  • Slide 1
  • ADP, ATP and Cellular Respiration
  • Slide 2
  • What Is ATP? Adenosine Triphosphate Molecule containing high-energy Phosphate bonds
  • Slide 3
  • Chemical Structure of ATP 3 Phosphates Ribose Sugar Adenine Base Copyright Cmassengale
  • Slide 4
  • What Does ATP Do for You? It supplies YOU with ENERGY! Copyright Cmassengale
  • Slide 5
  • How Do We Get Energy From ATP? By breaking the high- energy bonds between the last two phosphates in ATP Copyright Cmassengale
  • Slide 6
  • What is the Process Called? HYDROLYSIS (Adding H 2 O) H2OH2O Copyright Cmassengale
  • Slide 7
  • How Does That Happen? An Enzyme! Copyright Cmassengale
  • Slide 8
  • How is ATP Re-Made? The reverse of the previous process occurs. Another Enzyme is used! ATP Synthetase Copyright Cmassengale
  • Slide 9
  • The ADP-ATP Cycle ATP-ase ATP Synthetase Copyright Cmassengale
  • Slide 10
  • When is ATP Made in the Body? During a Process called Cellular Respiration that takes place in both Plants & Animals Copyright Cmassengale
  • Slide 11
  • Cellular Respiration Includes pathways that require oxygen Includes pathways that require oxygen Breakdown of one glucose molecule produces 36 ATP molecules Breakdown of one glucose molecule produces 36 ATP molecules Copyright Cmassengale
  • Slide 12
  • Overall Equation for Cellular Respiration 6CO 2 + 6H 2 0 + 36 ATPs C 6 H 12 O 6 + 6O 2 YIELDS
  • Slide 13
  • Important Molecules in Cellular Respiration CO 2 Carbon Dioxide ATP Adenine triphosphate NAD Nicotinamide adenine dinucleotide FAD Flavin adenine dinucleotide
  • Slide 14
  • What are the Stages of Cellular Respiration? STEP 1 - Glycolysis STEP 1 - Glycolysis STEP 2 - The Krebs Cycle STEP 2 - The Krebs Cycle STEP 3 - The Electron Transport Chain (ETC) STEP 3 - The Electron Transport Chain (ETC)
  • Slide 15
  • Where Does Cellular Respiration Take Place? It actually takes place in two parts of the cell: It actually takes place in two parts of the cell: Glycolysis occurs in the Cytoplasm Krebs Cycle & ETC Takeplace in the Mitochondria Krebs Cycle & ETC Take place in the Mitochondria
  • Slide 16
  • Mitochondria Structure Smooth outer Membrane Smooth outer Membrane Folded inner membrane Folded inner membrane Folds called Cristae Folds called Cristae Space inside cristae called the Matrix Space inside cristae called the Matrix
  • Slide 17
  • Diagram of the Process Occurs in Cytoplasm Occurs in Matrix Occurs across Cristae Copyright Cmassengale
  • Slide 18
  • STEP 1 Glycolysis Summary Takes place in the Cytoplasm Anaerobic (Doesnt Use Oxygen) Uses 2 molecules of ATP Glucose split into two molecules of Pyruvic Acid
  • Slide 19
  • Glycolysis Summary Produces 2 NAD and 4 ATP molecules Produces 2 NAD and 4 ATP molecules (2 ATP Used & 4 Produced so overall 2 ATP molecules from glycolysis) (2 ATP Used & 4 Produced so overall 2 ATP molecules from glycolysis) Pyruvate is oxidized to Acetyl CoA and CO 2 is removed Pyruvate is oxidized to Acetyl CoA and CO 2 is removed
  • Slide 20
  • Glycolysis Diagram GLUCOSE (6 Carbon) 2 PYRUVATE (3 Carbon) + 2ATP
  • Slide 21
  • Slide 22
  • Fermentation Occurs when O 2 NOT present (anaerobic) Occurs when O 2 NOT present (anaerobic) Called Lactic Acid fermentation in muscle cells (makes muscles tired) Makes only 2 ATP molecules
  • Slide 23
  • Krebs Cycle Summary Requires Oxygen (Aerobic) Requires Oxygen (Aerobic) Cyclical series of reactions that give off CO 2 and produce one ATP per cycle Cyclical series of reactions that give off CO 2 and produce one ATP per cycle Turns twice per glucose molecule Turns twice per glucose molecule Produces 2 ATP molecules Produces 2 ATP molecules Takes place in matrix of mitochondria Takes place in matrix of mitochondria
  • Slide 24
  • Krebs Cycle Summary Each turn of the Krebs Cycle also produces 3NADH, 1FADH 2, and 2CO 2 Each turn of the Krebs Cycle also produces 3NADH, 1FADH 2, and 2CO 2
  • Slide 25
  • Krebs Cycle ATP NETS: 3NADH, 1ATP, 1FADH 2, & 2CO 2
  • Slide 26
  • Electron Transport Chain Summary 32 ATP Produced 32 ATP Produced H 2 O Produced H 2 O Produced Occurs Across Inner Mitochondrial membrane Occurs Across Inner Mitochondrial membrane Uses coenzymes NAD+ and FAD+ to accept electrons from glucose Uses coenzymes NAD+ and FAD+ to accept electrons from glucose
