Cards

Term
organic molecules
Definition
contains carbon and forms 4 bonds
Term
Functions of carbs
Definition
mono-immediate energy poly-stored energy cellulose and chitin- structure
Term
polysacchride
Definition
contains more than one ring
ex. starch,cellulose,glycogen,chitin
Term
disacchride
Definition
contains 2 rings
ex. maltose=glucose+glucose
lactose=glucose+galactose
sucrose=glucose+fructose
Term
monosacchride
Definition
contains one ring
ex. glucose, fructose, and galactose
Term
hydrolysis
Definition
the breaking of a bond
Term
dehydration synthesis
Definition
the building of a bond
Term
monomer
Definition
one unit of a polymer
Term
polymer
Definition
large molecule that is made up of monomers
Term
proteins elements
Definition
carbon, hydrogen,oxyen, nitrogen and sometimes sulfur
Term
monomer of proteins
Definition
amino acid
Term
protein functions
Definition
1.support
2.hormones
3.transport
4.defense/immunity
5.movement
6.enzyme
Term
a proteins shape is
Definition
very important in a function
Term
a proteins shape is determined by
Definition
the order of amino acids
Term
enzymes
Definition
biological catalyst- helps speed up the chemical reactions by lowering the activation energy
Term
characteristics of enzymes
Definition
1.specific
2.reusable
3.sensitive
Term
the enzymes active site must fit the
Definition
substrate in order for the reaction to work
Term
enzymes can be reused over and over again without
Definition
being changed or used up
Term
polypeptide
Definition
a chain of amino acids connected by the peptide bond.
Term
elements of a lipid
Definition
carbon hydrogen and oxygen
Term
what does every lipid have ?
Definition
an r group, a carboxyle group, and an amino group
Term
saturated fats
Definition
-single bonded
-straight
-solid
-bad for you
-harder to breakdown
ex of foods: donuts
Term
unsaturated fats
Definition
-liquid
-double bonded
-easier to breakdown
-ex of foods: avocado, nuts
Term
types of lipids
Definition
1. triglyceride-3 fatty acids, stores energy, cushions organs and insulates
2. steroid's- made of 4 fused rings, structure of some hormones; cholesterol-apart of cell membrane
3. phospholipid- 2 fatty acids, found in cell membrane
Term
elements of a nucleic acid
Definition
carbon, hydrogen, oxygen, nitrogen, and phosphate
Term
monomer of a nucleic acid
Definition
nucleotide
Term
what does every nucleic acid have?
Definition
nitrogen base, phosphate group,and a sugar
Term
what makes each nucleic acid different from the other?
Definition
the nitrogen base
Term
DNA
Definition
double stranded and stores genetic information
Term
RNA
Definition
single stranded and controls the making of proteins
Term
ATP
Definition
has a structure like a nucleotide, but is used for energy
