Question 2,3,4
Cell and Molecular Biology 275 Fall 2018 Worksheet for Chapter 7 and 8.1-8.3-Due at start of Week 8 recitation meeting Students may work in groups, but must turn in individual papers for a grade. Question 1 (5 pts): List the five main functions of cell membranes: Question 2 (5 pts): Over 60% of a cells total membrane surface area (including those of its organelles) is the Endoplasmic Reticulum. Why do you think this is? Question 3 (5 pts): Many important small signaling molecules arrive at the outer cell surface and their signal is transduced through the cell membrane. What does this mean? Question 4 (5 pts): What is it about the polypeptide sequence of transmembrane proteins that make them stuck in the phospholipid bilayer instead of floating away (or sinking into the cells cystosol?) Question 5 (5 pts): We tend to think of hydrophobic molecules as being water fearing From what weve discusses about hydrophilic versus phobic, how might you elaborate orn this to make more sense?

Why do you think this is? Question 3 (5 pts): Many important small signaling molecules arrive at the outer cell surface and their signal is transduced through the cell membrane. What does this mean? Question 4 (5 pts): What is it about the polypeptide sequence of transmembrane proteins that make them "stuck" in the phospholipid bilayer instead of floating away (or sinking into the cell's cystosol?) Question 5 (5 pts): We tend to think of hydrophobic molecules as being "water fearing" From what we've discusses about hydrophilic versus phobic, how might you elaborate orn this to make more sense?
