Here's a simplified breakdown:
* Food molecules (like glucose) are broken down into smaller molecules. This happens in a series of steps, starting with glycolysis.
* Oxygen is used to further break down these smaller molecules. This occurs in the mitochondria, the powerhouse of the cell.
* Energy is released in the form of ATP (adenosine triphosphate). ATP is the primary energy currency of cells, and it's used to power various cellular processes.
Cellular respiration is a complex process with several stages, but the key takeaway is that it's how your body converts the energy stored in food into a usable form for all your bodily functions.
