Basic Structures of Life
Describe the makeup of an atom.
nucleus contains protons & neutrons
energy levels contain electrons
Provides structure to the cell, insulates nerves, makes hormones and cushions organs.
Lipids
Ions that have a negative charge.
Anions
Which type of compounds contains carbon?

Builds larger, more complex molecules from smaller ones and requires energy.
Anabolism
Covalent Bond
when two atoms share electrons to fill the outer shell
Help form the structure of cell membranes.
