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.

SQA National 5 Biology Unit 2. Key Area 1: Producing New Cells Lesson 1: Mitosis & Lesson 2: Stem Cells Lesson slides including: starter and plenary activities, active learning (some inspired from Leckie and Leckie National 5 Biology textbook), formative assessment, differentiation, vocabulary. These lessons are created according to the course specifications given by the SQA. There are a range of various activities for both lessons. Some require more resources than others. Up to individual schools and teachers to decide what activities are appropriate for their classes. I hope you enjoy teaching this key area and you find the resources useful.
