Presentation transcript:

Wake-up 1.Compare and contrast the structure of a carbohydrate and a lipid. 2. Different organisms store glucose in different forms. You discover an unidentified specimen. Upon chemical analysis you find that it is made up of significant amounts of GLYCOGEN. Is it a dog, mushroom, grass, or a potato.

Wake-up 1.Explain the difference between energy in terms of carbs and lipids. 2.What are the monomers of the following: a.Nucleic acid b.Carbohydrate c.Protein d.Lipid

Levels of Organization in Life

Four Macromolecules: 1. Carbohydrates

Four Macromolecules: 2. Lipids

Four Macromolecules: 3. Proteins

Four Macromolecules: 4. Nucleic Acids

Carbohydrate Functions #1 Immediate energy source Burn quickly

Carbohydrate Function #2 Stored Energy Organisms store what they don’t use

Carbohydrate Function #3 Provide structure for plants, fungus, and arthropods

Example of a Polysaccharides Cellulose: Provides structure for plants

Example of a Polysaccharide Starch: Stored Energy in plants

Example of a Polysaccharide Glycogen: Stored energy in animals

Examples of a Polysaccharide Chitin: Structure and support for arthropods and mushrooms

Lipids Function #1 Long term energy storage

Lipids Function #2 Provide Insulation

Lipids Function #3 Regulate water movement in and out of the cell (cell membrane)

Steroid: Cholesterol Provide structure in the cell membrane. Used to make hormones such as estrogen. Lipids Function #4

Proteins Function #1 Make up the structure and function of muscles

Proteins Function #2 Provides structure in hair, nails, and skin

Proteins Function #2-cont. Provides structure feathers and hooves

Proteins Function #3 Blood has hemoglobin (protein) which helps transport oxygen

Proteins Function #4 Insulin (protein) helps glucose move from our bloodstream to our cells

Protein Function - #5 Enzymes (Protein) fuel every chemical reaction in organisms. Helps form bonds and break things down

Proteins Function #6 Help transport substances in and out of the cell

Nucleic Acid Function #1 Responsible for an organisms genetic make-up (DNA)

Nucleic Acid Function #2 Usable form of energy (ATP)

Nucleic Acid – Function #3 Makes Proteins: RNA
