Cellular Respiration The process that releases energy (ATP) by breaking down food molecules in the presence of oxygen
Mitochondria Found? Plant & Animal Cells Where respiration takes place Just aerobic parts
Aerobic Vs. Anaerobic Respiration Aerobic = presence of O 2 Respiration Anaerobic = absence of O 2 Fermentation
Pathway of Cellular Respiration Glycolysis (Cytoplasm) Krebs Cycle (Mito.) Electron Transport Chain (Mito.)
Glycolysis “Glukus” = sweet “Lysis” = loosening Occurs in Cytoplasm Breaking one glucose down into 2 pyruvic acids(3 Carbon) & 2 ATP (net)
After Glycolysis Anaerobic = Fermentation Aerobic = Cellular Respiration
Fermentation Fermentation will make energy without O 2 Two types Alcoholic Lactic acid
Alcoholic Yeast & other microorganisms CO 2 causes bread to rise
Lactic Acid Animal muscles Happens during vigorous exercise Builds up in muscles causing cramps
Krebs Cycle Follows glycolysis Needs oxygen Respiration Occurs in mitochondria Breaks down products of glycolysis into carbon dioxide Releasing energy to make electron carriers and ATP
Electron Transport Chain Inner membrane of mitochondria Electrons move to produce energy
ETC: Makes ATP – 2-3 per electron carrier Oxygen is used as the final electron acceptor (H+) Forms water
Mitochondrial membrane NADH NADH enters and releases an H+ and an electron.
Mitochondrial membrane NADH enters and releases an H+ and an electron. e- NAD+
Mitochondrial membrane The electron travels to the next protein while simultaneously sending H+ across the membrane e- H+ O
Mitochondrial membrane The electron is used to form water. The H+ then are pumped back into the mitochondria. H+ H2O ADP P
Mitochondrial membrane This allows ATP to be made each time a H+ enters back in. H+ ATP
Totals Glycolysis Net 2 ATP Krebs 2 ATP ETC Electron carriers = 32 ATP **Total = 36 ATP
Photosynthesis Vs Cellular Respiration

Cellular Respiration Breaking down food to get energy.
Warm Up Answer the following questions in your notebook. Be sure to include the question as well. How many ATP are produced in total through cellular.
ATP and Cellular Respiration
CELLULAR RESPIRATION. WHO DOES CELLULAR RESPIRATION? Animals Humans Plants/Algae Basically any organism with nuclei & mitochondria So what other organisms.
