1. 8.3 READ Qs 1- IDENTIFY In the Kreb’s cycle what is pyruvate converted to? 2- IDENTIFY: Complete the figure by writing the location of each stage of cell respiration -carbon dioxide -cytoplasm -mitochondria -mitochondria membrane

2. 8.3 READ Qs 3- DEFINE What 2 processes make up anaerobic respiration? 4- CLASSIFY What type of organisms have cells that carry out all of the process shown? -glycolysis -fermentation -plants [autotrophs]

3. 8.3 CELLULAR RESPIRATION WHAT YOU WILL LEARN: -the role of electron carriers in cellular respiration -the difference between alcoholic fermentation and lactic-acid fermentation "Cell Respiration"

4.  MAIN IDEA -Living organisms obtain energy breaking down organic compounds during cellular respiration

5.  OVERVIEW of CELLULAR RESPIRATION -FUNCTION of cellular respiration—  makes ENERGY for cells LIST organisms that carry out CELLULAR RESPIRATION? - plants / an imals / prokaryotes LIST the organelle where cellular respiration takes place --- mitochondria IDENTIFY the chemical equation for cell respiration: -C 6 H 12 O 6 + 6O 2  6CO 2 + 6H 2 O + energy

6.  OVERVIEW of CELLULAR RESPIRATION IDENTIFY energy form used during cell respiration  chemcial  light  mechanical IDENTIFY energy form produced during cell respiration  chemcial  light  mechanical DETERMINE total energy produced during cell resp-- -ATP = __________ -NADH + = __________ cellular respiration (SUGAR GOES TO ATP) ~36 ~10

10.  ANAEROBIC RESPIRATION-NO O2 CAUSE: CELLS CAN’T GET ENOUGH OXYGEN FERMENTATION FOLLOWS: GLYCOLYSIS IT REPLACES: KREB’S CYCLE AND ELECTRON TRANSPORT FERMENTATION IS NEEDED TO REPLENISH SUPPLY OF NAD+ FOR GLYCOLYSIS  2 ATP

11.  STEP 1-GLYCOLYSIS  breaks down glucose  Occurs in cytoplasm of cells anaerobic process—NO O 2 needed  needs 2 ATP molecules to start EACH GLUCOSE MOLECULE NETS:  2 ATP molecules  2 NADH  2 molecules of pyruvate

12.  STEP 2-KREB’S CYCLE  breaks down pyruvate -- forms CO 2  Occurs in mitochondria of cell  aerobic process—requires O 2 EACH MOLECULE GLUCOSE PRODUCES:  2 ATP  8 NADH  4 CO 2

13.  STEP 3-ELECTRON TRANSPORT  ATP made from high-energy electrons & protons  Occurs in mitochondrial membrane aerobic process—requires O 2 EACH GLUCOSE MOLECULE PRODUCES:  32 ATP  electrons & protons w/O 2  make H 2 O

14.  ANAEROBIC RESPIRATION-FERMENTATION NO O2 present-- LACTIC ACID FERMENTATION -produced in muscles during strenuous exercise—not enough O 2 -lactic acid produced by many microorganisms -used in making yogurt, sour cream, cheese ALCOHOL FERMENTATION -used in making beer & wine/bread -occurs in organisms such as bacteria/yeast
