Lecture 3 (8/29/16) Study Questions
1. List the 3 different types of fibers that
make up the cytoskeleton. Aren’t they cool?!

smooth ER and rough ER?
3. List the functions of: smooth ER, rough
ER, lysosomes, vesicles, vacuoles.
4. Which organelle is in charge of cellular
respiration?
5. Define cellular respiration.
