Question

The chemical formula for glucose sugar is C₆H₁₂O₆. When a glucose molecule is made during photosynthesis, what process adds 12 hydrogen ions to the CO₂ carbon dioxide to make the glucose sugar?

Answer 1

The process that adds 12 hydrogen ions (H+) to CO₂ during photosynthesis to make glucose sugar is the reduction reaction.

Step-by-step explanation:

During photosynthesis, the process that adds 12 hydrogen ions (H+) to carbon dioxide (CO₂) to make glucose sugar is called the reduction reaction. The reduction reaction occurs in the stroma of the chloroplasts, where the energy from sunlight is used to convert CO₂ and water (H₂O) into glucose and oxygen (O₂). The hydrogen ions come from the splitting of water molecules during the light reactions of photosynthesis.
