Is mitochondria an organelle that burns a cell's food for energy?

Kind of. But it does a lot more than burn it. If we just burnt food we would get a big release of energy instantly.

Instead mitochondria produce a chemical called ATP which we use for energy. Each molecule of glucose you eat produces 36 molecules of ATP.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
