Get a paper from the front and answer the warm-up questions at the top 1. What is the difference between organic and inorganic molecules? 2. Which molecules is organic? (Circle your choice) CO2 C6H12O6 NH4 H2O 3. What makes something acidic? 4. What makes something a base? 5. Which pH is a neutral, an acid, and a base? a. pH 7= b. pH 11= c. pH 3=

Check your answers 1. Organic molecules have carbon and hydrogen, while inorganic doesn’t have carbon and hydrogen together. 2. Which molecules is organic? (Circle your choice) CO2 C6H12O6 NH4 H2O 3. If the pH is between 0 and 6.9 it is acidic. 4. If the pH is between 7.1 and 14 it is a base. 5. Which pH is a neutral, an acid, and a base? a. pH 7= neutral b. pH 11= base c. pH 3= acid

Let’s fill in our sheet, I know you’re excited

1. There are 6 elements essential for life. They are: C= Carbon H= Hydrogen O= Oxygen N= Nitrogen P= Phosphorous S= Sulfur The most important element is CARBON! It’s most important because Carbon forms the backbone of important molecules.

2. There are 4 important macromolecules (polymers) 3 2. There are 4 important macromolecules (polymers) 3. Macromolecules are made of monomers (subunits)

4. Macromolecules (polymers) are like houses, and monomers are like the bricks used to build it.

5. The 4 macromolecules are: Carbohydrates Lipids Nucleic Acids Proteins

Macromolecules (or polymers) are made of Monomers (aka subunits).

Guided Biochemistry Reading: We’ll read the section together, then answer the questions before we go into the notes.

Guided Biochemistry Reading Questions: 1. What are all living things and food made of? 2. What are the four types of organic molecules? 3. What are carbohydrates and what do we use them for? 4. What are lipids and what do we use them for? 5. What are proteins made of and what do we use them for? 6. What are the monomers of nucleic acids and why are they important? A.L.T. are made of macromolecules There are carbohydrates, lipids, proteins, and nucleic acids Carbs are sugar that provide energy for cells Lipids are fats and oils that are long term energy sources Proteins are made of amino acids and provide cell structure Nucleic acids are made of nucleotides and they provide directions for the cell to live

We’ll fill out the carbohydrates notes together so you know how to fill out the rest of the paper

Carbohydrates Carbohydrates are made of Carbon, Hydrogen, and Oxygen in a 1:2:1 ratio. (1 Carbon to 2 hydrogen to 1 oxygen atoms)

Carbohydrates Monomer= Monosaccharides Many monomers together form a Polysaccharide Examples in plants: Starch = storage Cellulose = structure

Monosaccharide: Glucose Polysaccharide: Starch

This is funny because potatoes are made of starch which is a polysaccharide (complex carb)

Functions: Carbohydrates Energy Structure and Support Monosaccharide= immediate energy Structure and Support Identifiers on the surface of cell membranes.

Now it’s your turn: Go from station to station and collect the information to fill out your note sheet. Once you finish filling out your notes, finish your biochemistry vocabulary paper from last week (this is due tomorrow). If you finish this today Mr. Shimko will check it to give you credit for your work

Placemat activity Procedure: Divide your placemat into 4 sections. Leave room at the top for a creative title Label the sections with the following: Carbohydrates, Lipids, Nucleic Acids, and Proteins Each section needs to have the following: Elements Present in that macromolecule Monomers Examples of that macromolecule 3 Functions of that macromolecule Drawing of the monomer AND polymer 3 pictures of food that have that macromolecule.

Placemat Rubric: Title=1 pt Heading for each section= 8 pts Monomers= 4 pts Correct elements= 4 pts Functions= 8 pts Examples= 4 pts Drawings= 8 pts Pictures of food= 8 pts Neatness and Creativity=5   Total= ______/50
