Question

(3 of 10) which of the following organelles is responsible for protein synthesis?
○ golgi apparatus
● ribosomes
○ mitochondria
○ microtubules
○ lyzosyme

Explanation:

To determine the organelle responsible for protein synthesis, we analyze each option:

• Golgi apparatus: Modifies, sorts, and packages proteins, not synthesizes them.
• Ribosomes: Are the sites of translation, where mRNA is used to assemble amino acids into proteins, so they are responsible for protein synthesis.
• Mitochondria: Are the powerhouses of the cell, producing ATP (energy), not involved in protein synthesis.
• Microtubules: Are part of the cytoskeleton, providing structural support and involved in cell movement/division, not protein synthesis.
• Lysozyme: Is an enzyme (not an organelle) that breaks down bacterial cell walls, not related to protein synthesis.

Answer:

B. ribosomes (Note: Assuming the options are labeled with letters, if the original had labels like A - E, and ribosomes is the correct one, the answer would be the option with ribosomes. From the given options, the correct one is ribosomes, so the answer is the option with "ribosomes" as the text, e.g., if it's option B, then B. ribosomes)
