Understanding Metabolism

Most people know the basics of metabolism-the faster it is the more fat you burn. But how does metabolism work? Our bodies get the energy that they need from the food that we eat and we need energy to survive. The most basic bodily functions and simple movements require some source of energy. Even thinking requires energy. Metabolism is a constant process which begins when we are conceived and does not end until we pass away. If our metabolism ceases to exist than so do we.

Metabolism starts with consumption. As soon as you eat food the molecules in the digestive system start to break it down. The body then breaks it down further so that the energy released can be used as fuel by, the bodys cells. Next the enzymes break proteins down into amino acids, fats into fatty acids, and carbohydrates into simple sugars. Sugar, amino acids, and fatty acids are all used as energy by the body when needed. The blood is actually the storage house for these compounds and it transports them to the cells as needed. After they enter the cells, other enzymes speed up or regulate the chemical reactions involved which metabolizes these compounds. At this point the energy is actually useful energy. The body can use it or store it in body tissues or organs. The endocrine system also plays a big role in metabolism. A hormone called Thyroxine is produced and released by the thyroid gland. This is what regulates the speed of your metabolism.

Although you may think of metabolism only as something that is to be blamed for a few extra unnecessary pounds, metabolism actually has a big role in our everyday life aside from influencing our weight . Metabolism allows us to grow, reproduce, maintain our structures, and respond to our environment.
