All cells go through cellular respiration----plant and animal cellsi. GLYCOLYSIS1. 1st step of cellular respiration2. Cells break down glucose to make 2 ATP and pyruvic acidGlycolysis SummaryGlucose ( ( Net 2 ATPChemical reactions requiring ATP, ADP and phosphateAerobic versus Anaerobic Respiration Is Oxygen Present? Yes NoAEROBIC RESPIRATION ANAEROBIC RESPIRATIONMust have O2 No O2 is neededTakes place in the takes place in the mitochondria cytoplasmProduces 36 ATP produces 2 ATP c.Aerobic Respirationi. Occurs only when oxygen is presentii. A series of reactions that change pyruvic acid into ATP1. the Krebs cycle or the citric acid cycle takes place in the mitochondria i. It produces 2 ATP2.The electron transport chain also takes place in the mitochondria and it produces 34 ATPiii. With glycolysis, aerobic respiration produces 36 NET ATP molecules from 1 glucose---2 ATP are used to drive the processSection 9-2Electron TransportHydrogen Ion MovementATP ProductionATP synthesesChannelInner MembraneMatrixIntermembrane SpaceGo to Section:Mitochondrioniv.

The electron transport chain also takes place in the mitochondria and it produces 34 ATPii. Produces 36 NET ATP molecules from 1 glucose---2 ATP are used to drive the processiii. ATP is used for cell processes, growth, repair, movement, homeostatsis etcb. Anaerobic Respriationi. Occurs when no oxygen is presentii. Not very effiecient---only produces 2 ATP molecules from one glucoseiii. There are different types of anaerobic respiration1. Lactic Acid Fermentation-animal and some bacteria use this processa. Produces lactic acid (causes muscle soreness) and 2 ATP2. Alcoholic Fermentation-plant cells and some microorganism like yeastAerobic Respiration Summary (including glycolysis)Glucose ( chemical reactions requiring ( NET 36 ATP, CO2, & H2O ADP, ATP, phosphate & O2Aerobic Respiration (Net Reaction)_______________ + __________ ( _______ + _________ + _____ glucose oxygen carbon water energy dioxided.Anaerobic Respirationi. Occurs when no oxygen is presentii. Not very efficient---only produces 2 ATP molecules from one glucoseiii. There are different types of anaerobic respiration1. Lactic Acid Fermentation -animal and some bacteria use this processa. Produces lactic acid (causes muscle soreness) and 2 ATP2. Alcoholic Fermentation -plant cells and some microorganism like yeasta. Produces ethyl alcohol and CO2 and ATPAlcoholic drinks are produced with fermentation, and bread is forced to rise from the carbon dioxide produced by yeast fermenting the bread. The alcohol in bread is evaporated during the cooking process.GlucoseGlycolysis Krebs cycle Electron transportAlcohol or lactic acidSection 9-1Go to Section:Fermentation (without oxygen)a. ATP2. Alcoholic Fermentation-plant cells and some microorganism like yeasta. Produces ethyl alcohol and CO2 and ATP Photosynthesis and cellular respiration are almost exactly opposite reactions:Photosynthesis reaction:____________ +_____________ + _______________ ( __________ + _____________Respiration____________ +_____________ ( __________ + _____________ + ______________Anaerobic Respiration (Net Reaction) enzymes _____________ glucose Anaerobic Respiration Summary (including glycolysis)_____________ ( chemical reactions ( Net 2 ATP Photosynthesis and respiration are almost exactly opposite reactions.Photosynthesis:6CO2 + 6H2O + sun light C6H12O6 + 6O2Respiration:C6H12O6 + 6O2 6CO2 + 6H2O + ATP Cellular RespirationPhotosynthesisTakes place in--Occurs when--What goes in?What comes out?Energy source?Result?Cellular RespirationPhotosynthesisTakes place in--All cellsCells withChloroplastOccurs when--All of the timeIn the presence of lightWhat goes in?Carbohydrates and oxygenCO2 and H2OWhat comes out?CO2 and H2OCarbohydrates and oxygenEnergy source?Chemical bondsLightResult?Energy is stored as ATPEnergy is stored as carbohydratesCopy and CompleteWhat is the process that starts cellular respiration?Name three parts of aerobic respiration.How many ATP molecules are produced from one glucose molecule by glycolysis?Most of aerobic respiration occurs in the ____.Anaerobic respiration occurs in the___.During glycolysis, glucose is broken down into pyruvic acid, and two molecules of ATP are formed. What will happen next in a muscle cell if NO oxygen is present?When yeast is deprived of oxygen, it will convert glucose intoWhich process does NOT produce CO2?How many ATP molecules are produced form one glucose molecule during the entire process of aerobic respiration?How many net ATP molecules are produced from one glucose molecule if a cell undergoes anaerobic respiration?*********************
