📚 AS Eduqas Biology: Vocabulary & Terminology Memorisation Guide | AS Eduqas 生物：词汇术语速记指南
Mastering the language of biology is half the battle in AS Eduqas. This guide turns tricky terms into memorable hooks using etymology, analogies, and mnemonics, so you can recall precise definitions under pressure.
在 AS Eduqas 生物中，掌握学科语言就是成功的一半。本指南利用词源、类比和助记符，将难记的术语转化为难忘的挂钩，让你在考试压力下也能准确回忆定义。
1. Why Master Biological Terminology? | 为何要掌握生物学术语？
Examiners reward precise language. Writing 'the substrate fits into the enzyme’s active site like a key in a lock' earns marks, whereas 'the stuff goes into the enzyme' loses them. Terminology is your toolkit for explaining complex processes succinctly.
考官奖励精准的语言。写出“底物像钥匙插入锁一样嵌入酶的活性位点”能得分，而“东西进入酶”则会丢分。术语是你简洁解释复杂过程的工具箱。
Many AS questions test definitions directly—'Define the term osmosis' or 'Explain what is meant by a homologous chromosome pair'. Having a rapid recall system turns these into easy marks.
许多 AS 题目直接考查定义——“定义渗透作用”或“解释同源染色体对的含义”。拥有快速回忆系统可以将这些题目变成送分题。
2. The Power of Root Words | 词根的力量
Biology builds its vocabulary from Latin and Greek roots. Once you recognise common prefixes and suffixes, you can decode unfamiliar terms—for instance, 'hypertonic' simply means 'hyper-' (over) + 'tonos' (tension).
生物学的词汇建立在拉丁语和希腊语词根之上。一旦你认识常见的前缀和后缀，就能破解陌生术语——例如，“hypertonic”仅仅是“hyper-”（过度）+“tonos”（张力）。
Use this table to spot patterns across the specification:
利用下表发现考试大纲中的规律：
| Prefix/Suffix | Meaning | Example |
|---|---|---|
| endo- | inside | endocytosis (taking into cell) |
| exo- | outside | exocytosis (exit from cell) |
| glyco- | sugar | glycoprotein |
| -ase | enzyme | amylase, polymerase |
| -ose | sugar | glucose, sucrose |
| haplo- | single | haploid (one set of chromosomes) |
| diplo- | double | diploid (two sets) |
中文翻译对照：endo- 内；exo- 外；glyco- 糖；-ase 酶；-ose 糖；haplo- 单；diplo- 双。
3. Carbohydrates and Lipids | 碳水化合物与脂类
Remember 'monosaccharide' as 'one sugar'. Link it to 'mono' (one) and '-saccharide' (sugar). Glucose is a hexose: 'hex' = six, 'ose' = sugar → six-carbon sugar. This pattern helps with triose, pentose, hexose.
将“monosaccharide”记为“一个糖”。将其与“mono-”（一）和“-saccharide”（糖）联系起来。葡萄糖是一种己糖：“hex”= 六，“ose”= 糖 → 六碳糖。同样的规律可用于三碳糖、五碳糖和己糖。
Glycosidic bond: think 'glyco' (sugar) + 'side' (two sides joined). Visualise two monosaccharides joining hands through a covalent bond formed by condensation.
糖苷键：想象“glyco”（糖）+“side”（两侧相连）。将两个单糖通过缩合反应形成的共价键想象成两人握手。
Triglyceride: 'tri-' (three) + 'glycerol' backbone. It fuses three fatty acid chains—picture a glycerol 'coat rack' with three fatty acid 'hooks'.
甘油三酯：“tri-”（三）+ 甘油骨架。它结合了三条脂肪酸链——将甘油想象成一个衣帽架，上面挂着三条脂肪酸“挂钩”。
4. Proteins and Enzymes | 蛋白质与酶
Peptide bond: think 'peptide' sounds like 'pept-ide'—a link between amino acids. 'Dipeptide' = two amino acids; 'polypeptide' . The bond forms between the amine group (NH₂) and carboxyl group (COOH) via condensation.
肽键：可以将“peptide”想成“pept-ide”——氨基酸之间的连接。“Dipeptide”=两个氨基酸；“polypeptide”=多个。键是通过缩合反应在氨基 (NH₂) 和羧基 (COOH) 之间形成的。
Lock and key model: the 'key' is the substrate, the 'lock' is the enzyme’s active site. Induced fit model: imagine a handshake—the hand (enzyme) adjusts slightly to grip the key (substrate) more tightly.
锁钥模型：“钥匙”是底物，“锁”是酶的活性位点。诱导契合模型：想象一次握手——手（酶）会微调姿势以更紧地抓住钥匙（底物）。
Competitive inhibitor: 'competes' for the active site, like a rival taking your parking spot. Non-competitive inhibitor: attaches elsewhere, changing the shape of the active site so the substrate cannot bind, like a dent on a lock.
