Enzymes that are integral part of ribosomes are involved in the synthesis of which of the following molecules?
Correct answer: B. B: Proteins
- A. A: Lipids
- B. B: Proteins
- C. C: Carbohydrates
- D. D: All of these
Explanation
Ribosomes are essential for protein synthesis in cells. They read the sequence of the mRNA and assemble amino acids into polypeptide chains, which fold into functional proteins. This process is specific to proteins, and ribosomes do not play a part in the synthesis of lipids or carbohydrates. Lipids are synthesized in the endoplasmic reticulum and cytosol, while carbohydrates are produced via different pathways like photosynthesis in plants. Therefore, the correct answer is proteins. Options A, C, and D are incorrect because they suggest synthesis activities not performed by ribosomes.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
