Organic vs. Inorganic Molecules If you understand these building blocks, future units will be a breeze!

Types of Molecules • Molecules are elements that are bonded together. There are two

Types of Molecules • Molecules are elements that are bonded together. There are two types of molecules. – Organic – living or once living – Inorganic – nonliving

Types of Molecules • Remember the elements carbon and hydrogen? Well, when these elements

Types of Molecules • Remember the elements carbon and hydrogen? Well, when these elements are found together, they make an ORGANIC molecule. • Organic = C + H together • Inorganic = no C + H together SO, everything that is living is ORGANIC, it contains C and H.

Organic or Inorganic? HCl H 2 O C 6 H 12 O 6 CO

Organic or Inorganic? HCl H 2 O C 6 H 12 O 6 CO 2 C 3 H 7 NO 3

Inorganic Molecules • There are millions of inorganic molecules, but there are only a

Inorganic Molecules • There are millions of inorganic molecules, but there are only a few you MUST know • H 2 O = water • CO 2 = carbon dioxide • O 2 = oxygen • NH 3 = ammonia

Organic Molecules • There are 4 types of organic molecules. • Meaning, EVERYTHING that

Organic Molecules • There are 4 types of organic molecules. • Meaning, EVERYTHING that is living is made up of a mixture of these 4 substances. – Proteins – Carbohydrates (Sugars) – Lipids (Fats) – Nucleic Acids (DNA) You are what you eat! We do not eat inorganic materials, we eat organic. Protein, carbs, and fats are our nutrition!

Organic Molecules • Organisms either consume or produce their nutrition. However these molecules need

Organic Molecules • Organisms either consume or produce their nutrition. However these molecules need to be broken down so they can be used for various needs. Complex Molecules: Simple Units: Proteins Carbs Lipids LEGO DEMO

Proteins • The building blocks of proteins are amino acids. • Proteins are important

Proteins • The building blocks of proteins are amino acids. • Proteins are important for many reasons. – Enzymes – chemical reactions – Body growth and repair What kinds of protein do we eat?

Carbohydrates • The building blocks of carbohydrates are simple sugars. • C 6 H

Carbohydrates • The building blocks of carbohydrates are simple sugars. • C 6 H 12 O 6 is sugar. Because of sugars structure, it is represented as in science. • Carbohydrates provide: – Energy What kinds of carbs do we eat?

Lipids • The building blocks of lipids are fatty acids. • Lipids are important

Lipids • The building blocks of lipids are fatty acids. • Lipids are important because they: – Provide stored energy – Make up the cell membrane What kinds of fat do we eat?

Nucleic Acids • Nucleic Acids make up the organisms heredity. It is the DNA,

Nucleic Acids • Nucleic Acids make up the organisms heredity. It is the DNA, or the genetic code for all living things. • Yes, every living organism from a sponge to a whale has DNA.
