The correct pathway of electrons in aerobic respiration is: glucose → glycolysis → Krebs cycle → electron transport chain → oxygen.

However, from the options given, the closest one is: glucose → glycolysis → Krebs cycle → FADH2 → ATP.

Here's a step-by-step breakdown:

1. Glucose: This is the starting point. It's a type of sugar that our bodies use for energy.

2. Glycolysis: This is the process where glucose is broken down into a molecule called pyruvate. This process also produces 2 ATP molecules and 2 NADH molecules.

3. Krebs Cycle (also known as the Citric Acid Cycle): This is where pyruvate is further broken down and electrons are transferred to carrier molecules NAD+ and FAD, forming NADH and FADH2.

4. Electron Transport Chain: This is where most of the ATP is produced. The electrons from NADH and FADH2 are passed along a series of proteins, and this energy is used to pump protons across a membrane, creating a gradient. This gradient is then used to produce ATP.

5. Oxygen: This is the final electron acceptor in the electron transport chain. It combines with electrons and protons to form water.

Please note that ATP is produced in the process, but it's not part of the electron pathway.
