Question 8

Smooth Endoplasmic Reticulum

Answer 8

lipid and cholesterol synthesis and metabolism and drug toxin detoxification

Question 9

Rough Endoplasmic Reticulum

Answer 9

modify proteins made by ribosomes

Question 10

Golgi Apparatus (Complex)

Answer 10

modifies and packages proteins for export or use in the cell

Question 11

Lysosome
