Question

How do I summarize this ?
NADPH carries the electrons and their energy to the next phase, the light-independent reactions.

Answer 1

Well how do I rewrite it differently ?

Answer 2

Step wise..
Like what is the first step of krebs cycle..

Steps 1-4

In the first step, coenzyme A transfers a two-carbon acetyl group to the oxaloacetate, a four-carbon compound. This forms the six-carbon molecule citrate. In step two, the citrate rearranges to form six-carbon isocitrate. Then, the isocitrate is oxidized and a carbon dioxide molecule is removed. The result is a five-carbon molecule alpha-ketoglutarate and the reduction of NAD+ to NADH and H+. In the fourth step, the alpha-ketoglutarate is oxidized, carbon dioxide is again removed, and coenzyme A is added. This forms the four-carbon compound succinyl-CoA. Like the prior step, during oxidation, NAD+ is reduced to NADH and H+.

Steps 5-8

In step five, coenzyme A is removed from succinyl-CoA, resulting in the production of succinate. Then, succinate is oxidized to form fumarate. In step seven, water is added to the fumarate, resulting in malate. Finally, malate is oxidized, resulting in oxaloacetate. During this final oxidation, NAD+ is reduced to NADH and H+. For each Krebs Cycle, two molecules of carbon dioxide are formed and oxaloacetate is regenerated. This process allows for the next stage of glucose oxidation.
