Question
We often hear people talk about how the body “burns” glucose and other sugars to provide energy, but it’s not as simple as your stomach just creating raw energy from food. Explain how, on a cellular level, your body actually breaks down glucose and how the “energy” ends up in the inner membrane of your mitochondria.
Please make it super short and simple.

When you eat, glucose from your food enters your bloodstream and is taken up by your cells. Inside the cells, glucose undergoes a process called glycolysis, where it is broken down into pyruvate, producing a small amount of energy (ATP).
Pyruvate then moves into the mitochondria, where it's further broken down in a process called the Krebs cycle (or citric acid cycle), producing electron carriers (NADH and FADH2).
These carriers transfer electrons to the electron transport chain, located in the inner mitochondrial membrane. As the electrons move through the chain, they help pump protons across the membrane, creating a proton gradient.
Finally, protons flow back through a protein called ATP synthase, generating a large amount of ATP—the energy currency of the cell. This is how your body converts glucose into usable energy.
