how does the human body make heat?

Question

haha im sure ima get a buncha 6th graders thinking DUH!

Answer 1

The simple answer is by burning calories.

Answer 2

ATP are like little battery packs that our cells need to function, about a 1000 of them every second... every cell (we have about 10 quadrillion cells in a normal adult body, this is of course an estimate)

It may come a bit as a surprise maybe, but our body is home of 100 quadrillion bacteria, of all kinds. They are literally everywhere. It is there endless nibbling that mainly create our body heat. Most of them are around on our planet since the down of time, 4.1 billion years ago. They chemosynthise and breathed oxygen during a billion years until oxygen reached more or less current levels.

As oxygen is poisonous to them they, some survived by finding a host in the more complex, oxygen breathing creatures forming an essential part of them (also in plants inventing photosynthesis). Much, much later they also 'found' us.

Most heat is generated in the stomach, where these (mainly) cyano bacteria break down complex molecules and provide us with simplified though energetic molecules that can be transported by the blood stream, including ATP's.

In moderate temperature zones, 50+ % of all our energy goes on heating our warm blood.

Answer 3

The second law of themodynamics say that energy cannot be changed from one form to another without a loss of usable energy. And only 39% of the free energy of glucose(a sugar) is transformed to ATP(a energy containing molecule), the rest is lost as heat. And when ATP breaks down to ADP, some energy get used and some is lost is heat too.

Answer 4

A waste product of breaking the bonds of a ATP structure is heat. This is what give us heat as well as energy.

Answer 5

biological chemical reactions

Answer 6

it is generated by the science binder
