Glucose Metabolism: Energy Yield
Glucose Metabolism
- GLYCOLYSIS
- Occurs in the cytosol
- Anaerobic
- Inputs: 1 Glucose
- Outputs: 2 Pyruvates, 2 ATP, 2 NADH
- PYRUVATE DECARBOXYLATION
- Occurs in the matrix
- Aerobic
- Input: 2 Pyruvates
- Outputs: 2 Acetyl CoA, 2 CO2, 2NADH
- CITRIC ACID CYCLE
Kreb's Cycle or Tricarboxylic Acid Cycle
- Occurs in the mitochondrial matrix
- Aerobic
- Input: 2 Acetyl CoA
- Output: 4CO2, 2ATP, 6NADH, 2FADH2
- OXIDATIVE PHOSPHORYLATION
- Electron transport
- Chemiosmosis
- Aerobic
- Inputs: 10 NADH, 2FADH2
- Outputs: 30-34 ATP
- Total ATP Output: 30-38 ATP
- Intertextual variation exists: exact calculations beyond the scope of this tutorial.
- Approximates yield for both eukaryotes & prokaryotes.
