What is Metabolism?

Answer 1

Like any engine your body burns energy to operate this is your metabolism.

As you exercise, then you burn more calories, and increase your metabolic rate. When you go to sleep you calm down and rest so your metabolic rate slows.

A steam engine burns coal as its fuel. The fire heats the water, which makes steam, which then powers a piston and makes the engine run.

Your body burns food, which it converts into sugar; glucose. When your muscle wants to move it contracts, muscles only do one job; they contract and they relax. So all your muscles work in pairs with other muscles. As a muscle moves it uses the body's store of sugars and oxygen to create the chemical reaction, which gives it the energy to move. Your muscles don't actually burn sugar like a fire does, but they do something similar. The waste they create includes carbon dioxide, which is then sent through the blood stream to the lungs where you exhale it. The other wastes...well you know where they go to be eliminated from the body.

This Wikipedia article explains more: http://en.wikipedia.org/wiki/Metabolism

This Wikipedia article may be a bit difficult for you: http://en.wikipedia.org/wiki/Adenosine_triphosphate
But it explains the exact chemical ATP that is used to create the reaction. The sugar and oxygen are combined with a little hydrogen and phosphorous to create ATP. ATP to an animal’s body (all animals) is like wood or coal is to a steam engine.

If you check the other Wikipedia articles listed in the ‘See Also’ section then you will get more of an idea.

Your body is a very complex organism and it takes a lot of understanding to explain metabolism. Don’t let the difficulty of the reading put you off. Even if you only understand half of it you will understand a lot.

Answer 2

Metabolism is how your body uses energy and how efficiently/ quickly energy from food can be used. If you have a high metabolism, you burn a lot of calories without a lot of physical activity. If you have a low metabolism, you burn fewer calories.

Answer 3

It's your natural weight thingy mabobber. I can't explain it but I know if you have high metabolism then you can pretty much eat whatever you want and never get fat. If you have low metabolism then you gain 10 pounds when you eat a nacho. Comprendo?

Answer 4

how fast your body burns energy

your basal metabolic rate is the rate you burn energy doing absolutly nothing

Answer 5

The simplest and most succinct answer is that it is the rate at which your body converts fuel into energy.

Answer 6

where your body burns energy look at website below (i wont copy the whole thing because you can read it from the website)
