Thylakoid Membrane
Light Reactions
Light-Dependent Reactions: Uses H₂O + light energy → O₂ + ATP + NADPH. Drag 2 water molecules here when light is active!
Calvin Cycle
ATP: 0
NADPH: 0
Calvin Cycle: Uses 3 CO₂ + 3 ATP + 2 NADPH → 1 G3P. This is where carbon fixation happens to build sugar precursors!
Glucose Synthesis
G3P: 0
Glucose Synthesis: Combines 2 G3P → 1 Glucose. The final step where sugar is assembled for energy storage!

🌻 Welcome to the Sugar Factory! 🌻

Your Mission:

Help the plant create glucose by completing the two stages of photosynthesis.

1
Add water (H₂O) and activate sunlight to power the light reactions in the thylakoid
2
Drag molecules into their matching slots - they'll snap into place!
3
Click reaction zones when all slots are filled to trigger reactions
4
Use CO₂ with ATP & NADPH in the Calvin Cycle to make G3P
5
Combine 2 G3P molecules to create glucose - your sugar goal!

Answer quiz questions after each reaction to test your knowledge!
