Question

Bio Ch 3 Describe the 11 steps of the aerobic Pathway.

Answer 1

The 11 steps of the aerobic pathway include glycolysis, pyruvate oxidation, the citric acid cycle, oxidative phosphorylation, the electron transport chain, ATP synthesis, and chemiosmosis.

Step-by-step explanation:

11 Steps of the Aerobic Pathway:

1. Glycolysis: Glucose is broken down into two molecules of pyruvate
2. Pyruvate Oxidation: Each pyruvate is converted into Acetyl CoA
3. Citric Acid Cycle: Acetyl CoA enters a cycle of reactions to produce energy
4. Oxidative Phosphorylation: The energy produced in previous steps is used to generate ATP

The remaining steps involve the Electron Transport Chain:

1. Electron Transport Chain: Electrons from NADH and FADH2 are passed along a series of protein complexes
2. Complex I: Electrons enter the chain and transfer energy
3. Complex II: Further energy transfer occurs
4. Complex III: Electrons are transported
5. Complex IV: Electrons combine with molecular oxygen to produce water

The final steps are:

1. ATP Synthesis: ATP is synthesized using ATP synthase and the energy from the electron transport chain
2. Chemiosmosis: A chemiosmotic gradient is created across a membrane, which drives ATP synthesis
