=Life Molecules =

Macromolecules- known as Giant Molecules, they are made from thousands or even hundreds of thouseands of smaller molecules.

Monomers- The smaller units which make up polymers

Polymers- Large links of Monomers that look much like a links on a metal watch band; or a multi-colored necklace.

Carbohydrates- Compounds made up of carbon, hydrogen, and oxygen atoms; usually in the ratio 1:2:1.

Monosaccharides- Single Sugar molecules

Polysaccharides- the large combination of monosaccharides.

Lipids- made mostly of carbon and hydrogen atoms. Common categories are fats, oils, and waxes.

Proteins- Building blocks of muscles and contain nitrogen along with macromolecules.

Amino acids- Proteins are polymers that are made up of monomers known as amino acids.

 Chemical Reactions


 * Chemical Reaction**- is a process that changes, or transforms, one set of chemicals into another.

-**Reactants**- The element or compound that enter into a chemical reaction -**Products**- The elements or compounds produced b a chemical reaction.


 * Activation Energy-** The energy that is needed to get a reaction started.

Enzymes


 * Catalyst**- A substance that speeds up the rate of a chemical reaction. Catalysts work by lowering a reaction's activation energy.


 * Enzymes-** Proteins that act as biological catalysts.


 * Substrates-** The reactions of enzyme-catalyzed reactions. The thing that had been given a catalyst...
