- It is highlighted that besides passive transport, dissolved metal transport into bivalves was involved in active transport coupled with ATP. 強調了貝類(lèi)對溶解態(tài)重金屬的轉運除了被動(dòng)轉運之外，還涉及到需要ATP供能的主動(dòng)轉運過(guò)程。
- Anything that interferes with the provision of energy will interfere with active transport. 任何能夠影響到能量供應的因素都能影響到主動(dòng)運輸。

- The uplifting of the basement made the cover favorable for the secondary activation and reworking, and epigenetic metallogenic process was developed. 基底的抬升使蓋層具備了次生活化改造條件，蓋層中發(fā)育明顯的后生鈾成礦作用。
- Active transport appears to be limited to drugs structurally similar to endogenous substances. 主動(dòng)轉運似乎只限于其結構類(lèi)似于機體內源性物質(zhì)的那些藥物。
- Active transport processes have been identified for various ions, vitamins, sugars, and amino acids. 現已確認，多種離子、維生素類(lèi)、糖類(lèi)和氨基酸類(lèi)都采取這種主動(dòng)轉運方式。
- My question is: Why was official business discharged as a secondary activity formerly? And what is the primary activity? 為什么從前的機關(guān)事務(wù)是作為次要工作執行的?那首要的工作是什么呢?

- Drugs may cross a biologic barrier by passive diffusion, facilitated passive diffusion, active transport, or pinocytosis. 藥物可通過(guò)被動(dòng)擴散、易化被動(dòng)擴散、主動(dòng)轉運或胞飲作用等方式穿越生物屏障。
- Active transport : This process is characterized by selectivity and saturability and requires energy expenditure by the cell. 主動(dòng)轉運 這種轉運過(guò)程的特征是選擇性和飽和性，需要細胞的能量消耗。
- The sodium/iodide symporter (NIS) is an intrinsic membrane protein that mediates the active transport of iodide into the thyroid and other tissues. 鈉/碘同向轉運體(NIS)是一種調節甲狀腺及其他組織碘轉運活性的膜蛋白。
- This pH4 recovery, which indicatied an active transport, failed to occur after removal of Na+ from the superfusion fluid. Ee-addition of Na+ resulted in a full pH4 recovery. 這個(gè)pHi恢復過(guò)程是一個(gè)H~+的主動(dòng)轉運,用膽堿離子取代培灌液中的Na~+可以抑制pHi的恢復,這種抑制作用是可逆的。
- Because concentrations of biotin in serum are in the low range of nMol/L,C. albicans probably satisfies its requirenment for biotin in vivo principally via active transport. 由于血清中的生物素含量在pMol/L到幾個(gè)nMol/L之間，白色念珠菌在體內可能通過(guò)主動(dòng)攝取生物素機制滿(mǎn)足其營(yíng)養代謝需求。
- ULTRASTRUCTURAL STUDIES ON SODIUM AND POTASSIUM ION ACTIVE TRANSPORTATIONS IN THE RAT EPIDIDYMIS. 大鼠附睪鈉鉀離子主動(dòng)轉運的超微結構研究
