Many people are in quarrel on whether steroids should be legal or not pertaining to sports. While some say steroids offer a great new excitement into the sports culture, others say it is a way of cheating and allows an unfair advantage to the game. Although steroids may offer a slight boost in performance, they shouldn’t be allowed. The reason being is because it gives an unfair advantage in playing the game and it also encourages a vicious arms race. The use of steroids can cause an excessive…

The various organ systems of the human body work together to maintain homeostasis. Typically, when someone hears the words organ system the first one that comes to mind is the circulatory system. The circulatory system is responsible for transporting oxygen and nutrients in the blood to nearby cells as well as helping with the removal of waste products and carrying them away in plasma. The reproductive system maintains homeostasis by regulating the Ph of the vagina in the female reproductive…

Anabolic steroids were not always illegal drugs. In the 1960s and early 1970s bodybuilders and Olympic weightlifters legally received steroids from a pharmacy. However, in 1975 the International Olympic Committee officially banned the use of anabolic steroids in Olympic competitions (Anabolic). Although Olympians no longer legally took the drugs, black market sales skyrocketed in the following years (Anabolic). In 1988, the first major federal regulation of steroids was put into practice as part…

. SIRT1 is one of the many vital genes that is highly controlled during caloric restriction, which leads to a number of biological variations to extend lifespan. Resveratrol’s activation of the SIRT1 gene affects a number of cellular processes. Resveratrol decreases nuclear factor kappa B (NFκB) activation.The nuclear factor kappa B is located in the cellular cytoplasm and moves to the nucleus upon activation where it stimulates transcription of multiple pro- inflammatory genes such as TNFα,…

Photosynthesis and Cellular Respiration is just like a bee and flower. As a bee pollinates a flower, the flower gives the bee nectar. Photosynthesis gives Cellular Respiration sugar and oxygen and Cellular Respiration gives carbon dioxide and water to Photosynthesis. The making of food using the sun's energy is called Photosynthesis. Photosynthesis occurs in the organism called Chloroplast. There is a green pigment inside the Chloroplast called Chlorophyll which absorbs light from the sun. Then…

Side effects of Whey Protein Sufficiently devouring protein is one of the necessities to assemble muscle, yet consuming a lot of it can build up a percentage of the known whey protein side effects. A typical individual has a necessity of something like 0.5 grams of protein per pound of his or her body weight. A man that is attempting to construct muscle requires all the more, around 1g every pound. Proficient jocks can take even 2 g every pound. Taking whey protein supplements can help you…

Cells in the human body require many compounds to survive. The main substances found in all living organisms are a mix of carbohydrates, lipids, proteins and nucleic acids. Each of these substances has a different niche as a part of the body, and all of them must either come from the diet or be created using other chemicals in the body. Functions of Carbs Carbohydrates are the preferred source of energy for most of the tissues in the body, including the nervous system and the heart.…

Prokaryotes, specifically bacteria, have feedback regulatory mechanisms like eukaryotes do to make tryptophan. Tryptophan is one of the 20 amino acids which we all need. If there is a lot of tryptophan made, then you turn off the enzymes that are involved in tryptophan synthesis by binding and causing a change in shape of the enzyme (negative feedback). In addition, repressors are proteins that bind to the operator and prevents expression of the gene. However, the repressor is unable to bind to…

Describe, briefly two cellular reactions that involve ATP hydrolysis (you will probably find the answer more quickly on Google than in your book). ATP is simply a renewable resource which is actually rejuvenated when adenosine diphosphate is mixed with a phosphate group. On the other hand, ATP hydrolysis is basically a method used by the human body to be able to release energy chemically to some other body parts in order for life to be sustained. In the process, ATP is actually converted…
