1 Quiz Review Select a topic to complete a short review. Macromolecules Review Cell Review QUIT

2 Macromolecules Review Let’s go!

3 Made up of 2 anti-parallel strands of nucleotides: DNARNA

4 When 2 molecules are joined and a water molecule is removed in the process: Dehydration Synthesis Hydrolysis

5 On the DNA molecule, Thymine always pairs with: AdenineGuanine

6 Enzymes work as catalysts by: Decreasing the activation energy of a rxn Decreasing the free energy of a rxn Bypassing the transition state of a rxn

7 The functional groups found in a monosaccharide: Carbonyl and hydroxyl Glycosidic and hydroxyl Carboxyl and hydroxyl

8 Difference between starch and cellulose: Starch have  1-4 glycosidic linkage, while cellulose has  1-4 glycosidic linkage In starch some glucose monomers are oriented upside down. Cellulose has  1-4 glycosidic linkage, While starch has  1-4 glycosidic linkage

9 When a maltose goes through a hydrolysis reaction, the products will be: 2 glucose molecules 1 glucose and 1 fructose molecules 2 sucrose molecules

10 The number of fatty acid chains on a phospholipid: Two One Three

11 Vegetable oils are liquid at room temperature due to: Presence of double bonds, resulting in kinks on the fatty acid chains Having fully saturated fatty acid chains Its ability to form hydrogen bonds with water

12 Which of the following is FALSE? There are 12 essential amino acids 8 of the amino acids must be obtained from our diet Some amino acids are polar, some non-polar & some electrically charged

13 In a condensation reaction between glycerol and fatty acids, the following linkage is formed: Ester Glycosidic Peptide

14 The following diagram represents: Steroid Protein Amino acid

15 The second diagram below represents: Non-competitive inhibition Competitive inhibition Functional enzymes

16 Alpha helix and beta pleated sheets represent a protein’s: Secondary structure Primary structure Tertiary structure

17 In a hydrolysis reaction: Polymer is broken down into smaller units and energy is released Monomers are joined together and energy is released No energy is required

18 The following is a general structural formula for: Amino acids Nucleic acid Triglycerides

19 Component of the cell membrane: Phospholipids Triglycerides Triacylglycerols

20 Which of the following does NOT contribute to a protein’s tertiary structure: Peptide bond Disulfide bridge Proline kink

21 Component of the nucleic acid: A phosphate group, 5-carbon sugar and nitrogenous base A glycerol, a phosphate group and 2 hydrocarbon chains An amino group & a carboxyl group both attached to central carbon

22 The bond that links one nucleotide to another on one strand of DNA is: Phosphodiester bond Hydrogen bond Peptide bond

23 Congratulations You have reached the end of the quiz. Score NEXT STAGE

24 Cell Review Let’s go!

25 The mitochondria is responsible for: Creating energyDisposing of waste

26 A cell is filled with _________. CytoplasmAir

27 This controls the functions of the cell. Golgi BodyNucleus

28 Which of the following is NOT a characteristic of plant cells: Numerous small vacuoles Cell wall Chloroplasts

29 Primary function of cytoskeleton in cells: Provide structure, shape, support & stability Allow endocytosis and exocytosis to occur Keeps organelles from moving around

30 The passage of RNA from nucleus to the cytoplasm is controlled by: Nuclear pore complexes Cytosol Nucleolus

31 In a non-dividing cells, a complex mixture of DNA and proteins that represent the unfolded state of chromosomes is called; Chromatin Centrioles Sister chromatids

32 With regards to mitochondria and chloroplasts: Both contain some of their own DNA Both are found in animal cells Both function to provide energy to cells

33 Grana are: Stacks of chlorophyll-containing thylakoids Grain-like features seen on Endoplasmic Reticulum Found within the cristae of mitochondria

34 Which of the following is FALSE: Smooth ER synthesizes proteins and lipids Plant cells contain a large central vacuole The fluid in the cytoplasm is called cytosol

35 Lysosomes are: Produced by Golgi apparatus and contain enzymes that do hydrolysis rxn Produced by ER and contain enzymes that do redox rxn Produced by the mitochondria for transport of proteins

36 Congratulations You have reached the end of the quiz. Score HOME
