Question

Photolysis of water occurs in photosynthesis. Describe what happens during photolysis. (2)

a) Photolysis is the breakdown of glucose into carbon dioxide and water.
b) Photolysis is the process of splitting water molecules into oxygen and hydrogen using light energy.
c) Photolysis involves the conversion of water into carbohydrates.
d) Photolysis releases carbon dioxide and water as products.

Answer 1

Photolysis in photosynthesis is the process of splitting water molecules into oxygen and hydrogen using light energy.

Step-by-step explanation:

During photolysis in photosynthesis, water molecules are split into oxygen and hydrogen using light energy. This process occurs in the light-dependent reactions of photosynthesis and takes place in the thylakoid membranes of the chloroplasts. The oxygen produced is released as a byproduct, while the hydrogen ions and high-energy electrons continue to participate in further reactions in the overall photosynthesis process.