竞争性抑制剂：“竞争”活性位点，就像对手占你的停车位。非竞争性抑制剂：附着在其他位置，改变活性位点形状，使底物无法结合，就像锁上有了一个凹痕。
5. Nucleic Acids | 核酸
DNA structure is a double helix: 'double' = two strands, 'helix' = spiral staircase. Remember base pairing by 'A and T have two hydrogen bonds, C and G have three'. A phrase like 'Apples in the Tree, Car in the Garage' can help—though focus on AT having 2, CG 3.
DNA 结构是双螺旋：“double”=两条链，“helix”=螺旋楼梯。用“A 与 T 有两个氢键，C 与 G 有三个氢键”记住碱基配对。可以想成“苹果在树上(A-T)，汽车在车库(C-G)”，重点 A-T 有 2 个键，C-G 有 3 个。
Phosphodiester bond: 'phospho-' (phosphate group) + '-diester' (two ester links). It connects the sugar of one nucleotide to the phosphate of the next, building the backbone.
磷酸二酯键：“phospho-”（磷酸基团）+“-diester”（两个酯键）。它将一个核苷酸的糖与下一个核苷酸的磷酸连接起来，构建了骨架。
RNA uses uracil instead of thymine. Think 'U replace T' in RNA, so A pairs with U.
RNA 用尿嘧啶代替胸腺嘧啶。记住“在 RNA 里 U 换掉 T”，所以 A 与 U 配对。
6. Cell Structure | 细胞结构
Mitochondria: the 'mighty' powerhouse. The inner membrane is highly folded into cristae to increase surface area for respiration. 'Cristae' sounds like 'creases'—folds.
线粒体：细胞“动力”工厂。内膜高度折叠成嵴，以增加呼吸作用的表面积。“Cristae”听起来像“creases”（褶皱）。
Ribosomes: 'ribo-nucleic acid + some'—they are made of rRNA and protein. The 80S ribosome (eukaryotic) vs 70S (prokaryotic). Remember 'Eukaryotes are higher, so 80'—larger S value.
核糖体：由 rRNA 和蛋白质构成。“80S”（真核）对比“70S”（原核），可以记住“真核生物更高级，所以 80”。
Lysosome: 'lyso' (breakdown) + 'some' (body). It contains hydrolytic enzymes that digest worn-out organelles and engulfed materials.
溶酶体：“lyso”（分解）+“some”（体）。它含有水解酶，能消化衰老细胞器和被吞噬的物质。
7. Cell Membranes and Transport | 细胞膜与运输
Fluid mosaic model: 'fluid' because phospholipids move laterally; 'mosaic' because proteins and other molecules are dotted in a pattern. Think of a sea of lipids with icebergs (proteins) floating.
流动镶嵌模型：“流动”因为磷脂可以侧向移动；“镶嵌”因为蛋白质和其他分子像马赛克一样分布。想象一片脂质海洋，上面漂浮着蛋白质冰山。
Osmosis is specifically the net movement of water through a selectively permeable membrane from a region of higher water potential to lower water potential. Mnemonic: 'Only Squirrels Make Intelligent Special Nuts'—hopelessly silly, but you can create your own; the key is linking 'osmosis' to 'water'.
渗透作用是水通过选择性通透膜从水势较高的区域净移动到水势较低的区域。记忆提示：将“osmosis”与“water only”挂钩——Osmosis 唯独指水。
Endocytosis: 'endo' (in) + 'cyto' (cell) + 'sis' (process) — intake by the cell. Exocytosis: exit. Phagocytosis: 'phago' (eating) — cell eating.
胞吞作用：“endo”（内）+“cyto”（细胞）+“sis”（过程）——细胞摄取。胞吐作用：出去。吞噬作用：“phago”（吃）——细胞吞噬。
8. Cell Division and Basic Genetics | 细胞分裂与基础遗传学
Mitosis produces two genetically identical daughter cells for growth and repair. The phases: Prophase, Metaphase, Anaphase, Telophase — remember 'PMAT'. Add 'C' for cytokinesis: 'Pass Me Another Taco, Chief'.
有丝分裂产生两个基因相同的子细胞，用于生长和修复。阶段：前期、中期、后期、末期——记住“PMAT”。加上胞质分裂(C)：可以记为“请给我另一个卷饼，首领”。
Homologous chromosomes: 'homo' (same) chromosomes pair up—same size, same genes, but may have different alleles. Homozygous: 'homo' (same) + 'zygous' (joined) — two identical alleles for a trait.
同源染色体：“homo”（相同）染色体配对——大小相同、基因相同，但可能携带不同的等位基因。纯合子：“homo”（相同）+“zygous”（结合）——一个性状的两个等位基因相同。
Genotype is the genetic makeup; phenotype is the observable characteristic. Remember: 'Geno' like 'gene archive' stored inside; 'Pheno' like 'phenomenon' you can see.
