Hello, As you can tell I'm new here. I'm not into science generally but I have come across some discussions online that have gained my interest. So I would like to get a basic understanding of a few things that I don't understand. So my question is, do cells generate heat? And I what I mean is does a human's cell actually heat to burn food and turn it into energy? From what I've read so far is that a cell will change the food molecules through a chemical reaction into a energy that the body can use. Does this process involve or produce heat in anyway? And I'll apologize in advance if I'm coming off as a idiot. I am a science and biology newbie but I'm curious to learn more. Thanks!
