light strikes photosystem 2, exciting the electrons. The electron come from a water molecule that has been split into hydrogen and oxygen. That is the first reactant (water), and Oxygen gas is given off as the first product. The excited electrons then travel down a short electron transport chain, and while doing so they pump H+ molecules (hydrogen molecules) into the inner thylakoid space across the thylakoid membrane from the stroma. The electrons are then passed, at the end of the transport chain, to photosystem 1, where they are re-excited by light. The electrons are passed down another short electron transport chain, which pumps a few more H+ into the thylakoid space, then the electrons get passed to a molecule of NADP+, which is reduced to NADPH. NADPH is a product, NADP+ a reactant. The H+ in the thylakoid then diffuse back into the stroma through a molecule of ATP Synthase that is a channel through the memebrane of the thylakoid. As they pass through the ATP synthase, the H+ make the ATP Synthase go into it's active conformation so it is able to turn ADP into ATP. ADP is a reactant, ATP is a product. To sum it all up, H20, NADP+, and ADP are reactants, and oxygen, NADPH, and ATP are products
What else can I help you with?
Photosynthesis generates ATP and NADPH during what stages?
Photosynthesis generates ATP during the light-dependent reactions (photophosphorylation) and NADPH during the light-dependent reactions (photolysis of water and reduction of NADP+ to NADPH).
What molecule is split during the light reactions of photosynthesis to release oxygen?
Water molecule is split during the light reactions of photosynthesis to release oxygen.
What two types of reactions occur during photosynthesis?
The two reactions which occur during photosynthesis are light reaction and dark reaction. Light reaction takes place only in the presence of light. Dark reaction can occur with or without light.
What happens during each of the two stages of photosynthesis?
These stages are called the light reactions and the dark reactions. The light reactions take place in the presence of of light. The dark reactions do not require direct light, however dark reactions in most plants occur during the day.
Is it the light absorbed or light reflected that initiates the light reactions of photosynthesis?
The light absorbed by chlorophyll initiates the light reactions of photosynthesis. Chlorophyll molecules in the thylakoid membranes of chloroplasts absorb light energy and convert it into chemical energy, which is used to drive the conversion of water and carbon dioxide into oxygen and carbohydrates during photosynthesis.

ATP and NADPH
