The Light-Dependent Reactions – Principles of Biology

WebThere are two types of light reactions: Cyclic Non-cyclic The cyclic reaction is called so because the electron is emitted from photosystem I, passes onto electron acceptor molecules and finally returns to photosystem I. Cyclic reaction is the same as the non-cyclic process. Here too ATP is created but no NADPH. WebThe light reactions of photosynthesis occur in the thylakoid membranes of the chloroplast. Electron carrier molecules are arranged in electron transport chains that produce ATP and NADPH, which temporarily store chemical energy. rainfall statistics ketchikan alaska
