Which of the following best describes the function of the ribosomes in eukaryotic cells?
(1 point)
decodes the sequence of bases on the mRNA and then creates specific proteins
makes lipids and steroids that will be used in the production of membranes and hormones
modifies proteins that require specific
• attachments of sugars or lipids and packages proteins for export
energy-producing structure
• of the cell and location of cellular respiratige
decodes the sequence of bases on the mRNA and then creates specific proteins
The correct answer is: modifies proteins that require specific attachments of sugars or lipids and packages proteins for export.
The correct answer is option 1: "decodes the sequence of bases on the mRNA and then creates specific proteins." Ribosomes are cellular structures responsible for protein synthesis. They work by decoding the genetic information stored in messenger RNA (mRNA) and using it to assemble the appropriate sequence of amino acids, which form proteins.
To arrive at this answer, you could eliminate the other options:
- Option 2, "makes lipids and steroids that will be used in the production of membranes and hormones," does not describe the primary function of ribosomes. Lipid and steroid synthesis is mainly carried out by other cellular structures, such as the smooth endoplasmic reticulum.
- Option 3, "modifies proteins that require specific attachments of sugars or lipids and packages proteins for export," is more relevant to the Golgi apparatus and the endoplasmic reticulum, which are responsible for protein modification and packaging.
- Option 4, "energy-producing structure of the cell and location of cellular respiration," refers to the mitochondria, not ribosomes. Mitochondria are the powerhouses of the cell and are responsible for producing energy through cellular respiration.
By process of elimination, you can determine that option 1 is the best answer.
