Monomers are amino acids, what is the polymer?
What are proteins
List and describe 2 lipids in structure of cell membrane.
phospholipids - major structural component allow membrane to be semipermeable; cholesterol - helps maintain fluidity and stability of membrane
What are the components of a nucleotide
5 carbon sugar, Phosphate group, Nitrogenous Base
Anabolic reaction that joins monomers to form a larger polymer.
What is dehydration synthesis

What is amylose, amylopectin (starches - energy storage) and cellulose (structure)
Macromolecule that forms structural components in humans
What are proteins
List and describe 4 levels of protein structure

name and describe structure of the main plasma membrane lipid
What is a phospholipid; it contains a glycerol with 2 fatty acid tails (hydrophobic) and a phosphate group (hydrophillic)
Name 3 polysaccarides

What is Peptide bonds
List the 3 types of proteins by their function
What is structural, carrier, enzymes, antibody, muscle/contractile, hormones
Explain the process of denaturization.
Proteins exposed to high temperature or extreme chemicals permanently remove the secondary, tertiary and quaternary structure of proteins...and it no longer works properly
Function of Enzymes
speed up chemical reactions, act as a catalyst, lower the activation energy needed to jump start a reaction
Why conditions do enzymes need in order to be effective?
Specific temperature and pH range
What is the function of DNA and RNA
What is DNA holds genetic code to build proteins; RNA carries code out of nucleus to ribosome to synthesize proteins
