Cellular Respiration

Precess through which the body synthesizes energy in the form of ATP.

Glycolysis

The process of breaking a 6 carbon glucose molecule down, creating two 3 carbon pyruvate molecules.

Investment

2 ATP + 1 Glucose

Payoff

2 NADH + 4 ATP

2 Pyruvate

Aerobic

Occurs in Cytoplasm

Anaerobic

Alcohol or Lactic Acid Fermentation

Liver

Oxidized into Pyruvate

Pyruvate Oxidation

Step1: Carboxyl group removed

Released as 1 CO2 per pyruvate

Step 2: Oxidized

Step 3: Acetyl group transfered to coenzyme A

2 Acetyl CoA

Krebs Cycle

Occurs in mitochondrial Matrix

2 acetyl CoA enter for every glucose molecule

Oxaloacetate

Oxaloacetate is the starting and ending molecule of krebs cycle, and the reason that it can repeat.

Citric Acid

Loses carbons as CO2

REDOX Reaction

NADH and FADH2 carry hydrogen

Spins Twice

2 CO2+ 3 NADH + 1 FADH2 +1 ATP produced for each spin

NADH, FADH2

Releases waste CO2

Electron Transport Chain

Complex I

AKA NADH Dehydrogenasedrop off point for NADH electron shuttles

NADH

8 Protons pumped out

Drop off point for FADH2 shuttlesbrings these electrons, as well as the ones from complex I, to complex II

Complex II

AKA Cytochrome b-c complexFrom here, electrons will go to cyt-C

FADH2

12 Protons pumped out

Complex III

Cytochrome Oxidase ComplexLast complex before electrons go to oxygen

12 Protons pumped out

C shuttles electrons to the third complex

Oxygen

Most electronegativecombines with electrons and protons to make waterwater needed to establish the concentration gradient

Water

End of electron transport chain

Occurs across inner mitochondrial membrane

Chemiosmosis

Complex IV

More commonly known as ATP synthaseonly channel through which the banished protons can get back into the matrix after a concentration gradient has been establisheduses kinetic energy from incoming protons to "charge" ATPEnergy is used to bond ADP and P

Mitochondria

Intermembrane Space

Concentration Gradient
