Name:____________________             Weeks 4-5 Material BIO201C       TA: Sarah Ventre, Email: sjventre@buffalo.edu Mitochondria:  Structure:  large organelles with outer porous membrane and highly impermeable inner  membrane made of folds called cristae .   o Porins     - integral proteins within the outer porous membrane. o Cristae     - where electron transport and ATP formation occurs. o Matrix     - gel-like interior surrounded by the cristae; contains proteins, DNA, RNA,  and ribosomes. Function:   oxidative metabolism in cell to convert macromolecules into chemical  energy. o Glycolysis     - takes place in the cytosol. Net reaction      Glucose + 2 NAD +2ADP + 2P i    2 Pyruvate + 2ATP + 2NADH + 2H + 2H 2 O o Pyruvate is transported across inner mito. membrane and combines with  coenzyme A to form acetyl CoA    condensed with oxaloacetate to form citrate. o TCA Cycle (Kreb’s Cycle)-      takes place in the mito. matrix.  Net reactions =      Acetyl CoA + 2H 2 O + GDP + FAD + 3NAD + + 2P i                2CO 2  + FADH 2  +3NADH + 3H +  + GTP + HS—CoA  o Electron Transport Chain (or Oxidative Phosphorylation     - takes place in inner  mito. membrane containing various carriers arranged in order of increasingly  positive redox potential
