Energy: Cellular Respiration MITOCHONDRIA

What is produced from eating food (heterotrophs) or made by plants (autotrophs) that is necessary for cellular respiration? GLUCOSE

Photosynthesis Reactants of one are products of the other!!!! Cellular Respiration Products

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!!!! NADH 1 Glycolysis 2 ATP 2 Kreb’s Cycle 3 Electron Transport Chain

Glycolysis takes place in the cytoplasm and needs 2 ATP 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) Glycolysis in Cytoplasm PGAL

CYTOPLASM Oxygen present 2 Pyruvates Cellular Respiration (aerobic) Oxygen not present Anaerobic Fermentation (Lactic Acid or Alcoholic)

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+

All Eukaryotes!!!!

GLYCOLYSIS – In Cytoplasm STEP #1 Mitochondria Space Inner Membrane Kreb’s Cycle takes place in the SPACE of the Mitochondria STEP #22 STAGE Electron Transport Chain takes place in the INNER MEMBRANE of the Mitochondria STAGE 3 STEP #3 Hint: “Cycle takes place in the SPACE”

What is Step #2 called and what products are made? CO₂, NADH, FADH₂, 2 ATP Charged Battery Charged Batteries NADH FADH 2 2 1 Kreb’s Cycle Glycolysis 2 Pyruvates Citric Acid Cycle CO₂ out 2 ATP

Step #3: What is this process called and what products are made? What is the essential reactant? Charged Battery NADH FADH 2 NADH 2 1 Kreb’s Cycle Glycolysis 2 Pyruvates Citric Acid Cycle 3 O₂ in Electron Transport Chain H₂O out CO₂ out 2 ATP 32 ATP

REMEMBER: Electron Transport Chain Lucy and Ethel represent the OXYGEN needed Candy represented the Hydrogen present Wrapped Candy represent the WATER being produced Oxygen H₂O H+

What part of cellular respiration produces the most energy (ATP)? Electron Transport Chain 32 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 Step 1 2 ATP Step 2 32 ATP Step 3 = 36

Cellular Respiration - Overview Obtain Glucose from eating or photosynthesis Glycolysis Kreb’s Cycle Electron Transport Chain Where does this take place? Cytoplasm Space (Matrix) of Mitochondria Membrane of Mitochondria Glucose 2 Pyruvates O₂ What are the reactants? What are the products? How many ATP’s are made? ADP & ATP NAD+ FAD 2 Pyruvates ATP NADH ATP CO₂ NADH FADH₂ 2 ATP’s FADH₂ NADH H₂O ATP 32 ATP’s
