Cellular Respiration In the presence of Oxygen, Cells convert energy stored in Glucose into ATP
Aerobic Respiration: Energy is slowly released from glucose to make ATP in the presence of oxygen.
Energy is released from Glucose through “burning” with oxygen. C6H12O6 + 6O2 6CO2 + 6H2O
Energy (in the form of glucose) is supplied by the foods you eat.
Oxygen is supplied by the air you breathe, and Carbon dioxide is released into the atmosphere. O2
Inside your cells, mitochondria use oxygen to release energy from glucose.
Specific chemical reactions occur in each compartment of the mitochondrion.
The most efficient release of energy occurs in three main stages of Cellular Respiration. O2 Pyruvic acid Glucose CO2 H2O
Glycolysis splits glucose into 2 pyruvic acid molecules http://www.science.smith.edu/departments/Biology/Bio231/glycolysis.html
NAD+NADHAn electron carrier • Empty: no electrons • Carrying electrons
The Krebs Cycle releases energy from Pyruvic acid and produces CO2 http://www.science.smith.edu/departments/Biology/Bio231/krebs.html
Electron carriers (NADH & FADH2) generate even more ATP in the Electron Transport Chain. http://www.science.smith.edu/departments/Biology/Bio231/etc.html
Oxidative Phosphorylation Detail (ETC) http://www.youtube.com/watch?v=kN5MtqAB_Yc
ATP Synthase Detail Watch the youtube video to learn how ATP Synthase works. http://www.youtube.com/watch?v=_97mnA_kKds&feature=related
Check for Understanding: Explain why plants must do both, photosynthesis and cellular respiration? Where in the cell does glycolysis, the Krebs cycle and the electron transport take place? What is the final electron acceptor in Oxidative Phosphorylation (ETC)? Which parts of the mitochondria are analogous to the parts of the chloroplast? Explain how they are alike.
Textbook Artist: You have been assigned to illustrate the biochemical pathways involved in cellular respiration. You should include the processes of glycolysis, the Krebs cycle and the Electron Transport Chain You should indicate the reactants and products of each phase You should include the total energy products for each phase Finally, indicate where in the cell each phase occurs.
AcaCell Respiration Amusement Park Create an amusement park ride using one of the Cell Respiration processes as your inspiration. • Create an analogy for your starting material (glucose, or pyruvic acid) • Show how it will change throughout the ride • Show how energy molecules are produced (what will be the ATP released? Or NADH?) • Describe your ride, and how it relates to the CR process.
Hon Cell Respiration Amusement Park • Create an amusement park using Cell Respiration as your inspiration. • Use analogies for the starting materials, process and products of each process (like glucosemight be 6people on a ride together) Get creative!!!
