Verified step by step guidance
1
Identify the role of each organelle listed in the problem: Ribosome, Mitochondrion, Golgi apparatus, and Nucleus.
Recall that ribosomes are responsible for protein synthesis, translating mRNA into polypeptide chains.
Understand that mitochondria are the powerhouses of the cell, generating ATP through cellular respiration, not involved in protein modification or sorting.
Recognize that the nucleus contains genetic material and controls gene expression but does not process or package proteins.
Focus on the Golgi apparatus, which is known for modifying proteins received from the endoplasmic reticulum, sorting them, and packaging them into vesicles for secretion or delivery to other organelles.
