1. Cell Structures & Organelles | 细胞结构与细胞器
The cell is the basic unit of life. To remember the organelles, think of a factory: nucleus as the control room, mitochondria as power stations, ribosomes as protein assembly lines.
细胞是生命的基本单位。为了记住细胞器，可以把细胞想象成工厂：细胞核是控制室，线粒体是发电站，核糖体是蛋白质组装线。
Nucleus – ‘kernel’ or ‘center’; contains genetic material (DNA) that instructs the cell. Mnemonic: ‘New-clear-us’ – think of a clear capsule with instructions inside.
细胞核 – “核心”；含有指导细胞的遗传物质（DNA）。记忆法：联想“核”心里面有指令。
Mitochondria – ‘mighty’ energy producers; singular is ‘mitochondrion’. Remember “Mighty Kraft” generating ATP energy, like a Kraft factory.
线粒体 – “强力”能量生产者；单数为 mitochondrion。联想“Mighty（强大）”的能量工厂，制造 ATP。
Ribosomes – tiny dots that assemble amino acids into proteins. Think of ‘ribo-some’ as ‘ribosome = ribo (like ribonucleic) + soma (body)’—protein-making bodies.
核糖体 – 将氨基酸组装成蛋白质的微小颗粒。联想“核糖体”是制造蛋白质的“小体”。
Cell membrane – semi-permeable barrier made of phospholipids. Imagine a ‘gatekeeper’ deciding what enters or leaves.
细胞膜 – 由磷脂双分子层构成的半透屏障。想象一位“守门人”决定进出。
Chloroplast – green organelle containing chlorophyll for photosynthesis. ‘Chloro’ = green, ‘plast’ = particle. Picture a green solar panel.
叶绿体 – 含叶绿素进行光合作用的绿色细胞器。“chloro”意为绿，“plast”意为颗粒。想象一块绿色太阳能板。
Permanent vacuole – large sac in plant cells filled with cell sap; helps maintain turgor. Think of a water balloon pushing against the cell wall.
中央大液泡 – 植物细胞中充满细胞液的大囊，维持膨压。想象一个水气球撑起细胞壁。
2. Transport in Cells | 细胞运输
Three key processes govern movement of substances across cell membranes: diffusion, osmosis, and active transport. Each has a distinct driving force.
三个关键过程支配着物质跨膜运动：扩散、渗透和主动运输。它们各有不同的驱动力。
Diffusion – net movement of particles from high to low concentration, down a gradient. Mnemonic: ‘D’ for ‘Downhill’ – particles move downhill without energy (passive).
扩散 – 粒子沿浓度梯度从高浓度向低浓度的净运动，不耗能。记忆：“扩”散就是“扩散开来”，像香水味道飘散。
Osmosis – diffusion of water across a partially permeable membrane. Think ‘Osmosis is water’s special diffusion.’ Use ‘OH’ to link water (H₂O) and osmosis.
渗透 – 水分子通过半透膜的扩散。联想“渗”水，渗透是水的专属扩散。
Active Transport – requires energy (ATP) to move substances against the concentration gradient. ‘Active’ implies using energy, like swimming against a current.
主动运输 – 需要能量（ATP）逆浓度梯度运输物质。“主动”意味着耗能，如同逆流而上。
Easy recall mantra: “Diffusion = Downhill, Osmosis = Only water, Active = Against the flow.” Keep this D-O-A mantra.
速记口诀：“扩散顺坡走，渗透只走水，主动逆流游。”记住“顺、只、逆”三字诀。
3. Enzymes & Digestion | 酶与消化
Enzymes are biological catalysts that speed up reactions by lowering activation energy. Their shape is specific to a substrate – like a lock and key.
酶是生物催化剂，通过降低活化能加速反应。它们与底物的形状特异性结合，犹如锁与钥匙。
Carbohydrase (amylase) – breaks starch into sugars. Think: ‘Carb’ cutter.
碳水化合物酶（淀粉酶） – 将淀粉分解为糖。记“碳水切割器”。
Protease – breaks proteins into amino acids. ‘Protease’ sounds like ‘protein-ace’.
蛋白酶 – 将蛋白质分解为氨基酸。“蛋白酶”就是蛋白质的“王牌”分解剂。
Lipase – breaks lipids (fats) into glycerol and fatty acids. ‘Lip’ means fat (like liposuction).
脂肪酶 – 将脂肪分解为甘油和脂肪酸。“lip”表示脂肪（如吸脂手术 liposuction）。
Denaturation occurs at extreme pH or heat; the active site loses shape, stopping function. Mnemonic: ‘De-nature’ the enzyme destroys its nature.
