Which of the following sequences correctly represents the flow of electrons during photosynthesis? a. nadph -> o2 -> co2b. h2o -> nadph -> calvin cyclec. nadph -> chlorophyll -> calvin cycled. h2o -> photosystem i -> photosystem iie. nadph -> electron transport chain -> o2

Answer;

H2O -> NADPH -> Calvin cycle

Explanation;Electrons are transferred sequentially between the two photosystems, with photosystem I acting to generate NADPH and photosystem II acting to generate ATP. The Calvin cycle is part of photosynthesis, which occurs in two stages. In the first stage, chemical reactions use energy from light to produce ATP and NADPH. In the second stage, carbon dioxide and water are converted into organic molecules, such as glucose. During the Calvin cycle electrons stored in NADPH are used to reduce carbon. Using the ATP and NADPH made during the light reactions, carbon is reduced in the Calvin cycle and sugar is made.

Okay this will take 1 hour okay dont forget me.
