Metabolism
Metabolism, the sum of the chemical reactions that occur within each cell of living organisms and provides energy for important processes and provides for synthesizing new organic materials.
Living creatures are unique that they can take energy from their environment and use it to fulfill activities such as movement, development and development, and reproduction. But how do living organisms, their cells, emit energy from their environment, and what cells use this energy to synthesize and collect components?
Answers to these questions lie in the enzyme-mediated chemical reactions that occur in living substances (Metabolism). Consolidated, multilevel reactions consolidated by the energy received from nutrients and / or solar energy, ultimately convert the available materials into the necessary molecules for the development and maintenance.
The physical and chemical properties of the components of the living things dealt with in this article are found in the carbohydrate; Cell; Hormones; Lipid; Photosynthesis; And protein.
A Balancing Act
The process of Metabolism is actually a balanced function that involves two types of activities that run at the same time – by building more body tissues and energy stores and breaking body tissues and energy stores, more fuel for the body’s functions Is generated:
Anabolism is all about the development of new cells, maintenance of body tissues, and energy storage for future use. Supports During anabolism, small molecules are converted into more complex, more complex molecules of carbohydrate, proteins and fats.
Catabolism (pronounced: kuh-TAB-uh-lih-zem), or Destructive Metabolism, is the process that generates the energy necessary for all activities in cells. In this process, cells break large molecules (mostly carbohydrate and fat) to free energy. This energy release provides fuel for anabolism, heats the body, and enables the muscles to contract and move the body. Since complex chemical units are divided into more simple substances, the waste products released in the process of synthesis are removed from the body through the skin, kidneys, lungs and intestines.
Many hormones of the endocrine system are involved in controlling the rate and direction of metabolism. Thyroxine (pronounced: thigh-ROK-seen), a hormone produced by the thyroid (released: thigh-royd) plays an important role in determining how rapid or slow the chemical reactions of metabolism are, Moves forward in the body.

Another gland, pancreas (pronounced: PAN-kree-us) secretes (gives off) that helps determine whether the body’s main metabolic activity at any particular time will be anabolic or synthetic or not. For example, after eating meals, there is usually more anabolic activity because blood glucose levels increase – the most important fuel in the body – in the blood. Pancreatic feels this growing level of glucose and releases hormone insulin (pronounced: IN-suh-lin), which prompts cells to increase their anabolic activity.
Metabolism is a complex chemical process, so it is not surprising that many people think it in its simplest way: something that affects how easily our bodies lose weight or lose weight. This is where calories come in. A calorie is a unit that measures how much energy the body gives to a particular food. A chocolate bar contains more calories than an apple, so it provides more energy to the body – and sometimes it can be a good thing. As soon as the car stores gas in the gas tank, unless the engine is fueled, the body stores calories – mainly as fat. If you fill the gas tank of the car, it spreads on the sidewalk. Similarly, if a person eats too much calories, then he “spreads” on the body as extra fat.
The number of calories burned in a day, how many exercises this person has, is influenced by the amount of fat and muscle in its body, and the basic metabolic rate (BMR) of the person. BMR is the rate at which the body “burns” energy in the form of calories, on the rest BMR can play a role in a person’s tendency to increase weight. For example, a person with lower BMR (which burns less calories while relaxing or sleeping) receives more pounds of body fat over time compared to the person having the same size, which occurs with the average BMR which is the same amount Eats food in and receives the same amount of exercise.
