Wake-up1. 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-up1. Explain the difference between energy in

terms of carbs and lipids.

2. What are the monomers of the following:a. Nucleic acidb. Carbohydratec. Proteind. Lipid

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 PolysaccharidesCellulose: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
