真题 Paper 1(中文)

本试卷共設36题。
試卷內的插圖未必依照比例繪成。
1. 以下哪個過程涉及附在細胞膜上的酶?
A. 肺部二氧化碳的排泄
B. 沿着木質導管的水平運輸
C. 植物細胞葉緣體內的卡爾文循環
D. 小腸內碳水化合物的消化

指示：參考以下有關過氧化氫酶的實驗，解答第2至4題。該酶催化過氧化氫的分解，然後釋放氧氣。志光將一個1cm²的猪肝立方體放置在盛有5mL過氧化氫溶液的燒管內。他利用有餘烬的木條來測試釋出的氣體。他再用牛肉、馬鈴薯和蘋果重複實驗。結果如下所示：

组織	氧泡釋出的速率	使有餘烬的木條重燃
猪肝	普通	是
牛肉	普通	是
馬鈴薯	缓慢	是
蘋果	缓慢	是

1. 以下哪項陳述是實驗的觀察？
   A. 這些組織含過氧化氫酶。
   B. 反應釋出氧氣。
   C. 釋出的氣體使有餘烬的木條重燃。
   D. 動物組織較植物組織有更多過氧化氫酶。

2. 將當氣泡的釋出停止時，志光將更多的過氧化氫溶液加入燒管。以下哪項组合正確顯示這個額外實驗的預期結果及其解釋？
   预期结果 解释
   A. 有氣泡釋出 過氧化氫酶的作用是專一的。
   B. 有氣泡釋出 過氧化氫酶是可再用的。
   C. 没有氣泡 過氧化氫酶已耗盡。
   D. 没有氣泡 過氧化氫酶已墊性。

3. 為了證明過氧化氫酶是這個酵反應的受質，應進行以下哪個步驟作為對照？
   A. 用水和组纖重復實驗。
   B. 用水和經煮沸的组纖重復實驗。
   C. 只用過氧化氫而不加人组纖重復實驗。
   D. 用過氧化氫和經煮沸的组纖重復實驗。

真题 Paper 2(中文)

甲部
人体生理學：調節與控制
回答本部分内的所有試題。

1(a) 在一项研究飲用不同液體對產生尿液的效果中，將健康人士分為三組，進行相同類型活動和食用相同的膳食。然後，A 組喝 1500 mL 含酒精飲品；B 組喝 1500 mL 水；C 組沒有喝任何液體。每隔 60 分鐘收集尿液並量度尿液體積，為時 240 分鐘。實驗結果如下圖所示：

例： - A 組：每人飲用 1500 mL 含酒精飲品 - B 組：每人飲用 1500 mL 水 - C 組：沒有飲用任何液體

(i) 參考激素對滲透調節的控制，解釋為什麼 C 組人士產生的平均尿液體積較 A 組和B 組人士的低。

(ii) (1) 參考 A 組與 B 組的結果，指出飲用含酒精飲品對尿液產生的整體效應。 (2) 根據 (ii)(1)，推斷酒精在激素對滲透調節的控制方面可能產生的一種效應。

(iii) 解釋為什麼參與者需避免在研究期間進行劇烈活動。
