Higher Biology Knowledge Organiser Unit 2

Stop rereading—start remembering. This Unit 2 organiser turns the full topic into structured retrieval practice: key definitions, processes, and exam vocabulary in a quick-fill, active recall format (perfect for self-quizzing and rapid topic checks).

Includes 7 pages covering:

Metabolic pathways (enzyme-catalysed reactions, anabolic vs catabolic, reversible/irreversible steps)

Enzymes + control of pathways (induced fit, substrate/product concentration, competitive & non-competitive inhibition, feedback inhibition)

Cellular respiration (glycolysis, citric acid cycle, electron transport chain, ATP synthase) + fermentation

Metabolic rate (measuring oxygen consumption/CO₂/heat) + circulatory systems (fish, amphibians/reptiles, birds/mammals)

Conformers vs regulators + thermoregulation (negative feedback + corrective responses)

Dormancy + migration (predictive vs consequential, hibernation/aestivation/torpor, tracking methods)

Micro-organisms (growth media & conditions, growth phases, viable vs total cell counts) + recombinant DNA technology (vectors, restriction enzymes, ligase, selectable markers)

Perfect for: Higher Biology students, prelim prep, quick revision, homework check-ins, and “I need to test myself fast” sessions.
