Paragraph в I A + v ...Question 54 Electron transport and chemiosmosis (is the movement of ions across a semipermeable membrane, down their electrochemical gradient.) occur during both aerobic cell respiration and photosynthesis. What is the purpose of electron transport and chemiosmosis in both cell respiration and photosynthesis? O To create sugar molecules from oxygen gas O To create water molecules from carbon dioxide gas OTo use the energy released from slowing electrons to build ATP OTo usc he energy released from slowing electrons to create lightThe following data is for the oxidation of catechol (the substrate) to o-quinone by the enzyme o-diphenyl oxidase. Additional data is also provided for when the reaction is run in the presence of Phenylthiourea. All data was acquired by monitoring the change in absorbance at 540 nm. Die volgende data is vir die oksidasie van katekol (die substraat) na o-kinoon deur die ensiem o- difenyloksidase. Bykomende data word ook verskaf vir wanneer die reaksie uitgevoer word in die teenwoordigheid van Phenylthiourea.
