InstructionPhotosynthesis and Cellular RespirationSlide2Energy Flow through the Biosphere Energy comes from the Sun and gets trapped or converted by the. Thethen eat those producers. So,flows from thethrough the producers to theconsumers.4Focus on Photosynthesiscaptures energy from the Sun and stores it as glucose. Overall photosynthesis reaction equation:6CO2 6H2O Light-energy 6O2 C6H12O6reactions: Chloroplasts capture solar energy,water molecules are split, electrons are transported, H ions are released,andis made. Light-reactions: Calvin cycle uses energy in ATPto add carbon dioxide to carbon-based molecules to make. Edgenuity, Inc.4

Overall cellular respiration reaction equation:6O2 C6H12O6 6CO2 6H2O : energyglucose into pyruvate and makes ATP.: Forms citric acid and breaks it down to formcarbon dioxide and make .transport chain: ElectronsH ionsacross a membrane. H ions then produce more ATP and combinewith oxygen to form water.6Specialized OrganellesFill in the boxes to label the organelles.Photosynthesis Edgenuity, Inc.Cellular Respiration5

InstructionPhotosynthesis and Cellular RespirationSlide9Chemical Reaction Cycles Photosynthesis includes thecycle, which fixes carbon dioxideinto glucose. Cellular respiration includes thecycle which breaks downglucose, eventually producing ATP.Uses of ATP and Electron Transport ChainsPhotosynthesis and cellular respiration use:: Cellular respiration and photosynthesis produce and use ATP tocarry energy for the various reactions within each process. uses the ATP produced to synthesizeglucose. creates a net positive amount of ATPafter breaking down glucose. Electronchain: Both reactions use carrier molecules totransport electrons. Photosynthesis uses the chainwhen sunlight energizeselectrons. Cellular respiration uses the chain Edgenuity, Inc.after glucose is broken down.6
