The correct order is:

Glycolysis Pyruvic acid oxidation or pyruvate oxidation (produces Acetyl Co-A) Citric Acid cycle Electron Transport Chain (ETC)

Explanation:

In the cytoplasm, the process of glycolysis involves the conversion of 6-carbon glucose into two molecules of pyruvate, producing ATP and NADH as well. The two pyruvate molecules enter the mitochondrial matrix where they are converted to Acetyl Co-A by the enzyme pyruvate dehydrogenase. Acetyl Co-A enters the Kreb's cycle or citric acid cycle that generates ATP, NADH and FADH2. The NADH and FADH2 produced are converted into ATP through oxidative phosphorylation in the electron transport chain.
