Question

proteins are important biomolecules. proteins are synthesized and often packaged for secretion into other cells within an organism. a variety of organelles play a role in producing, packaging, and moving proteins. can you match the organelle with its function?
nucleus
ribosome
endoplasmic reticulum
golgi apparatus
vesicle
:: this organelle sorts and packages proteins.
:: protein assembly is completed here and proteins are readied for transport.
::
initial sequence of nitrogen bases that determine type of protein comes from this organelle.
:: this small package carries the protein to the cell membrane.
:: the site of protein synthesis.

Explanation:

• Nucleus: It contains DNA which has the initial sequence of nitrogen bases (genes) that determine the type of protein (through transcription to mRNA).
• Ribosome: Ribosomes are the site of protein synthesis (translation of mRNA to protein).
• Endoplasmic reticulum: Protein assembly is completed here (e.g., in rough ER where ribosomes are attached) and proteins are readied for transport (e.g., by budding off vesicles).
• Golgi apparatus: This organelle sorts and packages proteins (modifying, concentrating, and packaging them into vesicles).
• Vesicle: Small packages (like transport vesicles) carry the protein to the cell membrane (for secretion or other destinations).

Answer:

• Nucleus: Initial sequence of nitrogen bases that determine type of protein comes from this organelle.
• Ribosome: The site of protein synthesis.
• Endoplasmic reticulum: Protein assembly is completed here and proteins are readied for transport.
• Golgi apparatus: This organelle sorts and packages proteins.
• Vesicle: This small package carries the protein to the cell membrane.
