What is your favorite food? _________Pizza_______________________________________________________________ 2. What is food a source of? Large molecules that are needed for life called biomolecules 3. What is a monomer? A monomer is a building block 4. What are bio molecules? Bio molecules are building components of life 5. Carbohydrates are a very important source of… energy 6. The monomers of carbohydrates are called… monosaccharides 7. Lipids are also known as… fats 8. What are the two building blocks of lipids? Fatty acids and glycerol. 9. What are three functions of lipids? Providing insulation, providing long-term energy, and they make up cell membranes. 10. After you run out of carbohydrate energy, where does your body get more energy?From lipids 11. What are the monomers of proteins? Amino acids 12. What are three functions of proteins?Protein helps develop muscle, works the immune system, and acts as enzymes. 13. What are enzymes made of? Proteins 14. What are two examples of nucleic acids? DNA and RNA 15. What do DNA and RNA code for? Our traits 16. What is the monomer of nucleic acids? Nucleotide 17. Write out the names of the elements contained in each macromolecule: a) Carbohydrates:Carbon, Hydrogen, Oxygen b) Lipids:Carbon, Hydrogen, Oxygen

c) Protein: :Carbon, Hydrogen, Oxygen, Nitrogen d) Nucleic Acids: : Carbon, Hydrogen, Oxygen, Nitrogen Task Two – Molecules of Life Tutorial Use any link below to complete the Molecules of Life Tutorial from the CPALMS website. As you complete the tutorial, answer the following questions. Tiny URL: http://tinyurl.com/zvla6qb Full URL: http://www.cpalms.org/Public/PreviewResourceStudentTutorial/Preview/111955 Opening Slide Tab 18. What are the four predominant elements in biology? Hydrogen, Carbon, Nitrogen, Oxygen Molecules Tab – Fill in the blanks. 19. A train is comparable to a macromolecule A train car is comparable to a molecule. 20. What are the building blocks of macromolecules? Monomer 21. When monomers are linked together, the resulting molecule is called a macromolecule. 22. “Mono” means one

“Poly” means many

A monomer is a single molecule

23. A train car is to a train, as a monomer is to a polymer and a molecule is to macromolecule 24. What are the four main classes of macromolecules? 1)

Carbohydrate

2) Lipid 3) protein 4) Nucleic acid Carbohydrates Tab 25. What are two important functions of carbohydrates?Source for fuel and building materials 26. What type of complex carbohydrate is cellulose and what is its role in plant cells? A starch 27. What is another name for a complex carbohydrate? polysaccharide 28. Where do we get all of our simple and complex carbohydrates from?Plants 29. Copy the answers to the practice questions within the activity below: a) Carbohydrate: Main source of energy for living systems b) Monosaccharide: a simple sugar such as glucose which makes up a carbohydrate c) Polysaccharide: complex carbohydrate formed from monosaccharides Lipids Tab 30. What are three functions of lipids: primary components of cell membranes keeping the inside and outside of a cell seperate. A source of energy to a biological system. Some groups of lipids function as hormones which help regulate and maintain homeostasis in organisms 31. Lipids are oily. How do they interact with water? Lipids mix poorly with water Proteins Tab 32. What are proteins made from? Two types of RNA in our cells 33. What cell organelle makes proteins? ___Ribosomes___________________________
