本手册汇编了九年级CCEA生物所需的基本公式、方程式和关键生物学原理，适用于考试前快速复习。
1. Photosynthesis Equation | 光合作用方程式
Photosynthesis is the process by which green plants use light energy to convert carbon dioxide and water into glucose and oxygen. This process occurs in chloroplasts and requires chlorophyll.
光合作用是绿色植物利用光能将二氧化碳和水转化为葡萄糖和氧气的过程。这一过程发生在叶绿体中并需要叶绿素。
The word equation summarises the reactants and products:
文字方程式概括了反应物和产物：
Carbon dioxide + Water → Glucose + Oxygen
二氧化碳 + 水 → 葡萄糖 + 氧气
The balanced chemical equation shows that six molecules of carbon dioxide and six molecules of water yield one molecule of glucose and six molecules of oxygen.
平衡化学方程式表明，六分子二氧化碳和六分子水生成一分子葡萄糖和六分子氧气。
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
2. Aerobic Respiration Equation | 有氧呼吸方程式
Aerobic respiration occurs in the mitochondria of cells and releases energy from glucose using oxygen. Carbon dioxide and water are produced as waste products.
有氧呼吸发生在细胞的线粒体中，利用氧气从葡萄糖中释放能量。二氧化碳和水作为废物产生。
The word equation for aerobic respiration is:
有氧呼吸的文字方程式为：
Glucose + Oxygen → Carbon dioxide + Water + Energy (ATP)
葡萄糖 + 氧气 → 二氧化碳 + 水 + 能量 (ATP)
The balanced chemical equation mirrors photosynthesis in reverse, releasing energy stored in glucose.
平衡化学方程式与光合作用互为逆反应，释放储存在葡萄糖中的能量。
