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 phosphorylation?Practice QuestionsBefore testing yourself with this worksheet, please review your notes on cellular respiration and photosynthesis. You should be able to answer all questions without the use of your notes.1.Draw and Label the following:MitochondrionChloroplastKranz Anatomy ( omit for Matric)2.Make a flow chart showing the flow of energy between photosynthesis and cellular respiration.QuestionAnswer3.
