Answer:
High energy electrons are highly reactive
Step-by-step explanation:
Chloroplast is a cellular organelle responsible for photosynthesis. It consists of a well-organized system of membranes called thylakoids that invaginate to form saccules. It is also in the thylakoid membrane that the molecules responsible for electron transport are found: electron transport chain. This chain is important because the high-energy electrons (used in photosynthesis) are very reactive and can react with the wrong molecules outside the chain.
