BW Abitur Biology Bilingual EN study plan

BW Abitur Biology Bilingual EN · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Zellbiologie / Cell biology (structure and function of cells, membranes, transport, enzymes, compartmentalisation) & Wissenschaftliche Arbeitsweisen / Scientific practices (experimental design, data analysis, interpretation of models, evaluation, scientific communication in English)

  • Describe the structure and function of the endomembrane system, mitochondrion, chloroplast and cytoskeleton, and explain how compartmentalisation increases metabolic efficiency

  • Distinguish passive diffusion, facilitated diffusion, active transport and osmosis by predicting the direction and energy cost of solute movement in a given scenario

  • Explain enzyme kinetics using Michaelis-Menten terminology (vmax, KM, competitive vs non-competitive inhibition) and sketch the corresponding graphs from memory

  • Design a controlled experiment on enzyme activity (e.g. temperature or pH dependence of catalase) and identify independent, dependent and controlled variables

Your checkpoint

A one-page labelled cell-compartment map plus a written experimental protocol for the catalase experiment with variables table and predicted graph

Week 2

Stoffwechsel und Energieumsatz / Metabolism and bioenergetics (photosynthesis, cellular respiration, ATP, enzyme kinetics) & Zellbiologie / Cell biology (structure and function of cells, membranes, transport, enzymes, compartmentalisation)

  • Trace the flow of energy and electrons through photosynthesis, naming the products of the light reactions and the Calvin cycle and where each step occurs

  • Compare substrate-level phosphorylation, oxidative phosphorylation and photophosphorylation in terms of location, electron carriers and ATP yield

  • Calculate and interpret the ATP yield of aerobic respiration versus lactic acid and alcoholic fermentation

  • Explain how membrane structure underlies chemiosmosis and why the inner mitochondrial membrane is folded

Your checkpoint

A hand-drawn energy-flow diagram linking photosynthesis and respiration, annotated with ATP/NADH yields and membrane locations, plus five self-written calculation items with worked solutions

Week 3

Genetik und Gentechnik / Genetics and genetic engineering (Mendelian inheritance, DNA replication, transcription and translation, mutation, gene technology) & Wissenschaftliche Arbeitsweisen / Scientific practices (experimental design, data analysis, interpretation of models, evaluation, scientific communication in English)

  • Solve dihybrid and sex-linked crosses, including testcrosses, and use chi-square reasoning to judge whether observed ratios deviate significantly from expectation

  • Describe DNA replication semi-conservatively, naming the roles of helicase, polymerase, primase and ligase

  • Explain transcription, RNA processing and translation, and predict the protein change caused by a substitution, insertion or deletion

  • Interpret a pedigree and justify whether a trait is autosomal or X-linked

Your checkpoint

A worked problem set of ten genetics items (crosses, pedigree, mutation consequences) with full reasoning shown for each

Week 4

Genetik und Gentechnik / Genetics and genetic engineering (Mendelian inheritance, DNA replication, transcription and translation, mutation, gene technology) & Immunbiologie und Gesundheit / Immunology and health (immune response, vaccines, allergies, infectious disease)

  • Outline the steps of a gene-technological workflow: restriction digest, ligation into a vector, transformation, selection and screening

  • Explain how PCR, gel electrophoresis and CRISPR-Cas are used and what each method can and cannot show

  • Evaluate ethical and ecological arguments for and against releasing genetically modified organisms

  • Describe the primary and secondary immune response and explain how vaccination exploits immunological memory

Your checkpoint

A 400-word structured evaluation of a gene-technology application (e.g. golden rice or gene-drive mosquitoes) with a labelled workflow diagram and a vaccine-response graph

Week 5

Neurobiologie und Sinnesphysiologie / Neurobiology and sensory physiology (neurons, action potential, synapses, signal transduction, senses)

  • Explain resting potential and the action potential in terms of ion channels, permeability changes and the sodium-potassium pump

  • Describe saltatory conduction and explain how myelin, axon diameter and temperature affect conduction velocity

  • Distinguish electrical and chemical synapses and explain temporal and spatial summation

  • Trace signal transduction from a sensory receptor to perception using one sense organ (eye or ear) as an example

Your checkpoint

An annotated action-potential graph (all phases, ion movements, refractory period) plus a 200-word explanation of one drug or toxin acting on synaptic transmission

Week 6

Evolution und Biodiversität / Evolution and biodiversity (evolutionary mechanisms, speciation, phylogeny, evidence, human evolution) & Wissenschaftliche Arbeitsweisen / Scientific practices (experimental design, data analysis, interpretation of models, evaluation, scientific communication in English)

  • Distinguish the mechanisms of mutation, recombination, selection, drift, gene flow and isolation in producing evolutionary change

  • Explain allopatric and sympatric speciation and apply species concepts to a given case

  • Read a phylogenetic tree and identify shared derived characters, monophyletic groups and misleading branch-length interpretations

  • Assess the strength of evidence for human evolution from fossil, comparative-anatomical and molecular data

Your checkpoint

A phylogenetic tree you construct from a character matrix of eight traits, with a written justification of each grouping decision

Week 7

Ökologie und Nachhaltigkeit / Ecology and sustainability (populations, ecosystems, material cycles, human impact, conservation) & Immunbiologie und Gesundheit / Immunology and health (immune response, vaccines, allergies, infectious disease)

  • Model population growth (exponential vs logistic) and calculate carrying capacity effects from given data

  • Trace the carbon and nitrogen cycles and identify where human activity disrupts them

  • Evaluate a conservation measure using criteria such as biodiversity gain, cost and social acceptance

  • Explain the difference between innate and adaptive immunity and the role of histamine in an allergic reaction

Your checkpoint

A one-page sustainability case analysis of a local or regional ecosystem issue, including a population-growth calculation and a justified management recommendation

Week 8

Wissenschaftliche Arbeitsweisen / Scientific practices (experimental design, data analysis, interpretation of models, evaluation, scientific communication in English) & Genetik und Gentechnik / Genetics and genetic engineering (Mendelian inheritance, DNA replication, transcription and translation, mutation, gene technology) & Neurobiologie und Sinnesphysiologie / Neurobiology and sensory physiology (neurons, action potential, synapses, signal transduction, senses)

  • Analyse unfamiliar data sets and graphs under time pressure, stating the trend, the evidence and a limitation

  • Write full-mark exam answers using command verbs such as describe, explain, compare and evaluate

  • Identify and correct your three most frequent error types from earlier weeks

  • Practise English scientific register: define terms precisely and avoid vague wording such as 'it gets bigger'

Your checkpoint

A timed mock exam under real conditions, self-marked against a checklist, with a written error log and a revised answer for each lost mark

Milestones

Week 2: Without notes, draw and label the energy-flow diagram linking photosynthesis and respiration and state ATP/NADH yields correctly for aerobic and anaerobic pathways

Week 4: Score at least 80% on a self-made 20-item mixed test covering cell biology, metabolism, genetics and immunology; list every missed item with its cause

Week 6: Explain an unfamiliar phylogenetic tree and a pedigree aloud in English in under five minutes each, using correct terminology

Week 8: Complete the timed mock exam within the time limit and reach your target score, with the error log showing no repeated error type from weeks 1-4
