Study Notes
Aerobic Respiration Components
- Aerobic respiration consists of three components: glycolysis, the Krebs cycle, and oxidative phosphorylation.
Glycolysis
- Glycolysis generates energy in the form of ATP from sugars.
- Occurs in the cytosol and splits glucose into two pyruvate molecules.
- Produces 2 ATP and 2 NADH as byproducts.
Krebs Cycle
- Pyruvate is converted to acetyl-CoA and enters the Krebs cycle in the mitochondrial matrix.
- Produces ATP, NADH, and FADH2 from acetyl-CoA.
Oxidative Phosphorylation
- Oxygen is directly consumed to generate ATP as the final component of aerobic respiration.
- NADH and FADH2 drive the electron transport chain to produce more ATP.
Aerobic Respiration Components
- Three components of aerobic respiration: glycolysis, the Krebs cycle, and oxidative phosphorylation.
Glycolysis
- Occurs in the cytosol.
- Breaks down glucose into two pyruvate molecules.
- Generates 2 ATP and 2 NADH.
The Krebs Cycle
- Occurs in the mitochondrial matrix.
- Converts pyruvate into acetyl-CoA.
- Produces ATP, NADH, and FADH2 from acetyl-CoA.
Functions of Krebs Cycle Products
- NADH and FADH2 drive the electron transport chain.
- Electron transport chain produces more ATP.
Oxidative Phosphorylation
- Only directly consumes O2 to generate ATP.
- Final component of aerobic respiration.
