- selectively permeable & structural support

Question 2

what is the role of the cytoskeleton

Answer 2

structural (strength) and functional (movement of things)

Question 3

what is the nucleus’ role

Answer 3

control center for cellular homeostasis (determines structure, function, quantity etc.)

Question 4

what is the role of ribosomes

Answer 4

responsible for protein synthesis and often associated with ER

Question 5

how are ribosomes associated with ER

Answer 5

if proteins need to exit cytosol, they are bound to ER

Question 6

what is the ER

Answer 6

-network of intracellular membranes continuous with the nucleus envelope
-smooth and rough ER

Question 7

what are the functions of smooth ER

Answer 7

synthesize lipids, hormons, glycogen

Question 8

what are functions of RER

Answer 8

-synthesized proteins are chemically modified and packaged to GA

Question 9

what is the role of the golgi apparatus

Answer 9

-packaging center
-modifies, packages, and renews
-e.g. hormones to exit cell via exocytosis

Question 10
