the liver is involved in detoxification of many poisons and drugs. which of the following structures is primarily involved in this process and therefore abundant in liver cells?
smooth er
rough er
golgi apparatus
nuclear envelope
question 4
1 pts
which of the following statements correctly describes a function of the golgi apparatus?
production of ribosomal subunits
protein modification and sorting
detoxification of drugs
synthesis of cytoplasmic proteins

Explanation:

For Question 3: The smooth endoplasmic reticulum (smooth ER) is specialized in lipid synthesis and detoxification of poisons/drugs, so it is abundant in liver cells. Rough ER is for protein synthesis, Golgi apparatus processes and sorts proteins, and the nuclear envelope encloses the nucleus.
For Question 4: The Golgi apparatus receives proteins from the ER, modifies them (e.g., adding carbohydrates), and sorts them for transport to their final destinations. Ribosomal subunits are produced in the nucleolus, detoxification is done by smooth ER, and cytoplasmic proteins are synthesized by free ribosomes.

Answer:

Question 3: smooth ER
Question 4: protein modification and sorting
