Cellular Respiration:

General Formula

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

Glycolysis = 2 ATP_net + 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
