I am vaguely aware that the food we eat constitutes a sort of fuel that can be thought of as "calories" for comparative purposes, but I don't really have any idea how the body takes this fuel and harvests energy from it.
A certain amount of the calories we eat have to go to maintaining body temperature but the food obviously isn't combusted in any conventional sense. So, one thing I'm wondering where the heat actually comes from.
The other is how food is turned to muscle contractions that allow us to move ourselves and other things.
