Which of the following is true?
A. The products of photosynthesis are the reactants of cellular respiration.
B. The products of cellular respiration are the reactants of glycolysis.
C. The products of cellular respiration are the reactants of photosynthesis.
D. A and C are true.
Answer (2)
The statement that is true is D. a and c are true: the products of photosynthesis are the reactants of cellular respiration, and the products of cellular respiration are the reactants of photosynthesis.
Comparing the processes of photosynthesis and cellular respiration reveals how they are connected and integral to life on Earth. Photosynthesis converts light energy into chemical energy stored in glucose (C6H12O6), utilizing carbon dioxide (CO2) and water (H2O) as reactants in the presence of sunlight and chlorophyll. Cellular respiration, on the other hand, releases energy from glucose to synthesize ATP, using oxygen (O2) as one of the reactants. Thus, statement A, "The products of photosynthesis are the reactants of cellular respiration," is true. Additionally, statement C is also true as the products of cellular respiration, carbon dioxide, and water, are the reactants for photosynthesis, forming a cycle and connecting producers to consumers within ecosystems.
Therefore, the correct answer to the student's question is D. a and c are true. Photosynthesis uses water and carbon dioxide to produce glucose and oxygen, which are then used by cellular respiration to produce ATP, water, and carbon dioxide. This demonstrates the interdependence between the two processes and forms the basis of the carbon-oxygen cycle.
The correct answer is D. A and C are true. This is because the products of photosynthesis (glucose and oxygen) are the reactants for cellular respiration, and the products of cellular respiration (carbon dioxide and water) are the reactants for photosynthesis. This cycle highlights the interconnectedness of these two processes essential for life.
