Biohem Both plant and animal cells carry out the final stage of cellular respiration It takes place in the mitochondria One gram of sugar glucose (C6 H12 C6) release 3811 calories of energy/calories is the amount of energy needed to raise the temp cell Cells don't “ burn “ glucose instead they release from glucose and other compounds The process starts with glucose is which releases a small amount of energy If oxygen isn't present glycolysis followed by the krebs cycle and electron transport cycle This makes up cellular respiration Insert pi of mitochondria NOTE Cellular Respiration is the process that releases energy by breaking down food with the presence of oxygen EQUATION Co2+ C6H12C6 ->6Co2+6H2O+Energy Oxygen + glucose -> carbon dioxide +water +ENERGY Glycolysis is the process in which one molecule of glucose is broken in half producing two molecules of pyruvic acid a 3 carbon compound Not require oxygen ATP PRODUCTION At the beginning of glycolysis the cell uses up 2 molecules atp to start the reaction NADH production One reaction of glycolysis remains 4 high energy electrons passing them to an electron carrier called NAD+ AEROBIC FERMENTATION Pyruvic acid +NADH-> ALCOHOL + Co2+NAD. lactic acid +NAD LACTIC acid fermentation pyruvic acid +NADH -> NAD+ Oxygen required - aerobic Oxygen not required - anaerobic 1. Glycolysis produces 2 atp molecules per glucose Photosenthesis Chloroplasts contain thylakoids - sack like  A stack of thylakoids is geranium - The thylakoids membrane organize chlorophyll and other pigment into clusters called photosystems Reactions- light dependant -takes place within thylakoids membrane -produce- oxygen - converts - adp and nadp+ -to- atp and nadph Light independent reactions ( calvin cycle) Takes place in the stroma (the region outside the thylakoid) Uses atp and nadph to build high energy compounds/sugars Factors affecting the rate photosynthesis -water Temperature Light intensity
