IB DP Biology Objective B3.2.15 Heart Structure Revision Can be used for learning, revision or retrieval. Full objective: B3.2.15(HL) Adaptations of the mammalian heart for delivering pressurised blood to the arteries: include form-function adaptations of these structures: cardiac muscle, pacemaker, atria, ventricles, atrioventricular and semilunar valves, septum and coronary vessels. Be able to identify these features on a diagram of the heart in the frontal plane and trace the unidirectional flow of blood from named veins to arteries.

IB DP HL Biology All of B3.2 objectives A3 Revision Summary WORD (for editing) and PDF files

IB DP HL Biology Objectives: B2.3.6 and B2.3.7 A3 Revision Summary WORD (for editing) and PDF files. B2.3.6 Surface area-to-volume ratios and constraints on cell size: understand the mathematical ratio between volume and surface area and that exchange of materials across a cell surface depends on its area whereas the need for exchange depends on cell volume. B2.3.7 (HL) Adaptations to increase surface area-to-volume ratios of cells: include flattening of cells, microvilli, and invagination. Use erythrocytes and proximal convoluted tubule cells in the nephron as examples.

IB DP HL Biology Objectives: C1.1.13(HL), C1.1.15(HL), C1.1.16(HL) - objectives that students want to revise. A3 Revision Summary WORD (for editing) and PDF files Full objective statements: C1.1.13(HL) Cyclical and linear pathways in metabolism: use glycolysis, the Krebs Cycle and the Calvin cycle as examples. C1.1.15(HL) Competitive inhibition as a consequence of an inhibitor binding reversibly to an active site: use statins as an example of competitive inhibitors. Include the difference between competitive and non-competitive inhibition in the interaction between substrate and inhibitor and therefor the effect of substrate concentration. C1.1.16(HL) Regulation of metabolic pathways by feedback inhibition: use the pathway that produces isoleucine as an example of an end product acting as an inhibitor.

IB DP HL Biology Objectives: B2.2.2, B2.2.4 and B2.2.6(HL) A3. Revision Summary Blank student copy and with teaching notes WORD (for editing) and PDF files Full objective statements: B2.2.2 Advantage of the separation of the nucleus and cytoplasm into separate compartments: limit to separation of the activities of gene transcription and translation – post-transcriptional modification of mRNA can happen before the mRNA meets ribosomes in the cytoplasm. B2.2.4 (HL) Adaptations of the mitochondrion for production of ATP by aerobic cell respiration: including: a double membrane with a small volume of intermembrane space, large surface area of cristae and compartmentalisation of enzymes and substrates of the Kreb cycle in the matrix. In prokaryotes this is not possible – mRNA may immediately meet ribosomes. B2.2.6 (HL) Functional benefits of the double membrane of the nucleus: include the need for pores in the nuclear membrane and for the nuclear membrane to break into vesicles during mitosis and meiosis.

IB DP Biology Objective A1.2.6: Structure of DNA Purpose: retrieval practice/ revision. Can be used after the teaching of DNA structure to see what students remember. Full objective: A1.2.6 DNA as a double helix made of two antiparallel strands of nucleotides with two strands linked by hydrogen bonding between complementary base pairs: in diagrams of DNA structure, students should draw the two strands antiparallel, but are not required to draw the helical shape. Students should show adenine (A) paired with thymine (T), and guanine (G) paired with cytosine ©. Students are not required to memorise the relative lengths of purine and pyrimidines bases, or number of hydrogen bonds.

IB DP Biology A3. Revision Summary covering all objectives in D1.2 Transcription Student favourite for quick recall before assessments and exams

IB DP Biology A1.1 Water Retrieval Practice - quick recall/ retrieval at start of lesson after polarity of water has been taught. WORD (for editing) and PDF Student handout and teaching answers.

IB DP Biology B1.1.4 Form and Function of Monosaccharides Reaching comprehension created on DIFFIT. Covers objective: B1.1.4 Form and function of monosaccharides: recognise pentoses and hexoses as monosaccharides from molecular diagrams showing them in the ring forms. Use glucose as an example of the link between the properties of a monosaccharide and how it is used, emphasising solubility, transportability, chemical stability and the yield of energy from oxidation properties.
