In what part of the chloroplasts do light phase reactions occur? What are the main reactions caused by light. Write their equations.

This phase occurs only in the presence of light in the membranes of thylakoids with the participation of chlorophyll, electron carrier proteins and the enzyme ATP synthetase. Under the influence of a quantum of light, chlorophyll electrons are excited, leave the molecule and fall on the outside of the thylakoid membrane, which ultimately charges negatively. Oxidized chlorophyll molecules are restored by taking away electrons from water in the intrathylakoid space. This leads to the decay or photolysis of water; Н2О + Qlight -> Н + + ОН-.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
