Photosynthesis: An Overview

• Photosynthesis is a series of chemical reactions that occurs in producers such as plants and algae

• Photosynthesis converts light energy into chemical energy which is then stored in the biomass of producers

• The light energy is used to split strong bonds in water molecules (H₂O), releasing hydrogen and oxygen

• Oxygen is released into the atmosphere as a waste product

• Hydrogen is combined with carbon dioxide to produce glucose 

  • Chemical energy is stored within the bonds in glucose molecules; glucose can therefore function as a fuel for respiration

  • It can be said that hydrogen is stored in glucose molecules

Photosynthesis requires energy from light to split water molecules. The resulting hydrogen combines with carbon dioxide and is stored in glucose, which fuels respiration. Oxygen is released as a waste product.