变性发生在极端pH或高温；活性部位变形，功能丧失。联想“变性”即改变其本性。
4. Respiration & Energy | 呼吸与能量
cess of releasing energy from glucose, occurring in every living cell. It is not breathing! Remember ‘respiration = energy release’.
呼吸作用是细胞从葡萄糖中释放能量的过程，不是普通的呼吸。记住：呼吸作用 = 释放能量。
Aerobic respiration: C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + energy (ATP). ‘Aerobic’ = with air (oxygen). Link ‘aero’ to air.
有氧呼吸： C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + 能量（ATP）。aero 意为空气，有氧需要氧气。
Anaerobic respiration in animals produces lactic acid, causing muscle fatigue. In plants/yeast, ethanol + CO₂. ‘Anaerobic’ = without air. Think ‘an-aerobic’ – no oxygen.
无氧呼吸在动物中产生乳酸，导致肌肉疲劳；在植物和酵母中产生乙醇和CO₂。Anaerobic = 缺少空气。联想“an-”否定，“aerobic” 氧气。
Recall: “With O₂ → CO₂ + H₂O; Without O₂ → Lactic acid (animals) or Ethanol (yeast).”
记住：“有氧产水碳，无氧动物乳酸，酵母酒精加碳。”
5. Photosynthesis | 光合作用
ight energy into chemical energy in the form of glucose, within chloroplasts. Word origin: ‘photo’ = light, ‘synthesis’ = putting together.
光合作用在叶绿体中将光能转化为化学能，以葡萄糖形式储存。“photo”指光，“synthesis”意为合成。
Equation: 6CO₂ + 6H₂O → (light, chlorophyll) → C₆H₁₂O₆ + 6O₂. Remember “Carbon dioxide + Water → Sugar and Oxygen” with sun energy.
方程式：6CO₂ + 6H₂O →（光、叶绿素）→ C₆H₁₂O₆ + 6O₂。记住：二氧化碳加水，光叶绿素下，生成葡萄糖和氧。
Limiting factors: Light intensity, CO₂ concentration, Temperature – remember LCT. Whichever is lowest limits the rate.
限制因素：光照强度、二氧化碳浓度、温度 – 记“光碳温”。哪个最低，速率就受限于它。
6. Circulatory System | 循环系统
circulatory system transports substances around the body: heart, blood vessels, blood. Use ‘o’ = heart. Arteries carry blood Away from the heart (A for Away); Veins carry blood back.
循环系统负责运输：心脏、血管、血液。Cardio 表示心脏。动脉（Artery）将血液从心脏运走（A为离开）；静脉（Vein）将血液送回。
Artery – lar, elastic, carrying high-pressure oxygenated blood (except pulmonary artery). Mnemonic: “Artery = Away, thick wall.”
动脉 – 壁厚、有弹性，输送高压富氧血（肺动脉除外）。记忆：“动脉离开，壁厚抗压。”
Vein – thinner walls, have valves to prevent backflow. “Vein = Visit the heart, valves vital.”
静脉 – 壁薄，有静脉瓣防止倒流。“静脉回心，瓣膜防逆。”
Capillary – one-cell thick for exchange of substances. ‘Cap’ like a tiny cap touching cells.
毛细血管 – 仅单层细胞，利于物质交换。“cap”像微小的帽子，紧密接触组织。
Red blood cells (erythrocytes) – no nucleus, biconcave, carry oxygen via haemoglobin. ‘Erythro’ = red, ‘cyte’ = cell.
红细胞 – 无核，双凹圆盘状，通过血红蛋白携带氧气。“Erythro”意为红，“cyte”意为细胞。
White blood cells (leukocytes) – part of immune system, engulf pathogens or produce antibodies. ‘Leuko’ = white.
白细胞 – 免疫系统一部分，吞噬病原体或产生抗体。“Leuko”意为白。
Platelets – small cell fragments for clotting. ‘Plate’ = flat piece, think of plates patching a wound.
血小板 – 细胞碎片，参与凝血。形象为“小板”修补伤口。
7. Nervous System | 神经系统
lus → receptor → sensory neuron → relay neuron (CNS) → motor neuron → effector → response.
神经系统通过电冲动协调反应。关键细胞：神经元。反射弧：刺激→感受器→感觉神经元→中间神经元（中枢）→运动神经元→效应器→反应。
Mnemonic for reflex arc: “Silly Rabbits Sing Really Madly Every Evening” – Stimulus, Receptor, Sensory, Relay, Motor, Effector.
反射弧口诀：“小兔感兴中运效” – 刺激、感受器、感觉神经元、中间神经元、运动神经元、效应器。
