Avg score: 74% • Most missed: “How many carbon atoms does OAA contain?”

The electrons and protons are used to produce NADPH (the reduced form of nicotine adenine dinucleotide phosphoric acid) and ATP (adenosine triphosphate). ATP and NADPH are energy storage and electron carrier/donor molecule. Both ATP and NADPH are used in the next stage of photosynthesis.
