Transcript Respiration
Warm-Up # 12 12/7/12 1) Where do light dependent reactions take place? 2) How are the equations of respiration and photosynthesis similar? 3) List the three parts of ATP. 4) Photosynthesis is to chloroplasts as cell respiration is to_____________. 5) Where on the ATP molecule is a bond broken to make ADP? Respiration Unit 5 What are we doing? • Essential Question: – Could Cellular Respiration take place if plants were not available? • Objectives: • Explain Cellular Respiration • Describe what happens during glycolysis • Name two types of fermentation We Need Plants, We Need Food • Photosynthesis is directly related to Cellular Respiration. • Final products of photosynthesis is used for cellular respiration. • They form a cycle that stays fairly constant. We Use Each Other… • PHOTOSYNTHESIS EQUATION: 6CO2 + 6H2O + LIGHT ENERGY C6H12O6 + 6O2 • CELLULAR RESPIRATION EQUATION: C6H12O6 + 6O2 6CO2 + 6H2O + ENERGY RELEASED (ATP) Organic compounds Glycolysis Fermentation (anaerobic) ATP Aerobic respiration ATP Cellular Respiration • The process that releases energy by breaking down glucose and other food molecules in the presence of oxygen • Three Main Stages • Main goal to produce ATP Stage 1 • GLYCOLYSIS-process in which one molecule of glucose is broken in half producing two molecules of Pyruvic Acid • 2 ATP go in (to get things going) 4 ATP are produced • NADH is made from NAD+ (helps energy get passed along) • Happens in the Cytosol/Cytoplasm Two Types of Cellular Respiration AEROBIC-PRESENCE OF OXYGEN (Also can be called Respiration) ANAEROBIC-ABSENCE OF OXYGEN (Also can be called Fermentation) Stage 2 (WITH OXYGEN) • RESPIRATION • Uses oxygen to release energy • Happens in the Mitochondria. • Pyruvic acid is passed and broken down in the Kreb’s/Citric Acid Cycle Stage 2 (Without Oxygen) Anaerobic respiration/Fermentation. • Lactic Acid Fermentation • Animals—produced in your muscles (sore) • End product is lactic acid and NAD+ • Pickles, yogurt, cheese • Alcoholic Fermentation • Yeast and few other microorganisms • Makes is ethyl alcohol and carbon dioxide • Bread Electron Transport Chain • Converts ADPATP • Produces the most ATP (32 or 34) • Occurs on cristae of mitochondria • Electrons pass from one acceptor giving off energy. • Final electron acceptor is oxygen making water. Energy Tally • 36 ATP for aerobic vs. 2 ATP for anaerobic – Glycolysis – Kreb’s – Electron Transport 2 ATP 2 ATP 32 ATP 36 ATP • Anaerobic organisms can’t be too energetic but are important for global recycling of carbon Cellular Respiration Breakdown FUNCTION Energy Release Location Mitochondria Reactants (What goes C6H12O6 and O2 in) Products (What comes CO2 and H20 out) 602+C6H12O66CO2 Equation +6H2O Word Bank: 2 ATP 32/34 ATP 4 NADH 1 FADH Alcohol Fermentation Electron transport chain Ethyl Alcohol Mitochondrion Cytoplasm/cytosol Fermentation Glycolysis Glucose Pyruvate/Pyruvic Acid Lactic acid Lactic Acid Fermentation Kreb's Cycle Unit 5 Study Guide • FINISH the respiration part of the study guide now • Whatever you do not finish is homework • QUIZ TOMORROW!!!
