Nutrient Cycling

• All Life is composed of four basic molecules.

2
Nucleic Acids

• Examples RNA DNA
• Monomers Nucleotides
• Jobs
• Store Genetic Information
• Instructions to make proteins

DNA
3
Proteins

• Examples Enzymes Rhodopsin insulin
• Monomers Amino Acids
• Jobs
• Control chemical reactions
• Building blocks of cells

4
Carbohydrates

• Examples Sucrose, Fructose, Glucose
• Monomers monosaccharide
• Jobs
• Energy source for cells
• Stored energy.

5
Fats
Glycerol

• Examples Bilayer
• Monomers 3 fatty acids and a Glycerol
• Jobs
• Build membranes
• Stored energy

Fatty Acids
6
Enzymes

• Enzymes are globular proteins. Also called
  biological catalysts (Catalysts speed up chemical
  reactions)
• Example galactase, Lactase
• Job Speed up chemical reactions

7
Macromolecule Summary on overhead

• Structural formula the actual structure of the
  molecule with all of the elements
• Molecular formula counting the elements that
  make up the structure of that molecule
• C6H12O6

8
Bonding and breaking

• Add a water or take a water away will bond or
  break apart two molecules

9

• Hydrolysis Reactions
• Addition of a water to break up two molecules

10
Dehydration Synthesis ReactionsRemoval of a
water to bond two molecules together
11

• Peptide bond bond made between two amino acids
  (removal of a water H2O)
