BW Abitur Biology Bilingual EN study guide
BW Abitur Biology Bilingual EN · Work through your exam, one topic at a time.
The Baden-Württemberg Abitur in Biology (bilingual, English) is the school-leaving examination in biology taken at Gymnasien in Baden-Württemberg by candidates in a bilingual German–English stream. It is a school qualification for university entrance, not a professional certification, and it is administered by the schools and the Kultusministerium Baden-Württemberg; this page is an independent study resource and is not affiliated with any examination authority. The BW Abitur Biology Bilingual EN study guide has 8 sections and about 3,466 words.
01Zellbiologie / Cell biology: membranes, transport, compartments and enzymes
Cell-biology items in the BW Abitur test how structure enables function: membrane architecture, transport across membranes, the division of labour between organelles, and the control of reactions by enzymes. Expect data-based tasks - uptake curves, osmosis experiments, inhibition graphs - where you must name a mechanism and justify it from the evidence rather than describe the picture.
446 words, about 2 min02Stoffwechsel und Energieumsatz / Metabolism and bioenergetics
Metabolism items combine pathways with experiments: light-intensity and CO2 curves, the Hill reaction with DCPIP, respirometer readings, and inhibition kinetics. You should be able to place each reaction in its compartment, name its electron carrier, and justify a rate change by identifying the limiting factor.
458 words, about 2 min03Genetik und Gentechnik / Genetics and genetic engineering
Genetics items move from cross and pedigree analysis to molecular mechanisms and to the design of a gene-technological experiment. Marks are lost mainly through imprecise notation: gametes, base polarity, and the difference between template and coding strand must be written correctly.
475 words, about 2 min04Neurobiologie und Sinnesphysiologie / Neurobiology and sensory physiology
Neurobiology items ask you to trace a signal from stimulus to response: ion distributions, the action potential, synaptic transmission, and the transduction step in a sense organ. Many tasks use toxins or ion-concentration changes as experimental probes, so link each manipulation to a specific channel or pump.
425 words, about 2 min05Evolution und Biodiversität / Evolution and biodiversity
Evolution items test mechanism, evidence and phylogeny together. You must distinguish selection from drift, homology from analogy, and be able to compute allele frequencies, because a correct Hardy-Weinberg calculation is a frequent discriminator in the written paper.
408 words, about 2 min06Ökologie und Nachhaltigkeit / Ecology and sustainability
Ecology items link population data to ecosystem processes and to human impact. Typical tasks give a table of population sizes or a food web and ask for a calculation, a limiting factor, or a reasoned conservation measure - always with the mechanism, not just the label.
409 words, about 2 min07Immunbiologie und Gesundheit / Immunology and health
Immunology items expect a clean separation of innate and adaptive responses, correct cell-to-function mapping, and a mechanistic explanation of vaccination or allergy. Graph tasks with antibody titres and questions about why antibiotics fail against viruses are common.
413 words, about 2 min08Wissenschaftliche Arbeitsweisen / Scientific practices
This domain is assessed inside every other topic: it is the marks awarded for designing a controlled experiment, handling data honestly, and evaluating a model. Answers are judged on whether variables, controls and conclusions are stated precisely in English.
