What are the two distinct regions in a phospholipid?
a negatively charged and thus hydrophilic phosphate head two non polar hydrophobic fatty acides
The top is the hydrophilic head
The P is the phosphate group
the bottle is the hydrophobic tails

mingling together and shielded from water
What is a plasma membrane? and what does it do?
The boundary between the living cells and it's surroundings, controls the traffic
What are the main components of biological membranes?
What are the 2 distinct regions in a phospholipid bilayer?
a negatively charged and thus hydrophilic phophate group (head) and two non polar, hydrophobic fatty acid tails
What are attached to the phospholipid bilayers?
What kind of molecules can pass through the bilayer and which ones?
non polar molecules,
such as 0
What is a way a molecule passes through the bilayer?
The structure of membranes correlates with their functions
