: : 39 How did researchers confirm their theory about the remarkable effect of
: : sugar?
: : (A)They stopped feeding both groups of mice any more sugar.
: : (B)They found that both groups of mice lost interest in the sweet food.
: : (C)They gave both groups of mice a drug that blocks the release of
: : beta-endorphins.
: : (D)They measured the amount of beta-endorphins released in the blood of the
: : mice.
: : 答案是C
: : 依據題目,研究人員用來驗證假設的藥,明明是阻斷受器,而並非停止製造
: : beta-endorphin,所以答案(C)是絕對錯誤:
: : Researchers confirmed their theory by giving both groups of mice Naltrexone,
: : a drug that blocks beta-endorphin receptors.
: c沒錯吧...
: 你仔細看清楚c後面說的是blocks the release of beta-endorphins
: 意思是隔絕beta-endorphins的釋放
: 原文是說隔絕接受器官的功能 使它不能接受到beta-endorphins
: 為什麼你會覺得有問題?因為隔絕是兩面的...
: 你隔絕a釋放 同時不是也隔絕了b接受嗎?
: c只是換個說法而已..
: 如果今天它本文是寫disable 那c可能就有問題了
Naltrexone是beta-endorphins的拮抗劑,
是因為結構類似beta-endorphins故可與其競爭在神經細胞上的受器,
是故該藥物並不影響beta-endorphins的釋放。
答案C說該藥物隔絕beta-endorphins的釋放是不正確的說法,
事實上老鼠體內的beta-endorphins反而可能因為該藥物的補償效應而增加釋放,
但無論分泌多少beta-endorphins,都會因為Naltrexone而無法發揮原有的功能...
簡單的說Naltrexone是讓endorphin沒有功用,而非讓endorphin不會產生。
所謂"隔絕是兩面的"是不嚴謹的說法,
你隔絕了beta-endorphins的釋放,但並沒有隔絕了其接受,
receptor是因為接收了Naltrexone所以無法接收beta-endorphins。
所以我認為本題答案C也是錯的。
