Introduction

Mitochondrion

• double membrane
• inner membrane is highly folded to provide large sruface ara to pack more enzymes for reactions
• outer membrane is differentially permeable to control mvt of substances into and out of the mitochondrion
• intermembrane space allows rapid movment of molecules bw cytoplasm and mitochondrial matrix
• mitochondiral matrix: in inner membrane, fluid medium for reactions, enzymes

Aerobic respiration

Glycolysis

Occurs at: Cytoplasm
Does not require oxygen
\ce{glucose->[2ATP->2ADP + P] 2triose phosphate->[2NAD->2NADH; 4ADP +P->4ATP]2 pyruvate}$\ce{glucose->[2ATP->2ADP + P] 2triose phosphate->[2NAD->2NADH; 4ADP +P->4ATP]2 pyruvate}$

\ce{pyruvate->[CO2 ^; NAD->NADH; CoA]acetyl{-}CoA}$\ce{pyruvate->[CO2 ^; NAD->NADH; CoA]acetyl{-}CoA}$

Krebs cycle

Occurs at: Mitochondrial Matrix
\ce{acetyl{-}CoA + 4-C compound->[CoA ^]6-C compound}$\ce{acetyl{-}CoA + 4-C compound->[CoA ^]6-C compound}$

Oxidative phosphorylation

Occurs at: Inner membrane

\ce{NADH -> NAD + H+ +e-}$\ce{NADH -> NAD + H+ +e-}$
\ce{FADH -> FAD + H+ +e-}$\ce{FADH -> FAD + H+ +e-}$
