Where did the energy to power the light-independent reactions come from? (1 point) Responses chlorophyll from photosystem chlorophyll from photosystem FADH2 from the outer membrane F A D H 2 from the outer membrane NADH in mitochondria NADH in mitochondria proton gradient across thylakoid
The energy to power the light-independent reactions, also known as the Calvin cycle, primarily comes from NADPH, which is generated from the light-dependent reactions in the thylakoid membrane. NADPH carries high-energy electrons that are used in the reduction of carbon dioxide during the Calvin cycle. Additionally, ATP generated during the light-dependent reactions also provides energy for the light-independent reactions.
