Metabolism is a collection of chemic substance re kneadions that sign ups place in the forms cells. Metabolism changes the dismiss in the food for thought we eat into the energy needed to power everything we do, from moving, thinking and growing. unique(predicate) proteins in the remains control the chemical reactions of metabolism, and each chemical reaction is matched with other body functions. There are many another(prenominal) metabolic reactions happen at the same time, they are all(prenominal) regulated by the body to keep every individuals cells honorable and working.
For example, an example of how the shape of metabolism works in globe â€" and it begins with seed downs. Firstly, a green plant takes in energy from sunlight. The plant uses this energy and a molecule called chlorophyll (which gives plants their green color) to strain sugars from water and carbon dioxide. This process is called photosynthesis.
When people and animals eat the plants, they take in this energy (in the form of sugar), along with other bouncy cell-building chemicals. The bodys next step is to cease the sugar down so that the energy released rump be distributed to, and used as fuel by, the bodys cells.
After food is eaten, molecules in the digestive system called enzymes break proteins down into amino acids, fats into fatty acids, and carbohydrates into simple sugars such as glucose. In addition to sugar, both amino acids and fatty acids can be used as energy sources by the body when needed. These compounds are absorbed into the blood, which transports them to the cells. After they enter the cells, other enzymes act to speed up or regulate the chemical reactions gnarled with metabolizing these compounds. During these processes, the energy from these compounds can be released for use by the body or stored in body tissues, especially the liver, muscles, and body fat.
The process of metabolism is a balancing act involving two kinds of activities that go on at the same time â€" the building up of body tissues and energy stores and the...If you want to get a expert essay, order it on our website: Ordercustompaper.com
