more selective. To guarantee that only the correct molecules get to the matrix, the inner membrane uses transport proteins. Mitochondria’s role within the cell is to perform aerobic respiration (respiration in the presence of oxygen) to create ATP (adenosine 5′‐triphosphate) which is then transported around the cell to be used as chemical energy. The enzyme used to make the ATP is housed within the inner membrane which is why the convoluted shape is necessary. This shape maximises the surface…

Under oxidative conditions, certain nucleobases (for example, adenine and cytosine) can form N-oxides. Also, the C8 position of guanosine is vulnerable to hydrolytic attack under either strongly acidic or strongly alkaline conditions. The 5,6 double bond of pyrimidine nucleosides also reacts with halogens and halohydrins to give the corresponding addition products (Shabarova and Bogdanov, 1994). Selected examples of the side reactions that occur during oligonucleotide synthesis are given below.…

Introduction The purpose of this research study is to determine the effects of a high intensity versus a low intensity warm up on oxygen deficit and performance. This study hypothesized that the oxygen deficit levels will decrease with a high intensity warm up, therefore reaching steady state faster compared to a low intensity warm up. The Independent Variables are high intensity warm up versus a low intensity warm up, and the Dependent Variable are Oxygen Deficit and performance. There are…

Transcription in prokaryotes requires the formation of the holoenzyme RNA polymerase (holoRNAP), which consists of a core enzyme and a σ subunit. The core enzyme consists of 5 subunits: 2 copies of α, which assemble the enzyme and bind regulatory factors; one copy of β, which has polymerase activity of RNA chain initiation and elongation; one copy of β’, which binds nonspecifically to DNA; and omega. An active center where RNA synthesis occurs is located within the DNA binding channel formed by…

Introduction: The purpose of this study is to determine if obesity in pregnant women leads to higher rates of obesity in their offspring. According to the World Health Organization, obesity should be treated as a world wide epidemic ( WHO). One in three Americans are obese and many more are overweight, or on the borderline of obesity. Public opinion of obesity has always been that is is simply due to lifestyle choices or poor diet and exercise; however, the World Health Organization believes…

and not necessarily to a surge of occurrences in all age groups (Gillespie, 2006). Glucose. As the main source of energy for many of the tissues in the body, glucose holds much importance. It is metabolized during cellular respiration to release adenosine triphosphate (ATP), which is necessary to carry out many bodily functions (Leslie, 2013). The homeostasis of glucose is maintained by the hormones glucagon, and insulin. It is urgent that the homeostasis of glucose be maintained in order to…

are another form of vesicle that breaks down dangerous compounds. Another organelle that is involved with the breakdown of chemicals in the cell is the mitochondria. They change the fuel into carbon dioxide and water, while storing ATP. ATP is adenosine triphosphate (Postlethwait, Hopson, & Veres, 1991), which is a molecule that stores energy in a cell. The ATP is then used throughout many other cellular processes as an energy…

Melnik, B., Jansen, T., & Grabbe, S. (2007). Abuse of anabolic-androgenic steroids and bodybuilding acne: An underestimated health problem. Journal Der Deutschen Dermatologischen Gesellschaft, 5(2), 110-117. doi:10.1111/j.1610-0387.2007.06176.x Within this article it is discussed that the Abuse of anabolic-androgenic steroids by members of the fitness world seems to be ever increasing and have reached alarming dimensions. It is stated that the health care system provides the illegal…

Early detection and diagnosis of chronic disease is of vital importance in the development of an effective treatment plan. Typical diagnostic methodology involves a multistep approach consisting of a differential diagnosis, pattern recognition, and a final clinical component. The lengthy process must be completed before any treatment options are considered often resulting in over/under diagnosis, error, and lag-time. It would be of great benefit to develop a more effective system to heighten the…
