Cellular Respiration

Process that releases energy by breaking down glucose and other food molecules using oxygen Process that releases energy by breaking down glucose and other food molecules using oxygen Happens here = mitochondria Happens here = mitochondria

Occurs in these types of cells

Plant CellAnimal Cell Mitocho ndria

Outer membrane Inner membrane Intermembrane space Matrix Folds are called ….. cristae

Cellular Respiration… 3 main stages Glycolysis Krebs Cycle ETC

aerob ic anaer obic w/ oxygen w/o oxygen All 3 steps Step 1 plus detour fermentation Alcoholic fermentation Lactic Acid fermentation

Parts of Cellular Respiration If Oxygen = Aerobic If Oxygen = Aerobic 1) Glycolysis – in cytoplasm – 2 ATP 1) Glycolysis – in cytoplasm – 2 ATP 2) Krebs Cycle – in mito – 2 ATP 2) Krebs Cycle – in mito – 2 ATP 3) Electron Transport – in mito – 32 ATP 3) Electron Transport – in mito – 32 ATP If NO Oxygen = Anaerobic If NO Oxygen = Anaerobic 1) Glycolysis – in cytoplasm – 2 ATP 1) Glycolysis – in cytoplasm – 2 ATP 2) Fermentation – in mito – 2 ATP 2) Fermentation – in mito – 2 ATP Alcoholic – yeast Alcoholic – yeast Lactic Acid - us Lactic Acid - us

Picture time… woohoo Get out your markers… Get out your markers…
