Carbohydrates A carbohydrate is one of three macronutrients and is the most important energy source for the entire body. Men’s Health Magazine talks about how Today people are mislead by diets such as the atkins diet and sugar busters diet. These diets deceive us into thinking that our bodies actually don’t need carbohydrate and that our bodies would rather rely on fats and proteins for energy. According to the text book Nutrition An Applied Approach, this information is false, that in reality our bodies actually prefer to use carbohydrates and fats for energy, and that 60% of our daily intake needs to be Carbohydrates. When doing high intensity short duration workouts such as weight lifting our bodies rely on carbohydrates for energy. This energy produced from carbohydrates is called adrenosine triphosphate also known as ATP. What happens is the carbohydrates are broken down into glucose and undergo a process called glycosis to create this ATP. The end result of all of this is pyruvic acid. When your doing these high intensity exercises the oxygen in your cells become limited and then the pyretic acid converts to lactic acid to supply fuel for our muscles and our hearts. If a person is not consuming enough carbohydrates their body and brain then has to use alternative options for energy which can lead to ill health. Lets start with the brain, in my textbook, it says the brain on average uses 130 carbohydrates daily to function at normal capacity, so if there are not sufficient carbohydrates our body will then start to make its own energy called ketones through a process called ketosis. Ketosis is normal however if the brain has to continue using ketones for energy serious side effects can occur such as suppressed appetite, dehydration, and high blood ketone levels. Ketones are highly acidic and can interfere with everyday body…
also one of the most prevalent and debilitating conditions.
Diabetes is a chronic disease or condition that involves the hormone insulin, which helps regulate the amount of glucose in a person’s bloodstream. When cells are in need of energy the pancreas produce insulin, this mechanism allows cells to absorb glucose from the bloodstream. If the pancreas produce too little or no insulin or if the insulin doesn’t work properly the person may become diabetic. Therefore, diabetics are not able to…
present inside the test tubes. It is included as a test sample because its composition contains no macromolecules.
Biuret Test for Protein- Distilled water, Starch, Glucose, Apple juice
These are the samples in which the color change didn’t occur and it contained no proteins.
Iodine Test for Starch- Distilled water, Albumin, Glucose, milk, whip cream, apple juice, gelatin
These are the samples in which the color change didn’t occur and it doesn’t have any starch in it.
Test of Reducing Sugar (Benedict’s)-…
sugar (glucose) levels that result from defects in insulin secretion, or its action, or both. Diabetes mellitus, commonly referred to as diabetes was first identified as a disease associated with "sweet urine," and excessive muscle loss in the ancient world. Elevated levels of blood glucose lead to spillage of glucose into the urine, hence the term sweet urine.
Normally, blood glucose levels are tightly controlled by insulin, a hormone produced by the pancreas. Insulin lowers the blood glucose level…
1. Photosynthesis is the process of converting light energy to chemical energy and storing it in the bonds of sugar glucose . The process of photosynthesis usually takes place in plants, seaweeds, algae, and certain types of bacteria. The plants capture the energy of the sun by the chemical process. They also produce sugar glucose as their foods and they usually produce more than enough sugar glucose to survive. Although for some it may seem like a waste but it’s actually…
Earth, all living organism obtain the energy necessary to sustain life, from the oxidation of organic substances by molecular oxygen, in the process of respiration. Under anaerobic condition (no oxygen or low oxygen concentration), many organism, including yeast obtain the energy from the process of fermentation. In alcoholic fermentation, characteristic of many yeast species, the fermentation process starts with one molecule of the six carbons sugar- glucose, and terminates with two molecules of…
O(oxygen), in a 1:2:1 ratio. Carbohydrates can be divided into three groups, monosaccharaides (one simple sugar), disaccharides (combination of two simple sugars), and polysaccharides (combination of three or more simple sugars). Monosaccharaides is glucose, disaccharides is sucrose, and polysaccharide is starch. Monosaccharaides and disaccharides have two hydroxide groups bonded to the carbon backbone plus an aldehyde or ketone group, and polysaccharides is made of several covalently bonded monosaccharides…
Experiment 2. The test for glucose
(a) Half fill a beaker with tap water and place it on a tripod and gauze. Heat the
water with a Bunsen burner. While waiting for the water to boil, carry on with instructions (b) to (d).
(b) Label four test-tubes 1-4.
1% starch solution into tube 1
10% glucose solution into tube 2
(c) Put 20 mm (depth) of…
homeostasis of the blood pH and balance of the electrolytes.
3. Describe metabolism.
Metabolism is all the chemical reactions of the body.
Catabolism occurs during decomposition reactions and releases energy. (Exergonic)Covalent bonds are broke, smaller molecules are produced and energy that is used during Anabolism is released. Anabolism occurs during synthesis reactions(Endergonic) and produces protein or fat.
4. Explain the importance or water in living organisms.
Water is the universal…

Lab: Testing for Nutrients
Purpose: To observe the indicator reaction test for specific nutrients and test for the presence of lipids, carbohydrates and proteins.
Substances in food that can be used by an organism for energy or for growth and repair are called nutrients. Nutrients include carbohydrate, proteins, fats, minerals, and vitamins. Cells of all organisms are composed of the nutrients and water. There are several chemical tests that can be used to determine which…
