标题[问题][生物] function of the nucleolus & cellular secretion
时间Mon Nov 22 00:04:35 2010
大家好,我又来给大家动脑筋了
问题一:
A2 Ch.3 No.13
What is the function of the nucleolus?
(A)to contain the hereditary blueprint of the cell
(B)to modify substances made on the endoplasmic reticulum
(C)to organize the spindle fibers for cell division
(D)to manufacture ribosomes
(E)none of the above
正解是(D),为何(A)不行呢?细胞核内不是包含 DNA,DNA 不是被称为遗传的蓝图吗?
问题二:
A2 Ch.3 No.20
Which one of the following organelles would be especially abundant
in the pancreatic cells that produce digestive enzymes?
(A)rough endoplasmic reticulum
(B)smooth endoplasmic reticulum
(C)lysosomes
(D)microfilaments
(E)mitochondria
正解是(A),可是之前听沈浩好像说过
分泌旺盛的细胞 mt 会发达,然後才是选 RER 跟 Golgi
还是我记错了呢?
另外,遇到此类的问题实际上是 mt, RER 跟 Golgi 都会很发达对吧?
那要怎麽选答案呢?
感谢
====================题外话一下=====================
以後发问问题的文章是不是在标题有个问题的关键字
这样以後的人搜寻起来会不会比较方便一点?

1F:推 undeadfish:nucleolus是核仁不是细胞核 11/22 00:29
2F:推 luckylogo:胰脏cell会分泌酵素,属分泌性蛋白,没记错的话RER有这 12/01 00:15
3F:→ luckylogo:个功能,粒线体当然也不能说错,只是RER会比MT好,再来 12/01 00:16
4F:→ luckylogo:好险你第一题没去问老师,不然应该会被他电爆,他好care 12/01 00:17
5F:→ luckylogo:因为这个英文单字被他电爆的人真的还蛮多的 12/01 00:18
