1. What four classes of organic compounds are required by living things, and how are they used in the body? Science Standard 8.6.b Science Standard 8.6.b: Students know that living organisms are made of molecules consisting largely of carbon, hydrogen, nitrogen, oxygen, phosphorous, and sulfur. Science Standard 8.6.c Science Standard 8.6.c: Students know that living organisms have many different kinds of molecules, including small ones, such as water and salt, and very large ones, such as carbohydrates, fats, proteins, and DNA.

2. Carbohydrate Glucose complex carbohydrate Starch Cellulose Lipid fatty acid Cholesterol nucleic acid DNA RNA nucleotide

3. COMPARE & CONTRAST All are foods & have carbon polymers. Taste, texture, chemical makeup.

4. Life With Carbons The four classes of organic compounds required by living things are… carbohydrates proteins lipids nucleic acids THIS GIVES Living Things THE ENERGY AND RAW MATERIALS IT NEEDS

5. Carbohydrates: The body breaks down starch into glucose, which is used by the body as energy to carry out its life functions. SUGAR IS THE SIMPLEST CARB Starch and Cellulose are 2 COMPLEX CARBS made from glucose. Carbohydrate Glucose Complex carbohydrate Starch Cellulose

6. Proteins: The body uses proteins from food to build and repair body parts and to regulate cell activities Feathers, scales, nails are all made of proteins

7. Lipids: Gram for gram, lipids release twice as much energy in your body as do carbohydrates. Lipids Fatty acids Cholesterol

8. Nucleic Acids: When living things reproduce, they pass DNA and the information it carries to the next generation. Nucleic Acid DNA RNA Nucleotides

9. Other Nutrients Organisms require water, vitamins, minerals, and salts to support the functioning of large molecules. Water makes up about 90% of the liquid part of blood. Nutrients are dissolved in the watery part of blood and carried throughout the body.

10. Other Nutrients water, vitamins, minerals, and salts Organisms require water, vitamins, minerals, and salts to support the functioning of large molecules. Vitamins helper molecules used in a variety of chemical reactions. Minerals elements in the form of ions needed by the body. Salts ionic compounds that help the body in such processes as muscle contraction, bone growth, and pH balance.

11. The Molecules of Life Complex carbohydrates, proteins, lipids, and nucleic acids are all large organic molecules. They are built of smaller molecules linked in different patterns.

12. Substances that provide the energy and raw materials the human body needs are A. nutrients. B. substituted hydrocarbons. C. esters. D. unsaturated hydrocarbons. A

13. The classes of organic compounds found in all living things are A. halogen compounds, alcohols, organic acids, and esters. B. carbohydrates, lipids, proteins, and nucleic acids. C. vitamins and minerals. D. simple carbohydrates and hydrocarbons. B

14. Which organic compound carries information from one generation to the next during reproduction? A. carbohydrates B. lipids C. proteins D. DNA D

15. Gram for gram, which organic compounds release twice as much energy in your body as do carbohydrates? A. vitamins B. lipids C. Proteins D. nucleic acids B
