During the light-dependent reactions of photosynthesis, water is split in the thylakoid membranes of chloroplasts. This process occurs in a complex known as Photosystem II, where water is photolyzed into oxygen, protons, and electrons. The released oxygen is expelled as a byproduct, while the electrons are used to drive the electron transport chain and generate energy-rich molecules like ATP and NADPH.

What by-products are formed during photosynthesis?

During photosynthesis, by-products like oxygen and water are formed. Oxygen is released into the atmosphere as a waste product of the light-dependent reactions, while water is produced as a result of the splitting of water molecules in the light-dependent reactions.

The initial reactions in photosynthesis are know as the?

The initial reactions in photosynthesis are known as the light-dependent reactions. These reactions occur in the thylakoid membranes of the chloroplast and involve the absorption of light energy to drive the conversion of water into oxygen, ATP, and NADPH.


What are the byproducts of the Light Dependent Reactions?

The byproducts of the Light Dependent Reactions of photosynthesis are oxygen, ATP, and NADPH. During these reactions, water molecules are split, releasing oxygen as a byproduct. Meanwhile, the energy captured from sunlight is used to convert ADP and NADP+ into the energy carriers ATP and NADPH, which are then utilized in the subsequent Light Independent Reactions (Calvin Cycle).
