Write out the three factors that affect photosynthesis.
write out the formula of photosynthesis in both words and symbols.
Reorder the process of ATP synthesis.
electrons from water molecules flow to the photosystem II.
PSII absorbs light and changes the low energy electrons into high energy electrons.
High energy electrons go through the electrons transport chain.
The electron transport chain uses energy lost by the high energy electrons to pump the H+ ions into the thylakoid space
The H+ ions escape through the ATP synthase. 1. The ATP synthase rotates as the H pass through. When the ATP rotates, ADP converts to ATP.
Reorder the process of NADPH synthesis.
The high energy electrons lost energy to the electron transport chain and become low energy electrons.
The low energy electrons get energy in photosystem I and become high-energy electrons again.
The high energy electrons combine with the NADP+ and become NADPH.
