During light reactions in photosynthesis, light energy is absorbed by chlorophyll in the thylakoid membranes of chloroplasts. This energy is used to split water into oxygen, protons, and electrons. The electrons are then passed through a series of proteins in the electron transport chain, generating ATP and NADPH, which are used in the Calvin cycle to produce sugars.
What else can I help you with?
Oxygen is produced during the light reactions when?
Oxygen is produced during the light reactions of photosynthesis when water molecules are split by the photosystem II complex. This process releases oxygen as a byproduct.
What is the term for reaction that release energy?
Exothremic Reactions
Is oxygen made during the Calvin cycle?
No, oxygen is not made during the Calvin cycle. The Calvin cycle is part of the light-independent reactions in photosynthesis and is responsible for converting carbon dioxide into glucose, not producing oxygen. Oxygen is produced during the light-dependent reactions of photosynthesis.
Where does splitting of water and oxygen happen?
The splitting of water and oxygen happens in the chloroplasts of plant cells during the light-dependent reactions of photosynthesis. This process, known as photolysis, is catalyzed by the enzyme complex photosystem II.
Which one of these occurs during the light reactions of photosynthesis a- carbon dioxide fixation b-g3p production c- nadph production d- reduction of carbon dioxide?
c- NADPH production occurs during the light reactions of photosynthesis.
What happens during each 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.

What is produced during the light dependent reactions and used during the light independent reactions of?
ATP and NADPH
What is produced during the light dependent reactions of used during the light independent reactions of photosynthesis?
ATP and NADPH
What is produced during the light dependent reactions and used during the light independent reactions of potosynthesis?
ATP and NADPH
What occurs during the light reactions?
During light dependent reactions chlorophyll and other light-aborbing molecules capture energy from sunlight.
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 is produced during the light dependent reactions and used the light independent reactions of photosynthesis?
ATP and NADPH
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 is produced during the lights dependent reactions and used during the light independent reactions of photosynthesis?
ATP and NADPH
Phase of photosynthesis where light energy is converted to chemical in form of ATP?
The phase of photosynthesis where light energy is converted to chemical energy in the form of ATP is called the light-dependent reactions. During these reactions, light is absorbed by chlorophyll and other pigments in the thylakoid membranes of the chloroplast, leading to the generation of ATP and reducing power (NADPH) that will be used in the Calvin cycle to produce sugars.
What happens the light dependant reactions?
The light dependent reactions produce Oxygen Gas and convert ADP and NADP+ into the energy carriers ATP and NADPH.
