The answer for your question is C
<span>The correct answer is: It is used to synthesize ATP through substrate-level phosphorylation.</span>
<span>The free energy released as electrons are passed from photosystem II to photosystem I drive pumping of H+ and building a gradient. H+ flow down their gradient and when they pass through ATP synthase, the ATP is produced by substrate-level phosphorylation (ADP+Pi).</span>
Meiosis produces 4 haploid cells. In meiosis you start with a diploid cell that divides twice to produce four haploid cells.
Hope this helps! =^-^=
