Answer 18

Free ribosomes

Question 19

These are found attached to the ER and will make proteins that will eventually be shipped.

Answer 19

Bound ribosomes

Question 20

This is a system of tubes filled with enzymes that will synthesize hormones, detox materials, and break down lipids.

Answer 20

Smooth ER

Question 21

This is a system of sacs covered in ribosomes that will modify proteins
