide, water, and energy in the form of ATP (adenosine triphosphate).
Thus, the correct answer is B - sugars (sugar).
Therefore, sugar (glucose) is the substance that acts as a reactant, along with oxygen, in cellular respiration.
