What are the names of the four main biomolecule groups?
carbohydrates, lipids, proteins, and nucleic acids
What do carbohydrates provide for the body?
They provide the body's primary source of energy
What food group is made up of lipids?
fats and oils
Enzymes are proteins. Where can enzymes be found?
in ALL living things (people, plants, animals)
Nucleic acids carry genetic coding information. What are the names of the two groups of genetic code?
DNA and RNA
What is a monomer?
a single molecule that can be bonded to other identical molecules to form a polymer (many molecules)
Describe how simple carbohydrates work.
They break down quickly into glucose to be used as energy.
How do lipids support the cells?
They give the cells structure.
What are proteins made of? And how many are there?
amino acids
there are 20
A monomer (or molecule) of nucleic acid is a nucleotide. What is the purpose of a nucleotide?
the basic building block of nucleic acids (DNA and RNA).
What components bond with adenine?

Saccharides are sugar.
What is the difference between monosaccharides and disaccharides?
Monosaccharides have only one sugar (simplest form of carbohydrates).
Disaccharides have two sugars.
Name TWO of the four key functions of lipids.
* control what goes in and out of your cells
* store energy
* absorb vitamins
* make hormones
Enzymes are a type of protein. What do enzymes do?
speed up metabolism
What is the purpose of a DNA double helix?
to allow genetic information to be copied and passed on to the next generation
What happens during a catalyzed chemical reaction?
a substrate attaches to an enzyme and produces products such as glucose and fructose (sugars) 
Name four types of carbohydrates by scientific name and function.
* cellulose- structure of plant cell walls
* chitin- structure of fungal cell walls
* glycogen- energy in the form of glucose
* starch- energy stored in plant roots and seeds
What is a shared function of carbohydrates and lipids?
store energy
What happens in a condensation reaction?
2 or more molecules combine to make a larger molecule AND a small molecule of water is lost.
What is the difference between DNA and RNA?
RNA is a single strand of code; DNA is a double strand of code.

For an enzyme to be able to catalyze (accelerate) a reaction, the active site must have what?
a complementary shape to the substrate (or base on which an organism lives)
