How the structure of proteins are related to their functions Rachel Morris The basic building blocks of proteins are amino acids‚ the biuret reaction tests for protein. A solution of sodium hydroxide is added to a sample then a few drops of copper sulphate solution‚ if positive – the solution will turn mauve. There are 20 different amino acids and they can be joined in any order. Therefore there can be many different functions. A protein consists of one or more polypeptide chains (a polypeptide

Samantha Hutchins 10/27/15 Vitamin D Deficiency Regarding Muscles Vitamin D deficiency has been tied to mainly bone pathologies. Recent research shows that the effects of Vitamin D span further than just affecting bones and particularly cause muscle weakness. Vitamin D is responsible for aiding in the absorption of other minerals‚ such as calcium. Calcium is a key ligand in muscle contractions‚ thus‚ Vitamin D indirectly can effect muscle contractions.

Metabolism is the mechanism that creates order and complexity from chaos‚ by acquiring and expending energy. Heredity is the ability of an organism to copy itself and it is broken down into: i. Multiplication‚ ii. Inheritance‚ iii. Variation. 2. DNA codes via RNA for 20 of naturally occurring amino acids. Amino Acids are the building blocks of proteins and bodies. DNA stores and transmits

Chronic Training Adaptations Exercise or training regularly over an extended period of time (3 times per week for 6-8 weeks) leads to the development of long-term or chronic adaptations to training. Evidence of these adaptations can occur at various stages Once achieved‚ these adaptations are retrained unless training ceases. Upon cessation‚ the body will gradually revert to its pre-training condition (de-training). Unlike acute responses to exercises‚ chronic adaptations to training

Cross-reactive epitopes are present in the streptococcal M protein and the N-acetylglucosamine of group A streptococcal carbohydrate and are immunologically similar to molecules in human myosin‚ tropomyosin‚ keratin‚ actin‚ laminin‚ vimentin‚ and N acetylglucosamine. It is currently thought that the initial damage is due to cross-reactive antibodies attaching at the cardiac valve endothelium‚ allowing the entry of primed CD4+ T cells‚ leading

Rigor sets in 1 to 2.5 hours and it can last up to 6 to 12 hours‚ it is depending on the type of an animal. During this stage enzymes start to break down the muscle fibers. “The muscle fibers begin to act on the framework which holds the actin and myosin filaments‚ overall muscle structure weakens and meat softens” (McGee‚ 2004)

During exercise your body must adapt to the added stress and pressure you are putting onto it. The heart plays a very important role in maintaining homeostasis during exercise. When exercising your heart rate increases and the “Left Heart” have to pump out more oxygenated blood to the entire body. The sympathetic nervous system also plays an important role during exercise. The sympathetic pathway comes out of the lower cervical and upper thoracic segments of the spinal cord. The sympathetic
