Fiber Optics Assignment Many modern medical materials and equipment work on a principle which is beyond the capacity of human transducers. Comment and discuss the working principles of an endoscope‚ uteroscope or a rectoscope showing the illuminating path‚ the image path‚ transmission path and the liquid transfer or operating instrument ducts‚ showing the position of suitable valves. This will therefore explain how light travels through an optical fibre and show how such

what are carbohydrates and what is the function of carbohydrates in the body? And secondly‚ what is meant by a low carb diabetic diet? The function of carbohydrates is to provide your body with it’s main source of energy. Your body will either use that energy straight away or store it for later. Carbohydrates are recognised as one of the most important influences on blood sugar levels. Many people with diabetes have found that eating a low carb diabetic diet helps them to control

Carbohydrate Fermentation Testing Questions A. What is fermentation? It is a metabolic process that allows the production of ATP without need for oxygen B. Why is it important not to incubate the fermentation tubes beyond 24 hours? You may not get accurate results. Although sugar is the primary nutrient used‚ when a microbe runs out of it‚ protein or other nutrients will be attacked This causes changes in the color of the medium because of the pH indicator added to detect acid production. When proteins

Proteins play an important role in the human body. The DNA molecule controls the synthesis of proteins. The DNA contains genes which are sequences of nucleotides and bases. Proteins are used for growth and repair. Proteins are made up of amino acids linked together by peptide bonds. Firstly ’amino acid synthesis ’ is the set of biochemical processes by which the various amino acids are produced from other compounds. The substrates for these processes are various compounds in the organism ’s diet

Denaturation of proteins involves the disruption and possible destruction of both the secondary and tertiary structures. Since denaturation reactions are not strong enough to break the peptide bonds‚ the primary structure (sequence of amino acids) remains the same after a denaturation process. Denaturation disrupts the normal alpha-helix and beta sheets in a protein and uncoils it into a random shape. Denaturation occurs because the bonding interactions responsible for the secondary structure (hydrogen

molecular level – Tutoring for biology Saturated fat vs. unsaturated fat Saturated fat has a lot of single carbon bonds. This makes them much straighter in shape and therefore easier to stack together. It’s called “saturated” fat because the molecule has the maximum amount of hydrogen atoms attached to it as possible. Unsaturated fat has double carbon bonds. Each double carbon bond means two less hydrogen atoms on the molecule. Unsaturated fat also is kinked at each double bond‚ disrupting the

High-fat and Low-fat Diets Today‚ more people suffer from weight and health problems than people from twenty years ago. You may ask why is that‚ and what is the difference between us today and the people of the last generation? Well‚ one main difference is the high-fat and low fat foods that we eat. High-fat and low-fat diets can be the cause of half our problems. People today; choose some sort of diet to help their weight problems. But many people do not know what the bad intake of some foods

Fibre is an important part of a healthy diet. A diet high in fibre has many health benefits. It can help prevent heart disease‚ diabetes‚ weight gain‚ some cancers‚ and it can also improve digestive health. However‚ many people don’t get enough fibre. On average‚ most people in the UK get about 14g of fibre a day. You should aim for at least 18g a day. Fibre is only found in foods that come from plants. Foods such as meat‚ fish and dairy products don’t contain fibre. There are two different types

Carbohydrate Powders: During an intense weight training workout‚ the glycogen stored in the muscles and liver is the main energy source. Optimal strength and endurance during your workouts it is very important that these glycogen supplies are completely restored before starting a new workout. The best moment to replenish exhausted glycogen supplies is during the first 2 hours after the workout. Easily digestible food products containing lots of fast absorbing carbohydrates high glycemic index are

Analysis: Lab 1 Identifying Carbohydrates There were many ranges of color changes in the Benedicts test and Iodine stain. For the Benedicts test‚ this oxidation/reduction response changes the arrangement of the reducing sugar creating a colored precipitate. The change in color is correlated to the first concentration of the reducing sugar. For the iodine test‚ the three dimensional structure of various polysaccharides permits them to react with the iodine stain to produce a certain color. As far
