詞性:名詞
1. 意思:拮抗劑;拮抗物;對(duì)抗者

3. 用法:
(1)作為名詞,agonist指的是一種藥物或化學(xué)物質(zhì),能夠與特定的受體結(jié)合,并產(chǎn)生生理作用。它們可以刺激或阻斷受體,從而影響神經(jīng)遞質(zhì)的釋放和細(xì)胞信號(hào)傳導(dǎo)。
(2)在生理學(xué)中,agonist也可以指某個(gè)肌肉或肌肉群,它們會(huì)與另一個(gè)肌肉產(chǎn)生對(duì)抗性收縮。
4. 例句:
(1)The drug acts as an agonist, binding to the receptor and stimulating its activity.

(2)The athlete's muscles were fatigued after hours of training, but he pushed through the pain with the help of agonist muscles.

(5)Some athletes use performance-enhancing drugs that act as agonists to improve their physical abilities.
一些運(yùn)動(dòng)員使用能夠提升身體能力的,它們起著拮抗劑的作用。
5. 同義詞及用法:
agonist與antagonist是相對(duì)的概念,它們分別指對(duì)抗性和拮抗性。因此,agonist的同義詞可以是antagonist。此外,還有以下幾個(gè)同義詞:
(1)antagonistic:形容詞,意為“對(duì)抗性的”、“敵對(duì)的”,常用來(lái)形容人或事物之間存在的或競(jìng)爭(zhēng)關(guān)系。
例句:The two teams were antagonistic towards each other, constantly trying to outdo one another.
(2)opponent:名詞,意為“敵手”、“反對(duì)者”,指與某人或某事物相對(duì)立的人或事物。
例句:The two candidates were opponents in the election, each trying to win the support of the voters.
這兩位候選人在中是對(duì)手,每個(gè)人都試圖贏得選民的支持。
(3)adversary:名詞,意為“對(duì)手”、“敵人”,指與某人或某事物發(fā)生或競(jìng)爭(zhēng)的對(duì)手。
例句:The two companies were fierce adversaries in the market, constantly trying to gain a competitive edge.
這兩家公司在市場(chǎng)上是激烈的對(duì)手,不斷試圖獲得競(jìng)爭(zhēng)優(yōu)勢(shì)。
6. 編輯總結(jié):
agonist一詞通常用來(lái)指藥物、化學(xué)物質(zhì)或肌肉,在生理學(xué)和醫(yī)學(xué)領(lǐng)域有著重要的作用。它與antagonist相對(duì)應(yīng),可用來(lái)形容、競(jìng)爭(zhēng)或敵對(duì)關(guān)系。同時(shí),它也可以引申出比喻意義,指代任何起著拮抗作用的事物。掌握agonist一詞的含義和用法,能夠更好地理解相關(guān)領(lǐng)域的知識(shí),并且在日常交流中更準(zhǔn)確地表達(dá)自己的想法。
