How does the food we chew and swallow fuel our cells?

The food we chew and swallow is broken down through digestion into smaller molecules, primarily carbohydrates, proteins, and fats. These molecules are then absorbed into the bloodstream and transported to our cells. Inside the cells, they undergo metabolic processes, such as cellular respiration, where they are converted into energy in the form of adenosine triphosphate (ATP). This energy fuels various cellular functions, enabling growth, repair, and maintenance of bodily processes.
