Question

what is the main job of ribosomes in eukaryotic cells? think about how proteins are made in the cell. (2 points) they make fats (lipids) and hormones for the cell they add sugars or fats to proteins and prepare them to leave the cell they read the mrna code and build proteins they produce energy for the cell through cellular respiration

Explanation:

Ribosomes are cellular structures. In protein synthesis, mRNA (messenger RNA) carries the genetic code. Ribosomes bind to mRNA. They read the codons (triplet nucleotide sequences) on mRNA. Then, using transfer RNA (tRNA) that brings amino acids, they assemble amino acids into polypeptide chains (proteins).

• The first option (making fats/lipids and hormones) is not the role of ribosomes. Lipids are mainly synthesized in the endoplasmic reticulum.
• The second option (adding sugars/fats to proteins) is a function of the Golgi apparatus (glycosylation, etc.).
• The fourth option (producing energy via cellular respiration) is the job of mitochondria.

Answer:

They read the mRNA code and build proteins.
