Answer 1

We don’t actually burn them. Essentially, all of your cells need nutrients to survive, and they need to convert the chemical energy in food into energy they can use for their specific purposes.

So broadly speaking, you ingest food, the acids in your stomach break the food down, the cells in your small intestine absorb nutrients and water from the food, and your blood carries those nutrients around to all of your cells.

Inside each cell there’s a process that happens called cellular metabolism, which is a pretty complex series of chemical reactions. Those chemical reactions produce energy for each of your cells to use.
