Lecture 3: The Plasma Membrane
They are Semipermeable
Diffusion
Known as the phospholipid bilayer
Phospho= Phosphate group
Lipid = Fatty Acid
Bilayer= TWO layers
It forms because of interactions of
Water
:!!:
Chemical formula is H2O
Water is formed when hydrogen and oxygen share
ELECTRONS :!!:
Electrons have a negative charge (-)
They orbit around the nucleus
Made of protons and neutrons
Protons = Positive (+)
Neutrons = No charge
When atoms share
ELECTRONS
, a chemical bond forms
If the electrons orbit around both nuclei
EQUALLY
A
NON-POLAR COVALENT BOND
is formed
STRONGEST
kind of bonds
Hard to break
really good to store energy
COVALENT
= sharing electrons
If the electrons orbit around both nuclei
UNEQUALLY
A
POLAR COVALENT BOND
is formed
