1 Lipids GRT TASK 1 208.5.6 Rosina Lloyd Western Governor's University 2 A. Explain how energy is stored as fat, including identification of storage molecules and tissue. The molecule fat is store in the body in many forms. It can be stored in the body as a carbohydrate, which is used when the supply of fats is limited. Fat is also store in the system as triglycerides that forms three of our good saturated fatty acids.
Lipids are insoluble within water, they have high energy content and can be metabolized to release calories, but they have many other uses as well. Lipids help to create lasting structures within an individual’s body; lipids are also electrical insulators and are needed Bile is secreted from the gall bladder into the digestive tract, and lipase is secreted for
The Role of Fat and it's importance in our diet !1 LIPIDS • Lipids are non soluble molecules that include fats, waxes, sterols, & phospholipids. Lipids main function is storing energy, sending chemical messages in cells, and are components in cell membranes. Lipids make up adipose tissue which is a connective tissue that is made up of lipid cells called adipocytes. Lipids can also be metabolized leading to a large amount of ATP (energy in the body) production. When Lipids are broken down they are broken into a glycerol molecule and fatty acids.
The diet which contains adequate amount of all the essential nutrients like carbohydrates, fats, proteins, minerals and vitamins, sufficient for the normal growth and development of the body Is called a balanced diet. The constituents of a balanced diet are-Carbohydrates, Fats, Proteins, Minerals (Salts), Vitamins, Water and Roughage, Carbohydrates- Carbohydrates are the compounds of carbon, hydrogen and oxygen. They are the main source of energy in our body. There are three types of carbohydrates such as cellulose, starch and sugar, The cellulose does not provide energy to human body, hence It Is not a food. Sugar Is soluble in water.
D) the absence of charged molecules inside cells. Answer: C Page Ref: Section 3 11) The ________ pressure is the pressure required to prevent the flow of solvent through a solvent-permeable membrane that separates two solutions of different solute concentration. A) hydrostatic B) electromotive Answer: C Page Ref: Section 3 12 C) osmotic D) partial 12) Which is true about the solubility of electrolytes in water? A) They are all insoluble in water. B) They are usually only sparingly soluble in water.
All vitamins are classified into two groups that are called fat soluble and water soluble vitamins. Each group acts differently in the body. Fat soluble vitamins dissolve in fat and water soluble vitamins dissolve in water. (Young & Anderson, 2008) The body absorbs fat soluble vitamins through the intestine, and stores the vitamins in fatty tissues and the liver. In order for the process to work properly, there must be sufficient amounts of fat present in the diet.
Diffusion helps to remove dissolved carbon dioxide from the blood and into the expelled air from lungs. Diffusion is the molecules (gas or liquid) moving from high concentration to low concentration. M1: Discuss the role of energy in the body. Our bodies need energy to work properly. The energy we need and use comes from the type of foods we eat.
Fiber, also known as roughage, contains many properties that aid our digestion tract, and allow us to process waste products more efficiently. According to Nutrition.gov (2013) fiber can be found in many of our favorite foods including whole grains, vegetables, and fruits. There are two types of fiber, soluble and insoluble. Soluble fibers dissolve in water, and when digested, “form viscous solutions in the intestines” (Grosvenor & Smolin, 2006). “Fibers that cannot be digested by bacteria in the large intestines are called insoluble fibers because they do not dissolve in water.” (Grosvenor & Smolin, 2006) High fiber diets can produce many benefits, including higher nutrient absorption levels, and better waste output.
2. Most hormones are amino acid based, but gonadal and adrenocortical hormones are steroids, derived from cholesterol. 3. Eicosanoids, which include leukotrienes and prostaglandins, derive from arachidonic acid. B. Mechanisms of Hormone Action (pp.
However, glycogen cannot diffuse through the phospholipid bilayer of the cell membrane so it must be broken down into smaller molecules known as glucose which can diffuse through the glucose co-transport channel protein spun across the phospholipid bilayer. Digestion of carbohydrate is firstly occurs in our mouth when we consume food where enzyme carbohydrase breaks down the carbohydrate into smaller chunk and further transported in the small intestine where it is broken into glucose as the final product of the final digestion. Sometimes, when we do not consume any food glycogen which is a shorter version of carbohydrate in the muscle are broken down producing glucose for respiring cells to produce adenosine triphosphate in the process called glycogenesis. During digestion the 1, 4-glycosidic bonds and 1, 6-glycocidic bonds are broken down by series of hydrolysis reactions. When energy is required by respiring cells, glucose is absorbed or assimilated in the small intestine where other biological molecules also being absorbed such as amino acids and useful fats.
