Question

Examination of a cell by transmission electron microscopy reveals a high density of ribosomes in the cytoplasm. This observation suggests that this cell is actively producing large amounts of which of the following molecules:________________
A) polysaccharides
B) proteins
C) lipids
D) nucleic acids

Answer 1

Answer:

B) proteins

Explanation:

The ribosomes are the organelles responsible to produce the rRNA, which together the mRNA and tRNA do the mechanism of translation: the genetic information of DNA is used to produce proteins. So a large amount of ribosomes indicates a large production of proteins.
