What is produced from eating food (heterotrophs) or made by plants (autotrophs) that is necessary for cellular respiration? GLUCOSE
Photosynthesis Cellular Respiration Reactants Products Reactants of one are products of the other!!!!
What is the equation for Cellular Respiration? (Hint: Think Photosynthesis in reverse) Must know this equation!!!!
Once a cell has glucose, what process takes place to convert the glucose into ATP and Pyruvate? Where does this take place in the cell? GLYCOLYSIS IN CYTOPLASM
What type of living things do Glycolysis? STEP #1 of Cellular Respiration All living things do glycolysis!!!! Electron Transport Chain Kreb’s Cycle NADH 2 1 3 2 ATP Glycolysis
Glycolysis takes place in the cytoplasm and needs 2ATP to break 1 Glucose→ 2 PGAL’s NAD+ → NADH (energy carriers) ADP → ATP (chemical energy) 4 ATP’s are made but 2 ATP’s go back into Glycolysis Net 2 ATP’s 2 Pyruvates (Pyruvic Acid) PGAL Glycolysis in Cytoplasm
CYTOPLASM Oxygen present Cellular Respiration (aerobic) Oxygen not present Anaerobic Fermentation Anaerobic Fermentation (Lactic Acid or Alcoholic) 2 Pyruvates
Where does Anaerobic Fermentation (no oxygen) take place? Cytoplasm What organisms do alcoholic or lactic acid fermentation? Alcoholic = Yeast Lactic Acid = Animals (In muscles during short bursts of energy) What is created from fermentation that is needed for Glycolysis to continue making 2 ATP’s? 2 NAD+
GLYCOLYSIS – In Cytoplasm STAGE 2 STAGE 3 Kreb’s Cycle takes place in the SPACE of the Mitochondria Electron Transport Chain takes place in the INNER MEMBRANE of the Mitochondria Mitochondria STEP #2 STEP #3 STEP #1 Hint: “Cycle takes place in the SPACE” Space Inner Membrane
2 2 ATP NADH What is Step #2 called and what products are made? CO₂, NADH, FADH₂, 2ATP Glycolysis 2 Pyruvates 1 Kreb’s Cycle Citric Acid Cycle NADH FADH2 2 ATP CO₂ out Charged BatteryCharged Batteries
23 2 ATP 32 ATP Glycolysis 2 Pyruvates 1 NADH FADH2 CO₂ out O₂ in Electron Transport Chain Step #3: What is this process called and what products are made? What is the essential reactant? H₂O out Charged Battery Kreb’s Cycle Citric Acid Cycle
Lucy and Ethel represent the OXYGEN needed Candy represented the Hydrogen present Wrapped Candy represent the WATER being produced H₂O Oxygen H+ REMEMBER: Electron Transport Chain
Electron Transport Chain 32 ATP What part of cellular respiration produces the most energy (ATP)?
Name the 3 steps of Cellular Respiration in correct order 1.Glycolysis 2.Kreb’s Cycle (Citric Acid Cycle) 3.Electron Transport Chain
What is the total number of ATP made in Cellular Respiration? 2 ATP 32 ATP 2 ATP = 36 Step 1 Step 2 Step 3
Obtain Glucose from eating or photosynthesis GlycolysisKreb’s Cycle Electron Transport Chain Where does this take place? CytoplasmSpace (Matrix) of Mitochondria Membrane of Mitochondria What are the reactants? Glucose ADP & ATP NAD+ 2 Pyruvates NAD+ FAD O₂ FADH₂ NADH What are the products? 2 Pyruvates ATP NADH ATP CO₂ NADH FADH₂ H₂O ATP How many ATP’s are made? 2 ATP’s 32 ATP’s Cellular Respiration - Overview
