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

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]

8.3 DATA ANALYSIS 1-ANALYZE how did the virus affect lactic acid production in the cells? -virus increased lactic acid production after 4 hours

8.3 DATA ANALYSIS 2- CALCULATE After 8 hours what percentage was the lactic acid higher in the virus group than in the control group? By what percentage was ATP production decreased? -lactic acid increased ~75% [7 - 4=3 : 3/4 = .75] -ATP production decreased ~28% [7 – 5 = 2 : 2/7 = .28]

8.3 DATA ANALYSIS 2- INFER why having a virus like the flu might make a person feel tired. -decreased ATP synthesis

8.3 CELLULAR RESPIRATION WHAT YOU WILL LEARN: -product of each stage of cell resp -the role of electron carriers in cell resp -the difference between alcoholic fermentation and lactic-acid fermentation "Cell Respiration"

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

OVERVIEW of CELLULAR RESPIRATION -FUNCTION of cellular respiration— makes ENERGY for cells LIST organisms that carry out CELLULAR RESPIRATION? - plants / animals / prokaryotes LIST the organelle where cellular respiration takes place --- - mitochondria IDENTIFY the chemical equation for cell respiration: -C6H12O6 + 6O2  6CO2 + 6H2O + energy

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

STEP 1-GLYCOLYSIS breaks down glucose cytoplasm anaerobic - NO O2 needed needs 2 ATP molecules to start EACH GLUCOSE MOLECULE NETS: 2 ATP molecules 2 NADH 2 molecules of pyruvate

STEP 2-KREB’S CYCLE breaks down pyruvate -- forms CO2 mitochondria of cell aerobic - requires O2 EACH MOLECULE GLUCOSE PRODUCES: 2 ATP 8 NADH 4 CO2

STEP 3-ELECTRON TRANSPORT ATP made from high-energy electrons & protons mitochondrial membrane aerobic - requires O2 EACH GLUCOSE MOLECULE PRODUCES: 32 ATP electrons & protons w/O2  make H2O

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