Warm-up 1/31/12

•Teach the Teacher: What is the best kind of candy to get at the gas station?

• •Review: What are the three parts of an

experiment. •  •Learning Target: Defend Whether

something is alive or not. • Identify the 4 types of macromolecules.

Flash Card

•On the Front Write:

•Characteristics of Life

•On the Back write: •Made of cell (s)•Organization•Grows •Reproduces•Responds to

stimuli•Requires energy•Homeostasis •Has adaptations

Building Blocks of Cells

Science Biology Life Cells

Macromolecules •Macro=large •Molecules=two or more atoms bonded

together, like H20•Tons of repeating molecules bonded

together to make…macromolecules •Think of them like the wood for building

the framing of a house

4 types of Macromolecules

•Carbohydrates•Lipids •Proteins •Nucleic acids

Just like there are different materials used to make a house…different materials to make a cell.

Carbohydrates

•Store energy▫Sucrose, lactose,

glucose •Provide structural support▫Cellulose makes

cell wall of plants ▫Chitin is hard

outer layer in the hard outer shell of shrimp, lobsters, and some insects

In foods=sugar and starches

Lipids •Made up of carbon

and hydrogen •Make up fats, oils,

waxes▫Coated on leaves

(wax) ▫Beeswax for

honeycomb•Store Energy •Provide Barriers

for cells▫Phospholipids

•Include steroids and cholesterol

Lipids •Good lipids (fats)

▫UnSaturated fats•Not so good lipids (fats)saturated fats

•Saturated refers to the number of hydrogens that can fit on the macromolecule

Proteins •Made of small carbon compounds

•Made of amino acids ▫Think DNA

•Used in every function of your body!

•10,000 different proteins

Proteins

•Transport substances

•Speed Reactions•Provide structural support

•Make hormones

Nucleic Acids

•Store and communicate genetic information

• made of carbon, nitrogren, oxygen, phosphorus, and hydrogen atoms

Notes To Notes Card •Write your name and period on the note

card, and use your notes to answer the following questions:

1. What are the four main macromolecules?

2. Which macromolecules provide structural support?

3. What is a macromolecule?4. Which fat is the good kind of fat? 5. What type of macromolecule is used

for barriers, like in honeycomb?
