BELL WORK: Copy the question below and write your answer.

Why are biomolecules important?

Set up the next page in your journal…Page: 20Date: 9-22-15Title: CarbohydratesEssential Question: Why are carbohydrates so important?

Yes, Cornell notes!

Biomolecules (Recap)are found in all living things.

are organic compounds.◦ contain the element carbon (C)◦ All living things contain carbon.

A substance without carbon is called inorganic.

Elements to know:C = carbon N = nitrogenH = hydrogen P = phosphorusO = oxygen

Before we begin…Glue the picture in the top left corner of your notes. You will be referring back to it during today’s lesson!

Under the picture, write GLUCOSE and C6H12O6.

Carbohydrates….here we go!Structure discovery:

For the next minute discuss the following questions at your table:

•How would you describe the structure (shape) of this biomolecule?

•What elements are present?

•What pattern exists among the elements? (hint: count them!)

Structure:• typically ring shaped (there are a few exceptions)

• contain Carbon, Hydrogen, and Oxygen (CHO)

•have a 1:2:1 ratio (relationship) in the elements.

o For every 1 Carbon atom, there are 2 Hydrogen atoms and 1 Oxygen atom

QUICK and IMMEDIATE energy

(CAR-bohydrate)

◦contain 4 calories per gram◦there are fewer bonds to break, so the energy is used up QUICKLY

Function:

Examples:

•Saccharides (sugars)oend in –ose (glucose, fructose,

sucrose, etc)

•Vegetables

•Bread

•Starch

Monomer = monosaccharide

Monosaccharides bond to form… Polymer = polysaccharide

What do we call the pieces of a carbohydrate?

Monosaccharide:

Polysaccharide:

MARSHMALLOW’S A-FIRE!

At the bottom of your notes, copy and answer the question below:◦Why did the flame go out before the marshmallow was completely gone?

Use the words carbohydrate, bond, & energy in your answers!

Foldable Time!!!1.Open your journal to page 19. 2.At the bottom of the Monomer box,

write the monomer of a carbohydrate.

3.At the bottom of the Polymer box, write the polymer of a carbohydrate.

4.Draw an arrow from the monomer to the polymer.

5.On the INSIDE of the Carbohydrate door, write TWO functions and FOUR examples.

6.On the FRONT of the Carbohydrate door, draw a glucose molecule. Be sure to draw all the elements!

Reading & QuestionsYou are working INDEPENDENTLY (this means by yourself)!

Read the paragraph and answer the questions.

Anything you don’t finish now is HOMEWORK!
