PHOTOSYNTHESIS and CELLULAR RESPIRATION. How energy is made within…. Photo = light Synthesis = to make. Photosynthesis. Converting light energy into glucose. Which of these is the correct photosynthesis formula?. 6CO ₂ +6H₂O = O₂ + C₁H₂₆O₆ C₆H₁₂O₆ + Light Energy + 6CO ₂  6H₂O - PowerPoint PPT Presentation


  • PHOTOSYNTHESIS and CELLULAR RESPIRATIONHow energy is made within..

  • Converting light energy into glucosePhoto = lightSynthesis = to make

  • Which of these is the correct photosynthesis formula?6CO +6HO = O + CHOCHO + Light Energy + 6CO 6HO 6CO +6HO + Light Energy CHO + 6O6O +6HO + Light Energy CHO + 6CO[Default][MC Any][MC All]


  • I. Biochemical PathwaysA series of reactions where one must depend on anotherEx: your kidneys must wait on you to drink fluids

  • II. Light AbsorptionPhotosynthesis (light reactions) occur in chloroplastLight waves travel as wavesIt appears white but is reallyROYGBIV

  • If you are wearing a white shirt. What is happening with the visible light spectrum?You are absorbing all of the colorsYou are reflecting all of the colorsNothing, white is a color on the visible light spectrumNone of these is true[Default][MC Any][MC All]

  • Which of the following is true?A thylokoid within the chloroplast represent a stack of grana.Granum within the chloroplast represent stacks of thylakoids.Chloroplast are green in colored because they have green pigment inside of them called chlorophyll.All of these are trueB and C are true[Default][MC Any][MC All]

  • 3. PigmentsA. These subtract from spectrum allowing you to see specific colors1. chlorophyll a = yellow/green reflected2. chlorophyll b = blue/green reflected

  • III. Photosynthesis Reactions for most plantsA. Light Dependent ReactionB. Calvin Cycle (C) (light independent Reaction)In Thylakoid MembraneNeeds SunByproducts:ATP O NADPH to send to Calvin CycleOccurs in StromaNeeds SunCarbon Fixation occurs (putting carbon into molecules)Byproducts: HOCHO RuBP to restart cycle

  • Which of the following is true of biochemical pathways?C-4 and C-3 pathways are biochemical pathways that are waiting on the Calvin Cycle.The Calvin cycle needs the light dependent reaction to occur so that it may occur, they are both dependent on each other.The Calvin cycle is not part of photosynthesis and therefore not a part of a biochemical pathway.None of these are true.[Default][MC Any][MC All]

  • Calvin CycleMust make 3 rounds to produce1 molecule of Glucose with 6 carbon atoms

  • Carbon FixationWhen carbon atoms are bonded or fixed into an organic compoundEx. CO CHO

    The Calvin Cycle is also known as C pathwayCO fixed into 3-C compound

  • How many rounds must the Calvin cycle make to be able to produce just one macromolecule of glucose?13 because it gets 2 carbons each time6 because glucose has 6 carbonsI really have no idea

  • IV. Alternate PathsC PathwayCAMCO fixed into 4-C compoundHot and Humid ClimatesLose amt of water Ex. Sugarcane, Corn, CrabgrassTake in CO at night and fixHot and Dry Climates like DesertEx. Pineapple, Cacti

  • Do all plants fix carbon in the same manner?YesNoWhat are the alternative ways?

  • V. Rate of PhotosynthesisRate is affected by:1.

    2. Temp

    3. Carbon Dioxide

  • Which alternative pathway would many of our plants in our hot and humid region use?CAMC 4 pathwayC 3 pathwayCalvin Cycle

  • If the amount of light intensity increases, the rate of photosynthesis will increase.TrueFalse

  • How animals make energy or ATP..

  • Cellular Respiration and Photosynthesis RelationshipThey are opposites in the energy world even

    CR occurs in animals in the mitochondria

    PS occurs in plants in the chloroplast



  • How are cellular respiration and photosynthesis similar?The both must take in carbon dioxide and release oxygen to produce energy.They are both trying to produce energy within a cell while reciprocating their equations.One process provides energy while the other uses energy.They have no relationship at all.

  • Cellular RespirationThere are 3 main cycles where ATP is produced:

  • Cellular respiration occurs in which part of the cell?The cytoplasmThe thylakioidThe mitochondriaOutside of the cell

  • Anaerobic vs. Aerobic

    Anaerobic do not require OxygenGlycolysisFermentation (ATP not made)Aerobic requires Oxygen to make ATPKrebs CycleETC (Electron Transport Chain)

  • GlycolysisNet Gain:

    2 ATPs2 NADHs2 Pyruvates/pyruvic acid

  • Is glycolysis a very efficient ATP producer?YesNo

  • Which of the following is true of aerobic and anaerobic respiration?Anaerobic means that oxygen must be present for a cycle to occur.Anaerobics is an exercise program for adults.Glycolysis is anaerobic because it does not require oxygen to make ATPNone of these

  • BY-PASSAfter Glycolysis,

    NADH cannot enter Mitochondria so they pass extra H back to Pyruvate, now NAD enters

  • AlcoholicLactic AcidUsed for:Yeast in breadWineSauerkrautProducts:CONADAlcohol

  • What is true of fermentation?It does not play a role in making ATP.It is a stage where some cells go to but is not a main portion of cellular respiration.It is a bypass stage, but is still important to us in different ways.All of these

  • FermentationBakers use the yeast made in alcoholic fermentation to make breadLactic acid made in the muscles start breaking down the muscles

  • Before Krebs Cycle but after Glycolysis Before it can begin it must convert pyruvate into a more usable form.This Nets 2 NADHs

    2 Pyruvic Acids 2 Acetyl CoAs

  • Which of the following is not true?Alcoholic fermentation can be used to make wine.Yeast is used to make bread rise.Lactic acid builds muscles not oxygen.Lactic acid is produced in muscles when over worked.

  • Krebs CycleOccurs in mitochondriaStarts with 1 Acetyl CoA

  • Why must glycolysis occur before Krebs cycle?Because these cycles are contingent on one another, meaning that one must occur producing something that the next needs.These are biochemical cycles.Glycolysis produces pyruvates, which inadvertently are used to start Krebs cycle.All of these

  • How many Acetyl CoAs was actually madeSo how many rounds does the Krebs cycle make?

  • Krebs Cycle

  • Is the Krebs cycle a very efficient ATP producer?YesNo

  • Electron Transport Chain (ETC)AKA Oxidative PoshorylationLooks like Fluid Mosaic Model

  • How many ATP did glycolysis Net?1234

  • How many ATP did the Krebs cycle net?1234

  • ETC Summary

  • ETC

  • Energy Yield for 1 average cell in your body
