PHOTOSYNTHESIS CO2 + 12H2O  C6H12O6 + 6H2O + 6O2  Occurs in chlorplasts  Converts light energy to usable chemical energy  Store energy in sugar molecules  Provides organism with organic carbon  O2 is produced PHOTOPHOSPHORYLATION  light reactions  Trap light energy, convert it to chemical energy  Store it temporarily in molecules of ATP and NADPH+H+ CALVIN CYCLE  Dark reactions  Uses chemical energy stored in ATP and NADPH+H+  Reduces CO2 to sugar, which allows organism to store that energy long-term CELLULAR RESPIRATION C6H12O6 + 6H2O + 6O2  CO2+12H2O GLYCOLSIS  Occurs in cytosol  No O2 required  Breaks glucose into 2 pyruvate molecules  Energy is released o Synthesis of 2 ATP o Synthesis of 2 NADH + H+ from NAD+  Needs a supply of NAD+ and ADP to continue PYRUVATE CONVERSION TO ACETYL CoA “LINKER REACTION”  Pyruvate diffuses from cytosol to mitochondria  Carbon atoms removed from pyruvates and released as 2 CO2  Pyruvate is oxidized and 2 NAD+ is reduced to 2 NADH+H+  Coenzyme A joins with two carbon fragment from pyruvates to form 2 Acetyl CoA  Needs O2 to be present to continue KREBS CYCLE  Occurs in mitochondria  Acetyl CoA joins with oxaloacetic acid to form citric acid  Glucose is oxidized to 4 CO2 and H2O  Energy is released o Synthesis of 2 ATP o Synthesis of 6 NADH+H+ o Synthesis of 2 FADH2  Needs O2 to be present to continue ELECTRON TRANSPORT CHAIN  Occurs in mitochondria  Passes electrons from one compound to next o Oxidized then reduced  O2 is final electron acceptor  As electrons move from one compound to the next they lose energy o Energy released in small steps  1 molecule NADH+H+ contains enough energy to make 3 ATP  1 molecule FADH2 contains enough energy to make 2 ATP  Pump H+ from mitochondrial matrix to intermembrane space o H+ concentration gradient forms o H+ moves back into matrix at points of ATP synthase  NADH+H+ donates electrons to ETC and is oxidized to NAD+ to keep glycolysis and Krebs cycle going  Needs O2 to be present  28 ATP from NADH+H+  4 ATP from FADH2 TOTAL ATP YEILD 4(glycolysis and Krebs cycle) + 24(ETC) + 4(ETC) + 4(ETC) 24 ATP inside mitochondria; 2 outside mitochondria; 2 FADH2 x 2 ATP/FADH2 FERMENTATION  Occurs in cytosol  Regenerate NAD+ to keep glycolysis going so cells gain ATP when no O2 is present  Uses NADH+H+ from glycolysis to convert pyruvate to lactic acid (in animals; is converted back to pyruvate) or alcohol and CO2 (in plants; reaction is irreversible)  No ATP is produced  2 ATP from glycolysis  NAD+

"I was shooting for a perfect 4.0 GPA this semester. Having StudySoup as a study aid was critical to helping me achieve my goal...and I nailed it!"

Anthony Lee UC Santa Barbara

"I bought an awesome study guide, which helped me get an A in my Math 34B class this quarter!"

Jim McGreen Ohio University

"Knowing I can count on the Elite Notetaker in my class allows me to focus on what the professor is saying instead of just scribbling notes the whole time and falling behind."


"Their 'Elite Notetakers' are making over $1,200/month in sales by creating high quality content that helps their classmates in a time of need."
