Module1: Principles of Cell Function Flashcards
1
Q
Most abundant molecules
A
Phospholipids
2
Q
Phospholipids are amphipathic molecules
A
Amphipathic molecules containing both compounds that polar (like being in water) and non-polar (does not like being in water)
3
Q
What is an example of the fluid “mosaic” model mean in molecules?
A
the membrane is fluid with a
mosaic of proteins embedded in it
4
Q
Amphipathic phospholipids are made up of
A
Hydrophilic head, Hydrophobic head
5
Q
Hydrophobic tails in amphipathic phospholipids are
A
The lipid part of the molecule -> consists of C and H; hence, not likely to interact with water on either the outside or inside of the cell.
6
Q
Hydrophilic heads in amphipathic phospholipids are
A
interacting with water molecules.
