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.

According to the National Institute on Drug Abuse, anabolic steroids are synthetic variations of the male sex hormone testosterone. The article claims that healthcare providers can prescribe steroids for treating hormonal problems, such as late puberty. Also, steroids can also treat diseases that cause muscle losses, such as cancer and AIDS. But some athletes and bodybuilders abuse these drugs to increase performance or improve their physical appearance.

• 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).

The most commonly used steroids are anabolic steroids, which create growth in the skeletal muscle, hence are being used by bodybuilders, weight lifters and even sporting athletes. They help the body's cells in the muscle produce protein which ultimately leads greater strength and size, and at the same time helps produce fuel the muscles need to keep going for longer.

They are also referred to as anabolic, which is used to promote growth in muscle, specifically skeletal muscle, and androgenic, which is the development of male sexual characteristics in males and females. Testosterone is the male sex hormone responsible for developmental changes during puberty, in males. They also hold an androgenic effect, which again is primary/secondary sexual characteristic changes, such as, voice changes, hair growth, genital changes and emotional effects. Testosterone also has an anabolic effect such as muscle, bone, and red blood cell growth. The way anabolic steroids work is by affecting the activation rate of the enzymes involved in protein metabolism. This is used to enhance protein synthesis and decrease the degrading of protein in the muscle, which is called an anti-catabolic

    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.

Insulin is a hormone which is produced and distributed into the bloodstream by beta cells located in the pancreas. The main function of insulin is to lower the level of glucose in the blood by:

Androgenic-anabolic steroids (AAS) are synthetic derivatives of the male hormone testosterone. Testosterone is produced in the Leydig cells of the testes. Scientist have tried to reproduce a synthetic form of this hormone since the early 1900s. As early as 1935, the production of synthetic hormones has been possible. These hormones have two distinct effects. The androgenic effects which produce the development of the male characteristics such as hair and beard growth, deepened voice, and increased strength. The anabolic effects cause protein synthesis and inhibit the breakdown of proteins. This leads to increased muscle size, strength, and quicker recovery with proper workout routines. The primary medical uses of these compounds are to treat delayed puberty, some types of impotence, and wasting of the body caused by HIV infection or other diseases.

According to studies, hormones play a vital role in human’s mind and body. Endocrine is just one of many systems present in our body which is responsible in maintaining the balance state of mind and body. One specific hormone produce by this gland is testosterone that falls under the family of androgen. Get a supplement that can boost your testosterone from credible

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.

Hormones are compounds produced by the endocrine system that chemically regulate specific body functions. Steroid hormones have a biochemical unique 4-ring structure, including three 6-carbon rings and one 5-carbon ring. Androgens are steroids hormones synthesized primarily in the gonads and adrenal glands. Testosterone, the key androgen, affects sexual features and development. It maintains nitrogen balance and facilitates protein synthesis (anabolism). In men, it is made in large amounts by the Leydig cells of the testes and in women, by the ovaries. The pituitary gland in the brain secretes hormones called luteinizing hormones (LH) and follicle stimulating hormone (FSH) which regulate the number of Leydig cells in the testes. Also, LH controls how much testosterone the Leydig cells produce by regulating the expression of 17-b hydroxysteroid dehydrogenase. Since this enzyme mediates the rate-limiting step of testosterone synthesis, its inhibition can stop the synthesis of. Males synthesize 2.5 to 11mg of Testosterone a day while females produce about 0.25 mg daily.
