1. Biology: What are the parts?
Science all related, biochem…

2. Biological Components
Atom: the basic unit of matter
Element: pure substance that consists entirely of one type of atom (periodic table of elements)
SHOW GRAPHIC THINGYYYYY

3. Biological Components
Molecule: two or more atoms joined together (examples: water molecule, H2)
Compound: formed by two or more elements in a set proportion (H2O, NOT H2, NaCl)

4. Biological Components
Macromolecule: large molecules composed of thousands, hundreds of thousands of molecules, formed through polymerization of monomers to polymers.
Cell: basic unit form of life, smallest unit an organism can be to be considered alive

6. Word Roots
Mono: one
Poly: many
-mer: part
Macro: large

7. Source of Energy
We get our energy from the outside environment. Thus, we get our energy from our food.

8. Living things!
All living things are made up from carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur.

9. Hierarchy of Life

10. Macromolecules Example: links in a chain Monomer: Polymer:
Polymerization:

11. Macromolecules Example: links in a chain Monomer: individual link
Polymer: links together
Macromolecule: the chain
Polymerization: the process of making the chain

12. Macromolecules Macromolecules are composed of single molecules.
Macromolecules form from monomers linking together in a process called polymerization.
The product of several monomers is called a polymer.

13. Macromolecules Think and share:
What is another analogy for monomers making up macromolecules?

14. 4 Macromolecule Types 1. Carbohydrates 2. Lipids 3. Proteins
4. Nucleic Acids

15. 1. Carbohydrates
Living things use carbohydrates as their main source of energy. Carbohydrates are sugars.

16. 2. Lipids
Lipids are used to store energy, and are important parts of biological membranes and waterproof coverings.

17. 3. Proteins Proteins can…
control the rate of reactions and regulate cell processes.
form bones and muscles.
transport substances into or out of cells to help fight disease.

18. 4. Nucleic Acids
store and transmit genetic information (DNA/RNA)

19. Class of Organic Compounds
Carbohydrate
 Nucleic Acid
Protein
Monomer
Nucleotide
Polymer
Fats, Waxes, Oils, Steroids
