Question

complete this assessment to review what youve learned. it will not count toward your grade. which compound is a reactant of both cellular respiration and dehydration synthesis? (1 point) oxygen glucose water atp

Explanation:

1. Recall the reactants of cellular respiration: The overall equation of cellular respiration is \( C_6H_{12}O_6 + 6O_2

ightarrow6CO_2 + 6H_2O+ ATP\), so glucose (\(C_6H_{12}O_6\)) and oxygen are reactants.

1. Recall the process of dehydration synthesis: Dehydration synthesis is a process where monomers are joined to form polymers, and water is removed. For example, when monosaccharides (like glucose) are joined to form polysaccharides, glucose is a reactant, and water is a product.
2. Analyze each option:

• Oxygen: It is a reactant in cellular respiration but not in dehydration synthesis (dehydration synthesis does not require oxygen as a reactant).
• Glucose: It is a reactant in cellular respiration (used to produce ATP) and in dehydration synthesis (used to build larger carbohydrate molecules like starch or glycogen by joining with other glucose molecules, with water being removed).
• Water: In cellular respiration, water is a product (in aerobic respiration), and in dehydration synthesis, water is a product (not a reactant).
• ATP: ATP is a product of cellular respiration, not a reactant. And it is not a typical reactant in dehydration synthesis.

Answer:

B. glucose
