Organic Molecules Answers to the text questions. Introduction What is the difference between an organic compound and an inorganic compound? Organic compounds are based on carbon and are found in living things. Exceptions to this are: CO2, and CO. Inorganic compounds are other molecules. Carbohydrates Draw a glucose molecule. 6 carbons Carbohydrates Draw a ribose molecule. 5 carbons Carbohydrates Give three examples of the following: Monosaccharide Glucose Fructose Galactose Carbohydrates Give three examples of the following: Disaccharide Maltose Lactose Sucrose Carbohydrates Give three examples of the following: Polysaccharide Starch Cellulose Glycogen Carbohydrates In animals, what are the functions of: a. glucose Glucose is used in cellular respiration to create ATP. b. lactose Lactose is a milk sugar, which serves to store glucose. c. glycogen Glycogen serves as a shortterm way to store glucose. It is stored in our liver. Carbohydrates In plants, what are the functions of: a. fructose Fructose is the sugar found in fruits. Plants use it to form sucrose, which will form starch, plants’ energy storage molecule. b. sucrose Sucrose is a soluble sugar that is transported in sap, which will be converted to starch. c. cellulose Cellulose provides structural support in the cell wall. Lipids Draw the basic structure of a fatty acid. Lipids Give 3 functions of lipids. Energy storage In animals, energy is stored as fat (triglycerides). In plants, energy is stored as oil Thermal Insulation A layer of fat beneath the skin, called the subcutaneous, insulates against heat loss. This is not a triglyceride. Buoyancy Lipids are less dense than water, so therefore helps animals float. Lipids Compare the use of lipids and carbohydrates in energy storage. Proteins Draw acid. the basic structure of an amino • An amino group • An R Group • A carboxylic acid Making and Breaking Polymers Define A chemical reaction that combines two monomers into a polymer, and in the process creates a water molecule. Define condensation hydrolysis A chemical reaction that breaks down polymers, and in the process splits a water molecule. Seeing the difference!
