Here are the essential concepts you must grasp in order to answer the question correctly.
Glycolysis
Glycolysis is the metabolic pathway that converts glucose into pyruvate, producing a small amount of ATP and NADH in the process. It occurs in the cytoplasm and is the first step in cellular respiration, setting the stage for further energy extraction from glucose.

Citric Acid Cycle
The Citric Acid Cycle, also known as the Krebs cycle, is a series of chemical reactions that take place in the mitochondria. It processes acetyl-CoA derived from pyruvate, generating high-energy electron carriers (NADH and FADH2) and releasing carbon dioxide, which is crucial for energy production.

Electron Transport Chain
The Electron Transport Chain (ETC) is a series of protein complexes located in the inner mitochondrial membrane. It utilizes the high-energy electrons from NADH and FADH2 to create a proton gradient, ultimately leading to the production of ATP through oxidative phosphorylation, where most of the energy from glucose is stored.
