Q

What is the relationship of the head of the phospholipid to water?

A

Hydrophilic

17
Q

What is the relationship of the tail of the phospholipid tails?

A

Hydrophobic

18
Q

Due to the hydrophobic properties of the fatty acid tails, what is created to form a cell membrane?

A

Phospholipid bilayer

19
Q

What are the two types of proteins in the cell membrane?

A

Integral and Peripheral

20
Q

What are the characteristics of integral proteins?

A

Embedded and anchored to the CM by hydrophobic interactions

21
Q

What are the characteristics of peripheral proteins?

A

Not embedded in CM or bonded but attached by electrostatic interactions

22
Q

Name two examples of peripheral proteins.

A

Ankyrin, Cl-/HCO3- exchanger

23
Q

What is created when there is a cis double bond in a phospholipid?

A

kink, allows for better saturation and flow
