1 Macromolecules Review ws 1.Name the 6 main elements that make up 95% of an organism. 2.What are macromolecules? 3. Name the 4 classes of macromolecules. C, H, N, O, P, S Carbs, lipids, proteins, nucleic acids Large molecules containing many atoms

2 4.Give 2 examples of nucleic acids. 5.What elements make up carbohydrates & lipids (symbols)? 6.Macromolecules are also known as 7. If all the macromolecules are made mainly of the elements CHO, how are they different? DNA & RNA C, H, O organic. They have different ratios, structures, and properties

3 8.Name 2 ways your body uses carbohydrates. 9.What are the subunits/monomers called that make up carbohydrates? 10. Name 3 monosaccharides. 11.Monosaccharides are also called sugars Energy & structure monosaccharides Fructose, glucose, galacatose simple

4 12. What are disaccharides & give an example? 13. Long chains of sugars are. Name three. 14. What subunits/monomers make up proteins? 15. What is the effect of excess temperature, pH, or salinity on a protein? 2 monosaccharide - sucrose polysaccharides Cellulose, chitin, glycogen & starch Amino acids Changes the shape (denaturing); doesn’t function or function properly

5 16. Chains of amino acids make which can join together to make a 17. makes up cell membranes. 18. Fats are made of an alcohol called and three chains. This is known as a 19. If there are all SINGLE bonds between carbons in the fatty acid chain, then it is said to be 20. If there is a DOUBLE bond between carbons in the fatty acid chain, then it is said to be Phosholipids polypeptides protein. glycerol fatty acids triglyceride saturated unsaturated

6 21.Nucleic acids carry information in a molecule called or acid. 22. are the subunits making up nucleic acid. 23. The 3 parts of a nucleotide are a 5 carbon, a phosphate, and a nitrogen 24. Give the symbols for the elements that make up each of the following: carbohydrates lipids DNA proteins genetic DNA Deoxyribo nucleic Nucleotides sugarbase. C, H, O C, H, N, O, P C, H, N, O, P, S

7 25. Name the function for each for each of the 4 classes of macromolecules. 26. Name the subunits that make up each of the macromolecules. Carbs – energy & structure lipids – long-term energy; insulation; protection Proteins – immune; muscle; transport among other functions Nucleic acid –holds and transports genetic info Carbs – monosaccharide Lipids - none Proteins – amino acids Nucleic acids - nucleotides

8 27.Name the bonds found between amino acids in a polypeptide chain. 28. Explain the difference between a disaccharide and a polysaccharide. Give an example of each. peptide Disaccharide – made of 2 monosaccharides ex – table sugar, lactose Polysaccharide – made of 3 or more monosaccharides ex - glycogen, cellulose, chitin, starch
