Term
Carbon, hydrogen, oxygen, nitrogen
Definition

96.3% of your body is make up of these 4 elements.

 

Term
Monomer
Definition
In the process called polymerization macromolecules are formed from smaller particles.  One molecule that contains a carbon is called. 
Term
Polymer
Definition
A couple of monomers together are called
Term
macromolecules
Definition
Several polymers put together are called:
Term
Carbon
Definition
This element has 4 valence electrons which form 4 covalent bonds.  It is one of the elements that are found in macromolecules.
Term
Carbohydrates
Definition
Its chemical make-up is carbon, hydrogen, and oxygen in a 1:2:1 ratio.
Term
Carbohydrates
Definition

Its functions include:

Main source of energy and is used in structural material.

Term
Carbohydrates
Definition
Examples of this macromolecule are sugars and starches.
Term
Carbohydrates
Definition
This macromolecules is stored in your muscles and liver.
Term
Monosaccharides
Definition
Carbohydrates made up of monomers.
Term
polysaccharides
Definition
A complex sugar made of 3 or more monosaccharides.
Term
disacchaarides
Definition
Two monosaccharides join to form a double sugar.
Term
dehydration synthesis
Definition
When two monosaccharides combine a water molecule is formed.  This process is called:
Term
Lipids
Definition
Its chemical make-up is carbon, hydrogen and oxygen
Term
Lipids
Definition

This macromolecules functions include:

Stores energy,

Forms membranes and waterproof membranes

Used in structural materials

Insulation
Chemical messengers

Term
Lipids
Definition
Examples of this macromolecules include:
saturated and unsaturated fats
Term
Lipids
Definition
This macromolecule is stored under your skin and in your liver.
Term
proteins
Definition
Its chemical make-up includes carbon, hydrogen, oxygen and nitrogen.
Term
protein
Definition

This macromolecule aids in:

Cell growth and repair,

Controls reaction rates

Transports substances in and out of the cell.

Term
protein
Definition
This macromolecule is made in the ribosomes
Term
protein
Definition
Examples of this macromolecules are:
enzymes and amino acids
Term
Nucleic Acids
Definition
its chemical make-up are carbon, hydrogen, oxygen, nitrogen and phosphorus.
Term
Nucleic Acids
Definition
The function of this macromolecule is to transport genetic material.
Term
Nucleic Acids
Definition
Examples of this macromolecule is DNA and RNA.
Term
Nucleic Acid
Definition
This macromolecule is found in the nucleus.
Term
Lipids
Definition
This macromolecules cause a waxy build-up of cholesterol in your blood vessesl.
Term
Diabetes
Definition
It is a disease that affects how the body uses glucose.
Term
Activation energy
Definition
The energy needed to kick-start a chemical reaction.
Term
Enzymes
Definition
They are molecules that serve as a catalyst.  They speed up the reaction, lower the amount of activation energy needed and regulate chemical pathways.
Term
Substrate
Definition
Enzymes provide a site where reactants of a chemical reaction can occur and lowers the amount of activation energy. What are these reactants called?
Term
                                               Active site
Definition
The site where reactants are brought together, so that the chemical reaction happens quicker with less activation energy.
