Question
The process of photosynthesis can be represented by the chemical formula
Responses
A C6H12O6 + 6O2 → 6CO2 + 6H2O + energyC 6 H 12 O 6 + 6O 2 → 6CO 2 + 6H 2 O + energy
B C6H12O6 + 6H20 → 6CO2 + 6H2OC6H12O6 + 6H20 → 6CO2 + 6H2O
C 6CO2 +6H2O → C6H12O6 + 6O26CO 2 +6H 2 O → C 6 H 12 O 6 + 6O 2
D 6CO2 + H2O → C6H12O6 + 6O2
C 6CO2 +6H2O → C6H12O6 + 6O26CO 2 +6H 2 O → C 6 H 12 O 6 + 6O 2
The correct response is:
A) C6H12O6 + 6O2 → 6CO2 + 6H2O + energy
To determine the correct answer, we need to understand the process of photosynthesis and the chemical equation that represents it.
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to produce glucose (C6H12O6) and oxygen (O2). This process occurs in the chloroplasts of plant cells.
The chemical equation for photosynthesis is:
6CO2 + 6H2O → C6H12O6 + 6O2
This equation shows that six molecules of carbon dioxide (CO2) and six molecules of water (H2O) react in the presence of sunlight to produce one molecule of glucose (C6H12O6) and six molecules of oxygen (O2).
Now, let's analyze the given options:
A) C6H12O6 + 6O2 → 6CO2 + 6H2O + energy
This equation represents the reverse process of photosynthesis, which is cellular respiration. It is incorrect for photosynthesis.
B) C6H12O6 + 6H20 → 6CO2 + 6H2O
This equation is incorrect because it is missing the production of oxygen (O2) and does not balance the number of oxygen and hydrogen atoms.
C) 6CO2 + 6H2O → C6H12O6 + 6O2
This equation is the correct representation of photosynthesis. It accurately describes the reactants (carbon dioxide and water) and the products (glucose and oxygen), as well as the balanced number of atoms.
D) 6CO2 + H2O → C6H12O6 + 6O2
This equation is incorrect because it does not balance the number of hydrogen and oxygen atoms.
Therefore, the correct answer is option C:
C) 6CO2 + 6H2O → C6H12O6 + 6O2
