Dehydration Synthesis SE (1)[quiz and answers]

Document Content and Description Below

Dehydration Synthesis SE (1)Student Exploration: Dehydration Synthesis Vocabulary: carbohydrate, chemical formula, dehydration synthesis, disaccharide, glucose, hydrolysis, monosaccharide, polysacch... aride, valence Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1. If you exercise on a hot day, you need to worry about dehydration. In this context, what do you think dehydration means? - In this context dehydration means the lack of water in your body has led to more water moving out of cells and bodies than the amount of water you drink. Loosing water and becoming dehydrated can led incoordination. One cause of dehydration is heat exposure especially when exercising. 2. Astronauts and backpackers often bring dehydrated food. What do you think dehydrated food is? - Dehydrated food is a way in which astronauts ins pace preserve their food through the process of dehydration. The food has no water or moisture, which makes the food/package lighter and easier for travel. This is a great way for astronauts to have an endless supply of food with no worries about it expiring. Gizmo Warm-up What do rice, potatoes, and sugar have in common? They are all foods rich in carbohydrates. Carbohydrates are an important energy source for your body. The basic building block of most carbohydrate compounds is the molecule glucose. Using the Dehydration Synthesis Gizmo™, you will learn about the structure of a glucose molecule and how glucose molecules can be joined together to make larger carbohydrate molecules. To begin, select the CREATE GLUCOSE tab.

Look at the chemical formula for glucose. How many carbon (C), hydrogen (H), and oxygen (O) atoms are found in a molecule of glucose? C:6 H:12 O:6 2. Turn on Show chemical structure. Each black sphere represents a carbon, hydrogen, or oxygen atom. The lines connecting the spheres represent chemical bonds. A. How many black spheres are in the diagram? 24 black spheres B. How does this relate to the number of carbon, hydrogen, and oxygen atoms in the chemical formula for glucose? i. It relates to the chemical formula for glucose because it is all of the carbon, hydrogen, and oxygen atoms in the formula added together. (6 + 12 + 6= 24) Activity A: Build a glucose molecule Get the Gizmo ready:  Be sure the CREATE GLUCOSE tab is still selected. Introduction: Each element tends to form a certain number of chemical bonds. This value is the valence of the element. For example, a carbon atom has a valence of four. Goal: Construct a molecule of glucose. [Show More]
