1. DO NOW
On the top of you note packet, write down 3 things that you might see on the nutrition label on the back of a can of food.

2. AIM: The Chemistry of Life- Organic and Inorganic

3. Why is Chemistry important in Biology? (review)
1) All living things are made up of atoms and molecules.
Living things are constantly under going chemical reactions.
All of which is what chemistry is all about.

4. Organic and inorganic molecules
Molecules can be grouped into two categories:
- Organic
- Inorganic

5. Organic molecules are molecules that contain at least 1 Carbon and at least 1 Hydrogen.

6. * Inorganic Molecules are all the other molecules that do not fit the definition of organic molecules.
* Remember that inorganic molecules can have carbon and hydrogen but they cannot be in the same molecule. C O

7. 3) Are organic molecules more important than inorganic molecules?
3) Inorganic molecules are important because they can be broken apart and recombined to make organic molecules.
Also inorganic molecules (such as water) are important for certain body processes.

8. 6 Carbon dioxide molecules
Photosynthesis
6 Carbon dioxide molecules
6 water molecules
1 Glucose Molecule
6 Oxygen Molecules

9. What are some important organic molecule?
There are four major groups of organic molecules that are important to all living things:
Carbohydrates
Lipids
Proteins
Nucleic Acids

10. Carbohydrates – plays an important role as a source of energy.
They are sugar and starch.
They are ring shaped.
Glucose (sugar) is a small
molecule.
Starches are large molecules.
The subunit (building blocks)
of carbohydrates
is glucose.

11. - Glucose
Starch -

12. Lipids (fats) – plays an important role in membrane production.
They are very large
molecules.
They are found in oils,
fats, and wax.
Their subunits are
fatty acids.

13. Protein – the building blocks of all living things.
They are very large molecules.
Their shape determines their function (job).
Subunits of proteins are amino acids.
Some types of proteins are:
* Enzymes
* Hormones
They are found in meats
and eggs.

14. Nucleic Acid – plays a major role in genetics
DNA
RNA
The subunit of nucleic acid are nucleic bases.

15. Let’s Review
What is the difference between an organic and inorganic molecule?
What is the difference between an atom and a molecule?
What are the 4 types of organic molecules?
Organic molecules have both a
carbon and a hydrogen
Molecules are made from
2 or more atoms
Carbohydrates, Lipids, Proteins and Nucleic Acids

16. Let’s Review What is the subunit of carbohydrates?
What is the subunit of lipids?
What is the subunit of proteins?
What is the subunit of nucleic acids?
Glucose
Fatty Acids
Amino Acids
Nucleic Bases

17. Let’s Review Which organic molecule is ringed shaped?
Which organic molecule is used in genetics?
Which organic molecule is found in wax?
Enzymes are what type of organic molecule?
Carbohydrates
Nucleic Acids
Lipids
Proteins
