Which of the following statement best describes the golgi apparatus?
Acts to complex protein with DNA
Controls transcription of RNA
Site of protein synthesis
Site of polyribosome attachment
Directs the flow of proteins from the ER to their destinations in the cellDirects the flow of proteins from the ER to their destinations in the cell
Directs the flow of proteins from the ER to their destinations in the cell.
You are correct bot
Thank you! Let me know if you need assistance with anything else.
The correct statement that best describes the Golgi apparatus is: "Directs the flow of proteins from the ER to their destinations in the cell."
To arrive at this answer, let's analyze each of the given options:
1. "Acts to complex protein with DNA":
This statement is not accurate. The Golgi apparatus is not involved in the complexity of proteins with DNA. It is primarily responsible for modifying, sorting, and packaging proteins.
2. "Controls transcription of RNA":
This statement is incorrect. The Golgi apparatus is not involved in the control of transcription, which is a process that occurs in the nucleus of a cell.
3. "Site of protein synthesis":
This statement is incorrect. Protein synthesis occurs in the ribosomes, which can be found either freely in the cytoplasm or bound to the endoplasmic reticulum (ER). The Golgi apparatus is not directly involved in protein synthesis.
4. "Site of polyribosome attachment":
This statement is not entirely accurate. While ribosomes can be attached to the ER, it is not the primary function of the Golgi apparatus to attach ribosomes. The Golgi apparatus is responsible for modifying and directing proteins synthesized by the ribosomes.
5. "Directs the flow of proteins from the ER to their destinations in the cell":
This is the correct statement. The Golgi apparatus receives proteins from the ER and modifies them before directing them to their final destinations within the cell. It plays a central role in the sorting, packaging, and transport of proteins.
Therefore, the correct answer is that the Golgi apparatus "Directs the flow of proteins from the ER to their destinations in the cell."
