Review of Photosynthesis and Cellular RespirationWhat do you need to know?1. Generalized InformationWhat is ATP, Structure, Uses in the body, How does it release energyWhat is metabolism ( Metabolic Pathway)What is the difference between an anabolic and a catabolic reactionWhat is the difference between oxidation and reduction2. Comparing Photosynthesis and Cellular RespirationGeneralized Reaction for photosynthesis and cellular respirationChloroplast anatomy, Mitochondria anatomyWhich types of cells (plant/ animal) use each processWhat is the purpose of each of these metabolic pathways?3. PhotosynthesisInvolves use of pigments: know chlorophyll a, chlorophyll b and carotene and which wavelength of light each of them works best in.What is the difference between the action spectrum and the absorption spectrum for pigments.Light Dependant Reactions:Know where these reactions occur in the chloroplastKnow the series of events in the Non Cyclic Light Dependant Reactions ( p. 173 in text)What is a photosystem?What is an electron transport system?What is chemiosmosis? How does it work?Know the products that are released ( ATP and NADPH) and where these products will goLight Independent Reactions:Know Alternate names for this pathway ( Calvin-Benson Cycle, Carbon Fixation Cycle)Know the series of events in the Light Independent Reactions ( p.177 text)What is Carbon Fixation? What is PGAL and what are its 2 functions in the cycle?How are ATP and NADPH ( from the L.D.Reactions) Used in the L.I Reactions?4. Cellular RespirationWhat is the difference between aerobic respiration and anaerobic respiration in terms of:Oxygen useEnergy output ( # of ATP)Events of each ( Anaerobic: GlycolysisFermentation) ( Aerobic : GlycolysisKrebs Cycle Oxidative Phosphorylation) Glycolysis:Where does it take place (cytoplasm / cytosol)Know the series of events in Glycolysis (p. 186 text)Does this step require oxygenWhat products are produced ( Net and Gross in Glycolysis)Fermentation:Where does this take place?Know the series of events in fermentation:In Plant Cells (Ethanol Fermentation) – p. 191 textWhat are the uses of the products of ethanol fermentation in society?In Animal Cells(Lactate Fermentation)- p. 190 textWould this be part of aerobic or anaerobic respiration? ATP Yield?Krebs Cycle:Alternate names for the Krebs Cycle ( Citric Acid Cycle, Citrate Cycle)What is decarboxylation? Where does it occur in the Krebs CycleWhere does the Krebs cycle take place?Is it part of aerobic or anaerobic respiration?There is a link reaction between Glycolysis and the Krebs cycle what happens here? ( p. 187 text)Know the series of events in the Krebs cycle ( p. 187 text)What High energy Molecules are formed and how many ( NADH & FADH2) ? What is the value of these molecules? Is their formation an oxidation or a reduction?Are any ATP made? How Many?Oxidative PhosphorylationThis is made up of 2 events: Chemiosmosis and an electron transport system.What does the term oxidative phosphorylation mean? Why is it appropriate for this part of cellular respiration?What happens to the High energy molecules made throughout aerobic respiration at the phase oxidative phosphorylation?What is the end product of oxidative phosphorylationPractice Questions KEYVascular bundleBefore testing yourself with this worksheet, please review your notes on cellular respiration and photosynthesis.

What is meant by decarboxylation?Loss of carbon5. What term is opposite to decarboxylation?Carbon fixation6. What is meant by phosphorylation?Addition of phosphate7. What is meant by lysis?/ Photolysis?Lysis= splitting of a moleculePhotolysis= splitting a molecule with light8. What is the generalized reaction for cellular respiration?C6H12O2 + 6O2 6CO2 + 6H2O + 36 ATP9. What is the generalized reaction for Photosynthesis?6CO2 + 6H2O + Light C6H12O2 + 6O210.In what organelle does cellular respiration occur? Photosynthesis occur?Cell Resp: MitochondrionPhotosyn: Chloroplast11.What reaction steps make up Anaerobic Respiration In a plant? In an animal?? Plant: Glycolysis + Alcohol FermentationAnimal: Glycolysis + Lactate Fermentation12. What reaction steps make up Aerobic Respiration?Glycolysis + Krebs Cycle(includes Link Rxn) + Oxidative Phosphorylation13.What reaction steps make up photosynthesis?Light Dependent Reaction (Non-Cyclic or Cyclic) + Light Independent Reactions14. What is chemiosmosis?The activation of ATP synthase as hydrogen passes through a chemiosmotic channel. This allows ADP + P to be combined to form ATP15.Identify three main groups of pigments involved in photosynthesis.Chlorophyll aChlorophyll bCarotenoids16. What is the difference between an absorption spectrum and an action spectrum?Abs: the wavelengths of light that a certain pigment absorbsAct: The wavelength of light that is best for photosynthesis17. What is a Photosystem? Reaction Center?A collection of chlorophyll molecules in the thylakoid. The reaction center is one special chlorophyll in the middle of the photosystem18.Identify 3 ways to measure the rate of photosynthesis?-O2 evolved-CO2 taken in- carbohydrate formed19. What is meant by limiting factor? Rate limiting step?The required item that is in the lowest supply / the step in the reaction that is stalled due to the limiting factor.20.Identify 6 environmental affecters of photosynthesis.Light intensity, light wavelength, CO2 levels, temperature, wind velocity, water/mineral supply21. Identify 4 internal affecters of photosynthesisType or concentration of pigments, enzyme or water content, leaf structure or position22. Of the conditions affecting photosynthesis; What are the 3 biggest factors?( List these 3 factors in order of the one that tends to affect photosynthesis the most > least considering our environment.)1. CO2 2. Temperature 3. Light23. Most plants living in temperate climates use a ____ method of photosynthesis. These plants do not do well in ____ conditions, because______. C3 , dry, they close their stomata to conserve water but then can not absorb enough CO2, as a result O2 competes on Rubisco24. Most plants living in tropical climates use a ____method of photosynthesis. They use a different enzyme that _____. These plants also have a unique anatomy called _________.C4 , binds with the O2 so that it does not compete on Rubisco with CO2, Kranz anatomy.25. Most plants living in desert climates use a ______ method of photosynthesis. They use the same method as the plants listed above, except______.CAM , they do their Calvin Cycle until night time, this way they can store up CO226.
