proteins and nucleic acids. The most important organic molecule is Carbon. Carbon can form with up to 4 different atoms to form chains‚ rings and branches. Organic molecules also contain monomers. Monomers are the “building blocks” of macromolecules. Macromolecules are made up by chains of monomers‚ these are called polymers. Continuing with the four organic molecules are proteins. Proteins provide structure and function and have the chemical structures of Carbon‚ Hydrogen‚ Oxygen and Nitrogen.

Proteins‚ lipids‚ and carbohydrates are essential to not only the human body‚ but plants and animals too. Because we know about these macromolecules‚ we can better understand the world around us. They play a vital role in keeping us healthy and aiding in the diagnosis of medical conditions‚ they are responsible for what keeps us running and they are vital in even the tiniest forms of life;
Premium Carbohydrate Glucose Metabolism
ENERGY RESERVES OF MACROMOLECULES SUMMARY This experiment was conducted in order to show the energy received from the food that humans eat on a daily basis. The energy that is required by the human body to perform chemical reactions is obtained from the chemical bonds that formed between the atoms in the molecules. To calculate the amount energy‚ types of food products were burned underneath a test-tube filled with water. The temperature rise gave an estimate of the energy released per gram.

We have four important macromolecules; carbohydrates‚ lipids‚ proteins‚ and nucleic acids. From these four‚ the macromolecule I chose for this assignment was carbohydrate. Carbohydrates branch off into three main categories; monosaccharides‚ disaccharides‚ and polysaccharides. I decided to focus on disaccharides‚ specifically sucrose. Sucrose is more commonly known as table sugar. It has a chemical formula of C12H22O11. It is physically described as a white‚ odorless (although when heated‚ it may
Premium Glucose Carbohydrate Protein
In biology‚ there are four major biological macromolecules that are found in the cell‚ carbohydrates‚ lipids‚ nucleic acid‚ and proteins. Biological macromolecules are also known as organic molecules. Biological macromolecules are very large molecules that are of a key importance to living organisms. Most biological macromolecules are built by joining smaller molecule subunits. Carbohydrates are large groups of organic compounds found in foods such as sugars‚ starches‚ glucose‚ fructose‚ galactose

Carrying out research by field experiment means the researcher can allocate pupils into high streams and low streams and measure the effect. This means that the sociologist can compare the higher and lower streams and look at the impact on how to sets have. This will let the sociologist see if streaming actually makes a difference between achievements. Setting up and carrying out the field experiment is quick and easy because nearly all schools have streaming. This means that the sociologist can

For the scientist’s experiment the scientist will be experimenting with additives and gel. We will be adding different substances such as table salt‚ citric acid‚ and sugar. The scientist’s problem statement is “What kind of substances make gel the strongest?” The independent variable will be the different additives (Table salt‚ citric acid‚ and sugar) which will be added using tablespoons. The dependent variable is the strength of the gel which will be measured using a scale of 10. The constant

How to Write a Lab Report Lab reports are formal papers that describe and analyze lab experiments. They follow a very specific format. If you study this paper carefully and follow its directions‚ you will find that these papers are not at all difficult and can have a positive impact on your Biology grade. Paper formatting: The paper should be typed and double spaced. Use a standard 12 point font (do not use cute fonts or colored paper!). Except for the title and abstract – each section

Unit 1: 1. What are the different parts of an experiment? a. Control group b. independent variable c. dependent variable d. all of the above 2. Match the following terms to the correct statement. a. Independent Variable b. Control Group c. Dependent Variable The control group is the part of the experiment where the independent variable being tested is not so that it may serve as a standard for comparison. In an experiment it is the independent variable that is manipulated
