Nutrients: Fats, Proteins. Carbohydrates, Water, Vitamins & Minerals

506 words - 3 pages

A nutrient is any food substance that is necessary for contributing to an organism's growth and metabolism. There are 6 nutrient groups, classified as those that provide energy and others that support metabolic processes in our body. Some of these are very important because they cannot be produced in the body and have to be taken from a food source. Nutrition is the taking in and use of nourishing materials by the body. Different organisms have different ways to take in nutrients, like plants taking nutrients through photosynthesis and the use of their roots. Nutrition is also a science that focuses and studies the relationship between diet, health and disease. For ...view middle of the document...

There are also more complex carbohydrates like starches and fibers, which provide longer-lasting energy. These more complex types are stored in the body as glycogen.Proteins: These are organic compounds, that provide the building blocks for enzyms and other proteins in the body. Our body doesn't make certain amino acids (building blocks), and so we get these amino acids with our diet.Fats: fats are basic nutrients made up of carbon, hydrogen, and oxygen atoms. They are used for cells to properly function and maintenance of body temperature. The body does not make some fatty acids and again we look for our diet to supply these. Triglycerides make up 95% of our total body fat, and cholestetrol makes up the rest.Nutrients that supply metabolism:Minerals: Essential to metabolism. Found as salts, or ions like copper and iron. List of some Minerals•Chromium•Cobalt•Copper•Fluorine•Iodine•Iron•Manganese•Molybdenum•Selenium•ZincVitamins: organic compounds essential to the body's functions, usually acting as coenzymesWater: Very important necessity for normal growth and metabolism and other body functions.Any classification of "nutrients" is likely to be arbitrary given the status of nutrition as a developing science. Researchers are becoming more aware of a wider range of nutrients essential for health.Bibliography:southwest.mpls.k12.mn.us/sites/ad26dc17-c8bc-4970-8795-bae99167aab3/uploads/Option_A.pptwww.rodsmith.org.uk/alternative-health/Alternative-health-glossaryN-Q.htmMicrosoft Encarta Encyclopedia 2001

Do not have strong walls.Translocation*Movement can be in any direction but always moves from where sugar is in abundance (sugar source) to where sugar is needed (sugar sink)Sugar is made in photosynthesizing cells of the plant and can be polymerized and stored as starch in any cells of the plant. The sugar produced in photosynthesis is called glucose. The starch is broken down

Cells use diffusion to take in things from their environment and rid themselves of waste. Diffusion takes place down a concentration gradient. Water, carbon dioxide and other small ions can diffuse freely through cell membranes. Concentration gradients occur in all organisms. Where they do, simple diffusion will transport things around. Nutrients being carried

The Rate Of Photosynthesis

3760 words - 16 pages chemicals such as fats, proteins and vitamins. The oxygen released as a by-product, vital to respiration in plants and animals. Therefore, photosynthesis can be considered the ultimate source of energy for life and for nearly all plants and animals by providing the source of energy that drives all their metabolic processes (Infoplease, 2012)Considering our knowledge has increased in understanding what photosynthesis is, we now need to learn how

Transpiration In Plants

1309 words - 6 pages Transpiration is the process that allows plants to release H20 in the form of water vapor into the atmosphere. This process mostly occurs during the time the stomata, the microscopic pores on the surface of a leaf, are open for the passage of CO2 and O2. Transpiration plays a huge role for plants, as 90% of the water that enters the plant is through transpiration. It also allows the plant to receive key nutrients and minerals in order to survive
