Question

hb unit 2.1 cell energy and photosynthesis quiz 2025 (connected module8) which of the following is not a step in the light - dependent reactions? high - energy electrons move through the electron transport chain. atp and nadph are used to produce high - energy sugars. atp synthase allows h+ ions to pass through the thylakoid membrane. pigments in photosystem ii absorb light.

Explanation:

In light - dependent reactions of photosynthesis, high - energy electrons move through the electron transport chain, ATP synthase allows H+ ions to pass through the thylakoid membrane, and pigments in photosystem II absorb light. The use of ATP and NADPH to produce high - energy sugars occurs in the light - independent reactions (Calvin cycle), not in the light - dependent reactions.

Answer:

ATP and NADPH are used to produce high - energy sugars.
