Products of photosynthesis are the reactants of cellular respiration.
Reactants of cellular respiration are the reactants of photosynthesis.
Products of cellular respiration and photosynthesis is glucose and water.
None of the above descriptions accurately describes the relationship between photosynthesis and cellular respiration. The correct description is:
Photosynthesis and cellular respiration are complementary processes that occur in living organisms. During photosynthesis, plants and some other organisms convert sunlight, carbon dioxide, and water into glucose and oxygen. The glucose produced is then used as a source of energy during cellular respiration. In cellular respiration, glucose and oxygen are metabolized to produce carbon dioxide, water, and ATP (adenosine triphosphate), which is the cell's main energy currency. Therefore, the products of photosynthesis (glucose and oxygen) are the reactants of cellular respiration, and the products of cellular respiration (carbon dioxide, water, and ATP) are the reactants of photosynthesis.
The correct description of the relationship between photosynthesis and cellular respiration is that the products of photosynthesis, which are glucose and oxygen, are the reactants or inputs for cellular respiration. In turn, the products of cellular respiration, which are carbon dioxide, water, and ATP (adenosine triphosphate), are the reactants or inputs for photosynthesis. This creates a cyclic relationship between these two processes.
To determine the correct description of the relationship between photosynthesis and cellular respiration, we need to understand both processes.
1. Photosynthesis: This is the process by which plants, algae, and some bacteria convert sunlight, carbon dioxide, and water into glucose and oxygen. In photosynthesis, sunlight energy is converted into chemical energy stored in glucose. The equation for photosynthesis is as follows:
6CO2 + 6H2O + sunlight energy → C6H12O6 + 6O2
2. Cellular Respiration: This is the process by which cells break down glucose and release energy that can be used for cellular activities. In cellular respiration, glucose and oxygen are used to produce carbon dioxide, water, and energy (in the form of ATP, adenosine triphosphate). The equation for cellular respiration is as follows:
C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP (energy)
Now, let's analyze the given options:
A. Products of photosynthesis are the reactants of cellular respiration:
This statement is correct. The products of photosynthesis (glucose and oxygen) are used as the reactants in cellular respiration.
B. Reactants of cellular respiration are the reactants of photosynthesis:
This statement is incorrect. The reactants of cellular respiration (glucose and oxygen) are not the same as the reactants of photosynthesis (carbon dioxide and water).
C. Products of cellular respiration and photosynthesis are glucose and water:
This statement is partially correct. The products of photosynthesis include glucose, but the products of cellular respiration are carbon dioxide and water.
Therefore, the correct description of the relationship between photosynthesis and cellular respiration is that the products of photosynthesis (glucose and oxygen) are the reactants of cellular respiration.
