Bio revision 0.0 / 5 ? BiologyBiological moleculesASAQA Created by: Zane MistryCreated on: 13-01-16 10:30 What is absorption? Taking molecules into thebody 1 of 20 What is assimilation Incorporating absorbed molecules into body tissue 2 of 20 What is the structure of glucose? . 3 of 20 What is maltose broken down into? Glucose + Glucose 4 of 20 What is sucrose broken down into? Glucose + Fructose 5 of 20 What is lactose broken down into? Glucose + Galactose 6 of 20 How is a bond broken down? Hydrolysis reaction 7 of 20 How is a bond formed? Condensation reaction 8 of 20 Lactose (lactose intolerance) digested in SI --> epithelial lining produces lactase. Low lactase= high lactose= broken down by microorganisms= gas=bloated 9 of 20 Test for Reducing Sugar Add Benedicts, heat= red 10 of 20 Test for Non-Reducing Sugar Do Reducing test. If not red then add HCL to break down. Add sodium hydrocarbonate to neutralise. Do Reducing test again. 11 of 20 Test for proteins Add sample, add sodium hydroxide, add dilute copper sulfate= purple 12 of 20 Test for Iodine Add sample, add iodine=turns blue/black 13 of 20 Test for lipids Add sample, add ethanol, shake, pour into water. lipid= cloudy 14 of 20 Structure of a protein . 15 of 20 What bonds are between protiens? Peptide bonds 16 of 20 Lock and key model Enzyme substrate complex, substrate specific 17 of 20 Induced fit Enzyme changes shape to fit around the substrate. 18 of 20 Non competitive inhibitor Binds to allosteric site (not active site), causes bonds to break in active site= changes shape= innactive 19 of 20 Competitive inhibitor Binds to active site so substrates can't bind 20 of 20