基因型是遗传组成；表型是可观察的特征。记住：“Geno”像内部存储的“基因档案”；“Pheno”像你可以看到的“现象”。
9. Classification and Biodiversity | 分类与生物多样性
The hierarchical classification order: Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species. Mnemonic: 'Dear King Philip Came Over For Good Soup'.
阶层分类顺序：域、界、门、纲、目、科、属、种。记忆口诀：“Dear King Philip Came Over For Good Soup”（亲爱的菲利普国王来喝美味汤）。
Binomial name consists of Genus (capitalised) and species (lowercase), e.g., Homo sapiens. The genus groups closely related species. It's the 'family name' in the biological world.
双名法由属名（首字母大写）和种加词（小写）组成，例如 Homo sapiens。属将亲缘关系近的物种归在一起，相当于生物世界的“姓氏”。
Biodiversity includes species richness and genetic diversity. Species evenness is often tested: a habitat with equal numbers of each species has high evenness. Think 'even distribution'.
生物多样性包括物种丰富度和遗传多样性。物种均匀度常被考查：各个物种个体数相等的栖息地具有高均匀度。想象“平均分配”。
10. Gas Exchange and Transport Terms | 气体交换与运输术语
Countercurrent flow: water and blood flow in opposite directions across the gill lamellae to maintain a concentration gradient. 'Contra' means against—currents run contrary. It maximises oxygen extraction.
逆流交换：水流和血液在鳃瓣上以相反方向流动，以维持浓度梯度。“Contra”意为相反——水流和血流反向而行，从而最大化氧气摄取。
Tracheae: insect air tubes with rings of chitin that keep them open. 'Trachea' sounds like 'track'—a tunnel for air. Spiracles: small openings on the insect body surface. Think 'spir-acle' like 'air-acle' for air.
气管：昆虫体内的空气管道，带有几丁质环以保持通畅。“Trachea”像“track”（轨道）——空气的隧道。气门：昆虫体表的小开口。联想“spir-acle”像是“air-acle”。
Atrioventricular valve (AV): between atrium and ventricle. 'Atrio' to 'ventricle'—blood flows one way. The bicuspid valve is on the left side, tricuspid on the right. Remember: 'tri' (three flaps) is on the right; people 'try' to be right.
房室瓣 (AV)：位于心房和心室之间。血液单向流动。二尖瓣在左侧，三尖瓣在右侧。记住：“tri”（三个瓣）在右边；人总“try”要做得对（右）。
11. Mnemonics and Memory Palace for Biology | 生物学的助记符与记忆宫殿
Create vivid mental images for abstract processes. For the light-dependent reaction, picture photosystem II as a 'bucket' receiving light and splitting water, sending electrons down a 'ski slope' (electron transport chain) while hydrogen ions are pumped into a 'reservoir' (thylakoid space).
为抽象过程创造生动的心理图像。对光依赖反应，可以把光系统 II 想象成一个接收光的“桶”，分解水，并将电子发送下“滑雪坡”（电子传递链），同时将氢离子泵入“水库”（类囊体空间）。
For memorising the order of glycolysis intermediates, use a silly sentence like 'Goodness Gracious, Father Franklin Did Go Buy Pretty Pumpkins' to recall Glucose, Glucose-6-phosphate, Fructose-6-phosphate, etc. Adjust for your syllabus needs.
为了记住糖酵解的中间产物顺序，可以使用一个荒诞的句子，如“Goodness Gracious, Father Franklin Did Go Buy Pretty Pumpkins”来回忆葡萄糖、6-磷酸葡萄糖等。可根据大纲需要自行改编。
12. Active Recall and Common Pitfalls | 主动回忆与常见陷阱
Don't confuse 'hypertonic' with 'hypotonic' solute concentration (water enters). Picture a hyper child with high energy; hypertonic has high solutes.
不要混淆“hypertonic”和“hypotonic”。Hyper- = 溶质浓度高（水离开细胞），hypo- = 溶质浓度低（水进入细胞）。想象一个 hyper 躁动的孩子精力旺盛；高渗意味着高溶质。
Be precise: 'mitosis produces two identical nuclei', but cytokinesis divides the cytoplasm. Many students write 'mitosis divides the cell'—strictly speaking, mitosis is nuclear division.
用词要精确：“有丝分裂产生两个相同的细胞核”，但胞质分裂才分离细胞质。许多学生写“有丝分裂使细胞分裂”——严格来说，有丝分裂是细胞核分裂。
Practice defining terms aloud and drawing labelled diagrams from memory. Use this guide side by side with your specification to self-test every term until you can explain it in one breath.
大声口头定义术语，并凭记忆画出带标签的图示。将本指南与考纲对照，自我测试每个术语，直到你能一口气解释清楚为止。
