In the light-dependent reactions, electrons are removed from water molecules to replace those lost by a specific reaction center. To which center are these electrons first transferred?
Q1. In the light-dependent reactions, electrons are removed from water molecules to replace those lost by a specific reaction center. To which center are these electrons first transferred?
Answer: P680
Explanation: P680 (PS II) is the first to receive electrons from the photolysis of water, while P700 belongs to Photosystem I.
