What is a light-dependent reaction in photosynthesis?
Q: What is a light-dependent reaction in photosynthesis?
A: A light-dependent reaction in photosynthesis is the process that uses light energy from the sun to split water which has been taken in by the organism.
Q: What are the products of splitting water during a light-dependent reaction?
A: The products of splitting water during a light-dependent reaction are oxygen, hydrogen, and electrons.
Q: What chemical process results in the production of ATP during a light-dependent reaction?
A: The chemical process that results in the production of ATP during a light-dependent reaction is chemiosmosis.
Q: Where do the electrons move through structures during a light-dependent reaction in photosynthesis?
A: The electrons move through structures in chloroplasts during a light-dependent reaction in photosynthesis.
Q: What is NADPH and what is its role during a light-dependent reaction in photosynthesis?
A: NADPH is a molecule that is formed during a light-dependent reaction in photosynthesis by converting hydrogen. Its role is to be used in the light-independent reactions.
Q: What happens to oxygen gas during a light-dependent reaction in photosynthesis?
A: Oxygen gas diffuses out of the organism as a waste product during a light-dependent reaction in photosynthesis.
Q: Where does a light-dependent reaction occur in chloroplasts?
A: A light-dependent reaction occurs in the grana thylakoid of chloroplasts.
