Question

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?
light energy, above the arrow
chlorophyll, to the left of the arrow
enzymes, to the left of the arrow
atp, above the arrow

Explanation:

Photosynthesis is a process that uses light energy. The general chemical equation for photosynthesis is \(6CO_2 + 6H_2O
ightarrow C_6H_{12}O_6+6O_2\). This reaction occurs in the presence of light energy (captured by chlorophyll). Chlorophyll is a pigment in the chloroplasts of plant cells that absorbs light energy, but it is not a reactant (so it should not be on the left - hand side of the arrow). Enzymes are biological catalysts that speed up the reaction but are not reactants. ATP is produced during photosynthesis (not used as an input above the arrow in the overall equation). Light energy is required for the reaction to occur and is typically shown above the arrow in the chemical equation of photosynthesis.

Answer:

light energy, above the arrow
