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. Light energy is the key factor that drives the reaction and is written above the arrow in the chemical - equation to show it is required for the process to occur. Chlorophyll is a pigment that absorbs light energy and is part of the plant structure, not a reactant written in the main equation in the same way. Enzymes are catalysts and not the main components of the photosynthesis equation in this context. ATP is a product of some steps in photosynthesis and not something added above the arrow to represent the overall process.

Answer:

light energy, above the arrow
