EASE 1 Pointers 2024 Grade 11
Biological Molecule
Proteins
primary structure, secondary structure, tertiary structure, quaternary structure
Peptide bond: is covalent bond that connects/ joins two amino acids, is formed through condensation reaction/ dehydration reaction
Haemoglobin
Testing for biological molecules
Benedict's test for determining the presence of reducing sugar.
Carbohydrates and lipids
Lipids: non polar and hydrophobic, unsaturated and saturated fatty acid, triglyceride and ester bond, phospolipids
Free fatty acid: unsaturated FFA (double bond), saturated FFA (single bond). Non polar (have no uneven distribution of electrical charge), hydrophobic (does not mix
freely with water molecules)
Triglyceride (three fatty acids can combine with glycerol (an alcohol with 3 carbon atoms) and ester bond
Types of carbohydrates: Monosaccharide, Disaccharide, alpha glucose (hydroxyl below), beta glucose (hydroxyl above), glycosidic bon
Cell Structure
Eukaryotic
Animal cell
Plant cell
Prokaryotic
Archaea
Bacteria

Enzyme
Mode of action of enzyme
Intracellular enzyme (Enzyme that works as a catalyst inside a cell). Extracellular enzyme (Enzyme that is secreted and works as a catalyst outside a cell.
Lock and Key Model (Between enzyme and substrate have to be fit with each other)
Induced Fit Model (enzyme active site shape is flexible to the substrate)
Factors that affect enzyme action
Temperature
Ph
