Navah writes out the chemical equation for photosynthesis. she includes two reacting molecules to the left of the arrow and two resulting molecules to the right. what must be added to the chemical equation to more accurately represent photosynthesis?
a) light energy,
b) above the arrow chlorophyll,
c) to the left of the arrow enzymes,
d) to the left of the arrow atp,
e) above the arrow

The correct answer is A) light energy

Explanation:

Photosynthesis is the process through which plants make their food in the form of glucose with the help of carbon dioxide and water in the presence of sunlight. Six molecules of oxygen are released in this process.

Photon present in the sunlight provides energy which is absorbed by a green pigment chlorophyll present in the thylakoid of chloroplast. Then this energy is used for carbon fixation process to obtain glucose.

The reaction of photosynthesis is:

        6CO₂ + 6H₂O + Sunlight → C₆H₁₂O₆ + 6O₂

Therefore sunlight must be added to the chemical equation to more accurately represent photosynthesis.
