Glycolysis Acetyl-CoA production Krebs cycle Electron transport chain

Solution

1. Glycolyis: Phosphorylation of glucose and fructose 6-phosphate uses two ATP from the cytoplasm.

2. Krebs cycle and Acetyl CoA production.

Acetyl CoA production: Pyruvic acid + CoA + NAD⁺ ---> Acetyl CoA + NADH + H⁺ + CO₂

Krebs Cycle: C₆H₁₂O₆ + 6 O₂ 6 CO₂ + 6 H₂O

3. Krebs cycle is also called the citric acid cycle.

4. Glycolysis

5. Electron transport chain acts as the proton pumps.
