Question

What is needed in photosynthesis to convert carbon dioxide into organic molecules?

• A. Light and hydrogen from the splitting of water
• B. Light and oxygen from the splitting of water
• C. ATP and hydrogen from the splitting of water
• D. ATP and oxygen from the splitting of water

Answer 1

Answer: (A)

Light and hydrogen from the splitting of water

The process of photosynthesis in plants involves a series of steps and reactions that use light energy, water, and carbon dioxide to produce oxygen and organic compounds.

6CO${}_2$ + 6H${}_2$O + light energy $⟶$ C${}_6$H${}_{12}$O${}_6$ + 6O${}_2$.

Here, glucose is produced using the Hydrogen, emitted from the splitting of water. Light energy is also required for the reaction to take place.
