Metabolism Essay

Metabolism is the sum of all chemical reactions that take place in the body and how fast the body utilizes the calories that we put into it. Body weight increases and decreases based on the amount of calories put in and the amount of energy we burn.

b) Janine made this statement: “… if your brain doesn’t get carbs—well, glucose, anyway—you get

Metabolism is a chemical process that converts fuel from food into energy needed for the body’s activities. For example, thinking, running and jumping etc. are all an example of the bodies activities.

• Enzymes are involved in processes such as the breakdown of carbohydrates and converts them into energy for the body to use.

Insulin: Hormone secreted by the pancreas and required by body cells for the uptake and storage of glucose (Health The Basics, Chapter 12, pg412).

a family of hormones that include the natural male hormone testosterone… These hormones have anabolic (“muscle building”) and androgenic (“masculinizing”) effects, resulting in increased muscle strength and athletic performance, at times beyond what could be attained naturally (7).

    Anabolic-androgenic steroids are a group of hormones, which includes the natural male hormone, testosterone, and a number of synthetic compounds. "Anabolic" refers to muscle building, while "androgenic" refers to increased masculine characteristics. Anabolic effects are basically muscle growth. Androgenic effects produce secondary male sex characteristics like facial hair, body hair, deepening of the voice, and so on. In the 1950's scientists were trying to isolate the muscle building properties without the masculinizing effects. This lead to the development of synthetic anabolic steroids.

Cellular metabolism is the cells daily operation through all types of reactions in the cell. These reactions are rated at several different speeds and occurrences according to the cells needs. However, there are some occasions where the articulation of these cells can become faulty and eventually destroy the body. A particular homeostatic imbalance that occurs from a fault in the cellular metabolism and metabolic pathways would be the body 's resistance to produce insulin. A more formal name for this imbalance would be diabetes. Although there are several types of diabetes they all result in an insufficient amount of insulin production in the beta cells of the body.

In this paper, I will be discussing metabolism and the major role it plays in the human body. A general definition of metabolism would be all the chemical reactions that take place in an organism. Humans metabolize sugars and lipids differently. Lipids are fats and the enzyme lipase can break through the fat bonds once it enters the small intestine. The liver produces bile which binds to broken fat pieces so they can be absorbed into the bloodstream. Carbohydrates and sugars start their breakdown as soon as they enter the mouth, where amylase in the saliva, starts the breakdown process. It continues to break down in the stomach and is completed in the small intestines. Sugars, however, continue to breakdown until they are tiny monosaccharides

These are lipids (fat-soluble chemicals) produced naturally by the human body. Some of these steroids include the male hormone testosterone (an androgen) and the female hormones estrogen and progesterone. Testosterone is responsible for many of the physical changes that occur to males during adolescence, such as deepening of the voice and increase in muscle mass. Even after adolescence, testosterone continues to influence a variety of male sexual and emotional processes.

Testosterone is a hormone required for male development and sexual function. It is also responsible for building muscle mass, sperm production, and sex drive. Testosterone also influences male pattern fat distribution, bone density, and red blood cell production. The normal developing male peaks at his testosterone level during early adulthood. Once he has reached the age of 30, testosterone decease at approximately 1% per year.

When testosterone levels are high, you are able to grow muscle tissue at a faster pace.

HGH, a polypeptide made up of 191 amino acids, is naturally produced commonly every night when you are asleep. It is created by a kidney-bean-size gland at the base of your brain called the pituitary gland. Human growth hormone circulates throughout your bloodstream and attaches to specific cell-surface receptors throughout the body, including the brain. Those receptors are dense in the parts responsible for learning and memory. Human growth hormone plays a major role in maintaining the health of all human tissue, including other vital organs besides the brain. It is proven to bind to fat cells, causing them to release part of their load, and stimulate the liver to create a powerful hormone called IGF-1 which helps the growth of muscle, cartilage, and bone.

Growth hormone, also called human growth hormone, is a naturally occurring substance that is made by your pituitary gland and then released into the bloodstream. The pituitary gland is a small organ that is located in the center of your brain and makes hormones. Growth hormone is essential for normal growth and development in children. Growth hormone also helps regulate metabolism in both children and adults.

When men take steroid hormones such as testosterone to boost their performance, it can shrivel their testicles and make their breasts grow. For women, it can give a deeper voice, clitoris enlargement, hair loss, and facial hair growth.
