Select the correct response regarding the relationship between photosynthesis and cellular respiration.
a
the reactants and products of photosynthesis has no relationship with the reactants and products of cellular respiration.
b
the products of cellular respiration are the reactants of photosynthesis.
c
the reactants of photosynthesis are the reactants of cellular respiration.
d
the products of cellular respiration are the products of photosynthesis.
b
the products of cellular respiration are the reactants of photosynthesis.
b) The products of cellular respiration are the reactants of photosynthesis.
To determine the correct response regarding the relationship between photosynthesis and cellular respiration, we need to understand the processes of both.
Photosynthesis is a process that occurs in plants, algae, and some bacteria. It involves the conversion of light energy into chemical energy, which is stored in the form of glucose (a sugar molecule). The reactants for photosynthesis are carbon dioxide (CO2) and water (H2O), and the products are glucose and oxygen (O2).
On the other hand, cellular respiration is a process that occurs in all living cells, including plants, animals, and humans. It involves the breakdown of glucose to release chemical energy, which is then used to power the various activities of the cell. The reactants for cellular respiration are glucose and oxygen (O2), and the products are carbon dioxide (CO2), water (H2O), and ATP (adenosine triphosphate).
With this understanding, we can evaluate the given options:
a) The statement that the reactants and products of photosynthesis have no relationship with the reactants and products of cellular respiration is incorrect. Photosynthesis produces glucose and oxygen, which are the reactants of cellular respiration.
b) The statement that the products of cellular respiration are the reactants of photosynthesis is correct. The oxygen produced during photosynthesis is utilized as a reactant in cellular respiration.
c) The statement that the reactants of photosynthesis are the reactants of cellular respiration is incorrect. While both processes require oxygen as a reactant, the other reactants differ (CO2 and H2O for photosynthesis and glucose and O2 for cellular respiration).
d) The statement that the products of cellular respiration are the products of photosynthesis is incorrect. While carbon dioxide and water are produced as byproducts in photosynthesis, they are not the main products.
Therefore, the correct response is option b: the products of cellular respiration are the reactants of photosynthesis.
