Text of Photosynthesis vs. Cellular Respiration

  • Photosynthesis vs. Cellular RespirationCellular Energy & Biochemistry Chapter 5

  • Photosynthesis(autotrophs)

    CO2 + H2O C6H12O6 + O2Carbon dioxide Glucose && water oxygen


  • Energy CyclePhotosynthesisRespirationAutotrophsHerbivoresCarnivores

  • Releasing Energy from Foods

  • What is the function of photosynthesis?Energy storage Converts light energy to chemical energy in the form of glucose.

  • What are the two stages of photosynthesis? Light CalvinReactions Cycle

    requires light light independent

  • What is the formula for glucose?


  • Where in the cell does photosynthesis take place?Thylakoid membranes of chloroplasts.

  • Where in the chloroplast does the Calvin cycle take place?

    Grana of chloroplast

  • What is the equation for Photosynthesis?6CO2 + 6H2O C6H12O6 + 6O2

  • What are the reactants of Photosynthesis?CO2 and H2O

  • What are the products of Photosynthesis?C6H12O6 and O2

  • What is the function of Cellular Respiration?Energy release Breaks down glucose to form ATP for cellular activities

  • Cellular RespirationGlycolysis (yields ATP)

    Aerobic Anaerobic(oxygen)(w/o oxygen) fermentation

    Yields 21- 36 Yields 2 ATPATP

  • Anaerobic Respiration Alcohol Lactic AcidFermentation Fermentation

    Alcohol & CO2 Lactic acid + CO2

    baking, sours milk, brewing muscle fatigue

  • What is glycolysis and where does it take place?Glycolysis breaks down glucose into pyruvic acid in the cytoplasm

  • How many molecules of ATP does glycolysis produce?2 molecules of ATP

  • How many molecules of ATP does Cellular Respiration produce?Glycolysis 2 ATPAerobic + 36 ATPTotal 38 ATP

  • Where in the cell does Cellular Respiration take place?Mitochondria 2 membrane (outer and inner folds cristae)

  • Energy Release/Storage CycleATP= Adenosine Tri Phosphate (A-P-P-P)ADP = Adenosine Di Phospate (A-P-P) A-P-P - P energy energystorage releaseA-P-P + P

  • What is the equation for Cellular Respiration?C6H12O6 + 6O2 6CO2 + 6H2O (+ Energy in form of ATP)

  • What are the reactants of Cellular Respiration?C6H12O6 and O2

  • What are the products of Cellular Respiration?CO2 and H2O
