1. Day 5 AIM: What are Organic and Inorganic molecules?
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. 1) 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.

3. 2) Organic and inorganic molecules
Molecules can be grouped into two categories:
- Organic
- Inorganic

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

5. * 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

6. 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.

7. 6 Carbon dioxide molecules
Photosynthesis
6 Carbon dioxide molecules
6 water molecules
1 Glucose Molecule
6 Oxygen Molecules

8. 4) What are some important organic molecule?
4) There are four major groups of organic molecules that are important to all living things:
Carbohydrates- C1H2O1
Lipids- C2H1O1
Proteins-C H O N (Nitrogen)
Nucleic Acids- C H O N P (Phosphorous)

9. 5) What are some important inorganic molecule?
4) There are four major groups of inorganic molecules that are important to all living things:
Salt- NaCl
Water-H2O
Carbon dioxide-CO2
Oxygen-O2

10. Carbohydrates – plays an important role as a source of energy.
Include sugar and starch.
They are ring shaped.
The subunit (building blocks)
of carbohydrates
is simple sugars such as
glucose.

11. - Glucose
Starch -

12. Lipids (fats) – plays an important role in membrane production.
They are very large
molecules.
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.
Subunits of proteins are amino acids.
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
