3. Vorschau ausgewählter Lernkarten (Zellbiologie)

Stufe	Vorderseite (Frage / Begriff)	Rückseite (Antwort / Erklärung)
`basic`	What are the three core tenets of classical cell theory?	1. All living organisms are composed of one or more cells. 2. The cell is the basic structural and functional unit of life. 3. All cells arise from pre-existing cells through division.
`basic`	What structural feature distinguishing prokaryotes from eukaryotes is absent in bacterial cells?	A membrane-bound nucleus and membrane-bound organelles (prokaryotes possess a nucleoid instead).
`basic`	What is the distinction between an organism's genotype and its phenotype?	Genotype is the specific genetic makeup and allelic combination; phenotype is the observable physical, physiological, or biochemical traits expressed.
`basic`	What does Mendel's Law of Segregation state regarding allele separation during gametogenesis?	The two alleles for each gene segregate during meiosis so that each gamete carries only one allele for each gene.
`intermediate`	What is homeostasis, and how does a negative feedback loop maintain physiological parameters within set points?	Homeostasis is dynamic physiological equilibrium; negative feedback detects deviations from a set point and triggers corrective effector responses to reverse the change.
`intermediate`	Give a physiological example of a positive feedback loop in human biology.	Oxytocin release during childbirth, where uterine contractions stimulate cervical stretch, triggering greater oxytocin secretion until delivery.
`intermediate`	What are the four essential postulates of Charles Darwin's theory of evolution by natural selection?	1. Individuals within populations exhibit phenotypic variation. 2. Some variations are heritable. 3. More offspring are produced than can survive. 4. Individuals with favorable traits survive and reproduce more successfully.
`intermediate`	How do homologous structures differ from analogous structures in comparative anatomy?	Homologous structures share common ancestral origin but may differ in function (e.g., human arm and bat wing); analogous structures perform similar functions but evolved independently via convergent evolution (e.g., bird wing and insect wing).
`advanced`	What is the Central Dogma of Molecular Biology, and what notable enzyme constitutes an exception to its classical flow?	DNA is transcribed into RNA, which is translated into protein; reverse transcriptase (present in retroviruses) synthesizes complementary DNA (cDNA) from an RNA molecule.
`advanced`	Which subunit of bacterial RNA polymerase holoenzyme recognizes promoter elements (-10 Pribnow and -35 boxes)?	The sigma factor (e.g., sigma-70).
`advanced`	What are the primary differences between innate and adaptive immunity regarding response speed, specificity, and immunological memory?	Innate immunity acts immediately (minutes/hours), uses broad non-specific pattern receptors, and lacks memory; adaptive immunity takes days to develop, is highly antigen-specific, and generates long-lived immunological memory.
`advanced`	What receptors on innate immune cells recognize Pathogen-Associated Molecular Patterns (PAMPs) such as lipopolysaccharide (LPS)?	Pattern Recognition Receptors (PRRs), prominently including Toll-Like Receptors (TLRs, e.g., TLR4 for LPS).
