New cards
What is a phospholipid?
"A phospholipid is a lipid made of one glycerol
3
New cards
How is a phospholipid different from a fat?
"A fat has three fatty acids attached to glycerol
4
New cards
Which part of a phospholipid is hydrophilic?
The phosphate-containing head is hydrophilic.
5
New cards
Which part of a phospholipid is hydrophobic?
The fatty acid tails are hydrophobic.
6
New cards
Why is a phospholipid called amphipathic?
Because it has both a hydrophilic region and a hydrophobic region.
7
New cards
What structures can phospholipids form in water?
"They can form monolayers
8
New cards
What is a phospholipid bilayer?
It is a double layer of phospholipids in which the hydrophilic heads face water and the hydrophobic tails face inward.
9
New cards
What is the basic structure of cell membranes?
The basic structure of cell membranes is a phospholipid bilayer.
10
New cards
Why do membranes act as barriers to many water-soluble substances?
Because the inside of the phospholipid bilayer is hydrophobic.
11
New cards
What is one main function of phospholipids in cells?
They form the main structural framework of membranes.
12
New cards
How do unsaturated phospholipid tails affect membrane fluidity?
"They increase membrane fluidity because double bonds create kinks
13
New cards
What model describes membranes as a fluid phospholipid bilayer with proteins?
The fluid mosaic model.
14
New cards
What does the hydrophilic head of a phospholipid contain?
It contains the phosphate group.
15
New cards
What do the fatty acid tails of a phospholipid do in water?
They turn away from water and are shielded inside the bilayer or micelle.
16
New cards
Why do phospholipids form bilayers spontaneously in water?
Because their hydrophilic heads interact with water while their hydrophobic tails avoid water.
17
New cards
What is one signaling-related role of some phospholipids?
Some phospholipids can be modified to act as signaling molecules.
18
New cards
What happens to the phospholipid heads in a bilayer?
They face the aqueous environments on both sides of the membrane.
19
New cards
What happens to the phospholipid tails in a bilayer?
"They point inward toward each other
20
New cards
Why are phospholipids important for organelles?
They form the membranes around organelles.
21
New cards
What kind of substances have difficulty crossing the phospholipid bilayer directly?
"Ions
