DNA’s Job
Makes proteins that code for cells
RNA’s Job
Helps make the proteins coded by DNA by transferring the “recipe”
Ester Bond
When fatty acids are joined to a glycerol
Chemical Reactions
A process in which one or more substances are changed into others
Reactants
Substance being broken down or combined
Products
New substances formed in the reaction
Catalysts
Substances that speed up the rate of chemical reactions without being destroyed or changed
Enzymes
Proteins that catalyze (speed up) chemical reactions in cells
Substrate
Substance that is acted on in an enzyme
Nucleic Acid’s Enzyme
Deoxyribase
Substrates Are
The reactants in the enzyme’s chemical reaction
Active Site
The site on an enzyme where the substrate bonds to
Elements
Substances made of one type of atom
Compounds/Molecules
A group of atoms bonded together to take part in a chemical reaction
