Cellular Respiration:

General Formula

For aerobic respiration (in the presence of O2)
C6H12O6 + 6O2 --> 6H2O + 6CO2 + 36ATP (theoretical)
                                                                  30ATP (actual)


Glycolysis = 2 ATPnet + 2 FADH2 (4 ATP actual = 3) è 6 ATP actual = 5
Pyruvate Oxidation = 2 NADH (6 ATP actual = 5) è 6 ATP actual = 5
Kreb's Cycle
= 2 ATP + 6 NADH (18 ATP actual = 15) + 2 FADH2 (4 ATP actual = 3) è 24 ATP actual = 20

Mitochondria

  • A sausage shaped organelle in eukaryotic cells and is membrane bound
  • Last 3 steps of cell. resp. take place here
  • Inner membrane -> highly folded -> cristae
  • Fluid filled interior -> matrix
  • Have their own DNA (mtDNA) and own RNA and ribosomes
    • Only organelle (along with chloroplast) that can replicate itself
  • Were once a separate organism but entered symbiotic relationship with a present eukaryotic cell
