carries electrons to the ETC

Detailed explanation-1: -NADPH will travel to the Calvin cycle, where its electrons are used to build sugars from carbon dioxide.
Detailed explanation-2: -In the second stage, ATP and NADPH are used to convert the 3-PGA molecules into molecules of a three-carbon sugar, glyceraldehyde-3-phosphate (G3P). This stage gets its name because NADPH donates electrons to, or reduces, a three-carbon intermediate to make G3P.
Detailed explanation-3: -Related Biology Terms NADPH – The reduced version of NADP+, which serves as a proton donor and electron carrier. NADH – NADPH without an extra phosphate group, used mostly in catabolic reactions.
Detailed explanation-4: -The chloroplasts present in the plants also use NADPH as a part of the pathway to synthesize sugars from the sunlight and also from the carbon dioxide. Likewise, in other reactions, NADPH carries electrons and protons into the new carbon-carbon bonds, creating sugar molecules.
Detailed explanation-5: -At the end of a short second electron transport chain, NADP+ molecules in the stroma pick up the high-energy electrons and H+ ions at the outer surface of the thylakoid membrane to become NADPH.
