Cell
Basic structural and functional unit of life- diverse (200 types. prokaryotic & eukaryotic)- made of organelles
Organelle
Any number of organized or specialized structures within a living cell.
Macromolecule
Larger molecules linked through covalent bonds, which contain information on how to run the body, and providing the energy needed to do so.
Nucleotide

Fatty Acid
The building blocks of the fat in our bodies and in the food we eat. During digestion, the body breaks down fats into fatty acids which can join together in groups of three, forming a molecule called a triglyceride.
Monosccharide
The simplest forms of sugar and the most basic units from which all carbohydrates are built.
Amino Acid
Building blocks of protein
Enzyme
Proteins that are biological catalysts.
Catalyst
Speeda up biochemical reactions by lowering the activation energy needed to get reaction going.
Active Site
Highly specific spot where enzymes bind to certain substrates (reactants).
Differentiation
The process of stem or undifferentiated cells going through specialization to become specific cells with different functions.
