Can someone reword this for me? Please and thank you!

Cellular respiration is a process that converts energy from food molecules into the energy of ATP. It involves three stages that occur in the cytoplasm of cells and in the mitochondria. One of the three stages is the citric acid cycle which is a series of reactions that generates reduced electron carriers that transport electrons to the electron transport chain. Since the primary function of the mitochondria is to produce ATP, the citric acid cycle most likely occurs in the mitochondria. To test this hypothesis, the cellular components from cauliflower, namely the nuclei and the mitochondria, were separated using differential centrifugation. The oxidation of succinate to fumarate catalyzed by succinate dehydrogenase is a reaction that is part of the citric acid cycle. This reaction was utilized along with an artificial electron acceptor DCIP. When reduced, DCIP turns from a blue/violet color to a clear solution. DCIP absorbs light most efficiently as 410 nm and the change in absorbance over time was used to show that the citric acid cycle occurs in the mitochondria.
