Question

A pathologist working in the lab observed a liver cell that had a very prominent endoplasmic reticulum. The cell also had a proportionately larger smooth endoplasmic reticulum than rough endoplasmic reticulum.

Which of the following is a plausible explanation for the purpose of a larger amount of smooth endoplasmic reticulum?

A) It is producing proteins for glycolysis and ATP generation.
B) It is packaging signal hormones for export out of the cell.
C) It is detoxifying drugs and toxins with hydroxylating enzymes.
D) It is folding membrane-bound proteins bound for the plasma membrane.

Answer 1

B - packaging signal hormones for export out of the cell

Step-by-step explanation:

Remember the smooth ER packages proteins and sends them out of the cell through vesicles (endo/exosymbiosos)

Answer 2

C. It is detoxifying drugs and toxins with hydroxylating enzymes.
