Which of the following is most likely synthesized on free ribosomes?

Question

Quizplus · Accepted Answer

Polypeptide chains that form enzymes which function in glycolysis do not require membrane-bound organelles for their synthesis, and are therefore most likely synthesized on free ribosomes. Glycolysis occurs in the cytoplasm, which is where free ribosomes are located. Electron carriers of the electron transport chain are synthesized on membrane-bound ribosomes in the mitochondria. Polypeptide chains that form immunoglobulin molecules are synthesized on membrane-bound ribosomes and undergo post-translational modifications in the endoplasmic reticulum and Golgi apparatus. Lysosomal enzymes are also synthesized on membrane-bound ribosomes and undergo post-translational modifications in the endoplasmic reticulum and Golgi apparatus before being targeted to lysosomes.
