a. Cells can produce proteins. pb pb pb
b. Cells can secrete digestive enzymes. pb pb pb pb
c. Cells can take in and use nutrients. pb pb pb pb pb pb
d. Cells can synthesize fats. pb pb pb

In metabolic absorption, all cells take in and use nutrients and other substances from their surr

2. Where is most of a cell’s genetic information, including RNA and DNA, contained?
pb pb pb pb pb pb pb pb pb pb pb pb
a. Mitochondria
b. Ribosome
c. Nucleolus
d. Lysosome
ANS: C p b
The nucleus contains the nucleolus, a small dense structure composed largely of RNA, most
pb pb pb pb pb pb pb pb pb pb pb pb pb pb
of the cellular DNA, and the DNA-
pb pb pb pb pb pb
binding proteins, such as the histones, which regulate its activity. The mitochondria are respo
