- 1What are monomersSmall, basic molecular units that make up Polymers
- 2Name 3 MonomersMonosaccharides, Amino Acids and Nucleotides
- 3What are PolymersLarge, complex molecules composed of long chains of monomers
- 4Name 3 examples of PolymersCarbohydrates, Proteins and Nucleic Acids
- 5What 3 elements do all Carbohydrates contain?Carbon, Oxygen and Hydrogen
- 6What Monomers are Carbohydrates made from?Monosaccharides
- 7Name the 3 monosaccharidesGlucose, Fructose and Galactose
- 8How many isomers of glucose are there?2
- 9Name the 2 isomers of Glucoseα-glucose and β-glucose
- 10What are the structures of the 2 isomers of GlucoseEnter text here...
- 11What type of reaction joins Monosaccharides together?Condensation reaction
- 12What bond forms between 2 monosaccharides?1,4-glycosidic bond
- 13What disaccharide forms in a reaction between 2 α-Glucose molecules?Maltose
- 14What disaccharide forms in a reaction between a glucose molecule and a fructose moleculeSucrose
- 15What disaccharide forms between a glucose molecule and a galactose molecule?Lactose
- 16What reaction breaks Polymers?Hydrolysis reaction
- 17What test is used to check for reducing and non-reducing sugarsBenedicts test
- 18Which 2 polysaccharides make up Starch?Amylose and Amylopectin
- 19What does Starch store?Excess Glucose
- 20What properties of Starch make it good for Storage?Insoluble in water, and doesn’t affect water potential
- 21What test is used for Starch?Iodine test
- 22Where is Starch found?In plants
- 23What does glycogen store?Excess glucose
- 24What characteristic makes Glycogen good for energy releaseIt has many side branches
- 25What characteristic of Glycogen makes it good for storageIt is very compact
- 26What do both Starch and Glycogen contain?α-Glucose
- 27Where is cellulose foundPlants
- 28What is cellulose made up ofβ-glucose
- 29What are cellulose chains linked together byHydrogen bonds
- 30What do multiple linked chains of cellulose formmicrofibrils
- 31Name the 2 types of lipidTriglyceride and Phospholipid
- 32What is the structure of a TriglycerideEnter text here...
- 33What reaction forms TriglyceridesCondensation reaction
- 34What bonds form between the glycerol and fatty acidsEster bond
- 35What is the structure of phospholipidsEnter text here...
- 36What are triglycerides used forEnergy Storage Molecules
- 37What makes triglycerides good for energy StorageTheir long hydrocarbon tails contain lots of chemical energy, and they’re insoluble so don’t affect water potential
- 38What are phospholipids used forTo form cell membrane bilayers
- 39Why do phospholipids make good cell membrane bilayersThey have hydrophilic heads and hydrophobic tails, so they form a double layer with a hydrophobic centre to block water soluble substances from passing through
- 40What test is used to identify lipidsThe emulsion test
