= Nicotinamide adenine dinucleotide phosphate
{wiki}
<Nicotinamide adenine dinucleotide phosphate> is a <cofactor> used in <metabolism>. Its oxidized and reduced forms, <NADP+> and <NADPH>, carry <Electrons> between coupled <chemical reactions>. In <oxygenic photosynthesis>, <light-dependent reactions> produce <NADPH> for the <Calvin cycle>, which returns <NADP+> for reuse. https://openstax.org/books/biology-2e/pages/8-3-using-light-energy-to-make-organic-molecules[OpenStax Biology 2e, 8.3: recycling NADP+ and NADPH]{ref}.
