The electron transport system occurs in the mitochondria and follows the citric acid cycle. This is the final stage of cellular respiration where the majority of ATP is produced. Here's a step-by-step breakdown:

1. Glycolysis: This is the first step of cellular respiration and it occurs in the cytoplasm. One molecule of glucose is broken down into two molecules of pyruvate. This process produces a small amount of ATP and NADH.

2. Citric Acid Cycle (also known as Krebs Cycle or TCA Cycle): This occurs in the mitochondria. The pyruvate from glycolysis is further broken down and this process produces ATP, NADH, and FADH2.

3. Electron Transport Chain (ETC): This is the final stage and it also occurs in the mitochondria. The NADH and FADH2 produced in the previous steps are used here to produce the majority of the cell's ATP. The electrons from NADH and FADH2 are transferred through a series of proteins (the electron transport chain) in the inner mitochondrial membrane. This process of transferring electrons creates a flow of protons across the membrane, creating a gradient. This gradient is used to produce ATP.

So, the electron transport system occurs in the mitochondria and follows the citric acid cycle.
