This deep dive covers Uses of Glucose within Photosynthesis for GCSE Biology. Topic 1: Photosynthesis It is section 5 of 14 in this topic. Use this deep dive to connect the idea to the wider topic before moving on to questions and flashcards.
🍬 Uses of Glucose
Plants use the glucose produced during photosynthesis for five key purposes:
- Respiration — glucose is broken down to release energy for life processes.
- Starch — excess glucose is converted to insoluble starch for storage.
- Cellulose — glucose is used to build cell walls.
- Lipids — glucose is converted into fats and oils for energy storage in seeds.
- Proteins — glucose combines with nitrate ions (from soil) to make amino acids and proteins.

Quick recall flashcards
What is the role of chlorophyll?
Chlorophyll absorbs light energy to power photosynthesis.
It is green because it reflects green light and absorbs red and blue.
Word equation for photosynthesis?
carbon dioxide + water → glucose + oxygen
(requires light energy)
