Understand the process of photosynthesis: Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy stored in glucose. The general equation for photosynthesis is: 6CO2 + 6H2O + light energy → C6H12O6 + 6O2.
Identify the products of photosynthesis: From the equation, the products of photosynthesis are glucose (C6H12O6) and oxygen (O2).
Understand the process of cellular respiration: Cellular respiration is a set of metabolic reactions used by cells to convert biochemical energy from nutrients into ATP, and then release waste products. The general equation for cellular respiration is: C6H12O6 + 6O2 → 6CO2 + 6H2O + energy (ATP).
Identify the reactants of cellular respiration: From the equation, the reactants of cellular respiration are glucose (C6H12O6) and oxygen (O2).
Determine the compound that is both a product of photosynthesis and a reactant in cellular respiration: By comparing the products of photosynthesis and the reactants of cellular respiration, glucose (C6H12O6) is the compound that fits both criteria.
