Cellular Respiration Energy For Cells Slide 2 Cellular Respiration Energy is released by breaking the bonds of food molecules (such as glucose) to make ATP from ADP ADP = adenosine diphosphate ADP + P i ATP 2 types aerobic respiration anaerobic respiration Slide 3 Cellular Respiration Slide 4 Aerobic Respiration respiration that requires oxygen Three steps: Glycolysis Krebs Cycle Electron Transport Chain Slide 5 Aerobic Respiration C 6 H 12 O 6 + 6O 2 6CO 2 + 6H 2 O 38 ATP are produced per molecule of glucose 2 ATP are used, so net ATP is 36 Some energy is lost as heat, so the actual number will be lower exergonic reaction energy is released Slide 6 Glycolysis Occurs in the cytoplasm splitting sugar Inputs: glucose Outputs: Pyruvic acid NADH ATP Slide 7 Krebs Cycle Occurs in the mitochondria Inputs: Pyruvic acid Outputs: ATP NADH FADH 2 CO 2 Slide 8 Electron Transport Chain Occurs in the mitochondria Where most of the ATP is produced Inputs: NADH FADH 2 O 2 Outputs: ATP Water Slide 9 Anaerobic Respiration Takes place in the absence of oxygen Occurs in the cytoplasm Fewer ATP are produced net ATP is 2 Similar to glycolysis with an extra step 2 types Lactic acid fermentation Alcoholic fermentation Slide 10 Lactic Acid Fermentation Enzymes break down a glucose molecule into two lactic acid molecules, making ATP C 6 H 12 O 6 lactic acid This process causes the pain in muscle fatigue Slide 11 Lactic Acid Fermentation Slide 12 Alcoholic Fermentation Enzymes break down a glucose molecule into ethanol and CO 2, making ATP C 6 H 12 O 6 2 ethanol + 2 CO 2 This process is used to produce alcohol in gasoline additives in baking Slide 13 Alcoholic Fermentation Slide 14 Photosynthesis vs. Respiration
