The Different Roles of Macromolecules in Biology.There are four types of macromolecules that I am going to describe: Proteins‚ carbohydrates‚ lipids and nucleic acid. I will also describe the functions and why they are important in our bodies. Proteins Proteins are polymers of amino acids that are joined head-to-tail in a long chain that is then folded into a three-dimensional structure unique to each type of protein. The covalent linkage between two adjacent amino acids in a protein (or polypeptide)

DIGESTION OF CARBOHYDRATES Digestion of carbohydrate begins in the mouth‚ with the secretion of the enzyme salivary amylase from the serous cells of the salivary gland. This enzyme breaks starch and glycogen into disaccharides. The mucous cells of the salivary gland secrete a mucus‚ which causes the food to stick together‚ and acts as a lubricant to aid in swallowing. The salivary glands are grouped into three categories: the parotid gland‚ submandibular glands‚ and sublingual‚ all located

out if the food you picked contained starch‚sugar‚lipids and protein.The food item that was chosen to decipher was a Big Mac and you chose what from the burger you wanted to test to see what it was made of‚ example like the bun of the burger. When testing you would have one test tube of water with food and the other test tube with the solution needed and food.The reason for the test tube with the water is because it was the indicator. If the product of food contained the macromolecule that was tested

Digestion is the complex process of turning the food you eat into the energy you need to survive. The digestion process also involves creating waste to be eliminated. The digestive tract (or gut) is a long twisting tube that starts at the mouth and ends at the anus. It is made up of a series of by muscles that coordinate the movement of food and other cells that produce enzymes and hormones to aid in the breakdown of food. Along the way are three other organs that are needed for digestion: the liver

The Released: What happens after the mentally ill are released from prison. Abstract Mental illness has been around since the beginning of time. Back in the 1940s or ’50s‚ a man with schizophrenia would have been locked away in an isolated state mental hospital. In the 1960s or ’70s‚ following the widespread deinstitutionalization of people with mental illness‚ he likely would have been released. Now the future for people with mental illness could be very different. The most likely place

organs working together to convert food into energy and basic nutrients to feed the entire body. Food passes through a long tube inside the body known as the alimentary canal or the gastrointestinal tract (GI tract). The alimentary canal is made up of the oral cavity‚ pharynx‚ esophagus‚ stomach‚ small intestines‚ and large intestines. In addition to the alimentary canal‚ there are several important accessory organs that help your body to digest food but do not have food pass through them. Accessory organs

Running head: METABOLISM Metabolism February 12‚ 2013 Western Governor’s University GRT1 Metabolism Enzymes are molecules that are responsible for chemical reactions that occur within the body. They act as catalyst by accelerating metabolic reactions from the digestion of foods to synthesizing deoxyribonucleic acid (DNA). An enzymatic reaction changes substrates‚ the beginning molecule‚ into products. Enzymes are selective for the type of substrate that they will bind to; they have specific

Week 7 Digestion Lecture Study Guide Based on information found in the lecture folder or other sources‚ answer the following questions. 1. What is digestion? Digestion is the mechanical and chemical breakdown of food into usable molecules 2. List some other names of the digestive tract. Alimentary Canal (GI Tract) 3. Explain where and how the mechanical breakdown of food occurs. Teeth begin digestion mechanically‚ Chewing (“mastication”) breaks apart food‚ 2 sets
