Step 1. Light is absorbed by leaf cells and it excites chlorophyll a, chlorophyll b
Step 2. That highly charged electron will pass through PEA molecules in the thylakoid membrane
Step 3. The electron energy moves through the ETC proteins along the thylakoid membranes in light reaction.
Step 4. Water splitting occurs in Calvin cycle in Light reactions. oxygen is released into air.
Step 5. The less energetic electrons that moved down the ETC will now react with hydrogen ion in stroma to form the Hydrogen atom
Step 6. The Hydrogen ion within thylakoid will create a higher concentration gradient than that present in the stroma. Unused energy stored in stroma.
Step 7. A carbon dioxide molecule is added to the 5C atom in carbon cycle
Step 8. Three carbon compounds are formed ultimately in Calvin cycle and are eventually transported to other parts of the plant.
