compounds? Write some reasons in your notebook.

Let’s get a sense of scale: How Do Molecules & Atoms Relate to Cells?

Zoom In

Zoom in…

A Single Organelle (chloroplast) in the CellPLANT CELLS

A Single Molecule inside the Organelle (chlorophyll)

Atoms come together to make up molecules

Zoom in a lot more…

What elements do you see in the atoms that make up this molecule?

Six Common Elements in Living Things:

Carbon (C) Hydrogen (H) Nitrogen (N) Oxygen (O) Phosphorus (P) Sulfur (S)

CHNOPS

Objectives for Class: Identify the 6 key elements found in living things Explain how monomers and polymers relate to each other Identify examples of foods that contain carbohydrates Identify two key functions of carbohydrates in food

Carbon: The “Swiss Army Knife” Element of Life

More versatile than any other element! Can bond with itself and many other elements Forms millions of large molecules

Monomer – a single, building-block molecule based on carbon

Polymer (a.k.a. Macromolecule)– “Many monomers” a long chain of monomers bonded together to form one huge molecule

Objectives for Class: Identify the 6 key elements found in living things Explain how monomers and polymers relate to each other Identify examples of foods that contain carbohydrates Identify two key functions of carbohydrates in food

4 Types of Carbon-Based Compounds:

Carbon combines with Hydrogen, Nitrogen, Oxygen, Phosphorus, and Sulfur to form these 4 Compounds:

Carbohydrates Lipids Proteins Nucleic Acids

Each type is made of monomers that connect to form polymers.

IMPORTANT NOTE: Each type is separate – not made of each other! Lipids are not made of carbs!]Objectives for Class:

Identify the 6 key elements found in living things Explain how monomers and polymers relate to each other Identify examples of foods that contain carbohydrates Identify two key functions of carbohydrates in food

Carbohydrates contain C-H2O

Simple sugars Monosaccharide = one sugar

Ex: glucose, fructose Disaccharide = double sugar

Ex: sucrose, lactose, maltose Used as an immediate energy

source(for cell respiration to make ATP)

Foods: sugar, fruit, candy, juice, sodaObjectives for Class: Identify the 6 key elements found in living things Explain how monomers and polymers relate to each other Identify examples of foods that contain carbohydrates Identify two key functions of carbohydrates in food

More Carbohydrates

Complex sugars Polysaccharide = many sugars Can be used for:

Long-term energy storageEx: Starch

Foods: grains, root vegetables (bread, pasta, cereal, rice, corn, potatoes)

Structural supportEx: cellulose (plant cell walls) (aka “fiber”)

Foods: fruits, vegetables, whole grains (lettuce, celery, whole wheat)Objectives for Class:

What Foods Contain Proteins?

Objectives for Class: Identify examples of foods that contain proteins Identify two key functions of proteins Describe the monomers and polymers of proteins

Have thousands of different uses!

Proteins can be… Enzymes (control chemical reactions) Hormones (ex: insulin) Transporters

in cell membranes in blood cells (hemoglobin)

Body structures (hair, muscle, skin, bone) Immune system (fight diseases)

Proteins contain C, H, O, N and some S


Proteins are made of: Amino acids

(monomers) There are 20 different

amino acids (different R’s)

Thousands of A.A.’s connect in any possible order to form long chains this makes thousands of different possible proteins

How can there be so many Different Proteins?

Today’s Objectives: Follow lab safety guidelines and lab procedures Predict which carbon compounds are in a Happy Meal Use chemical indicators to test the compounds in a

Happy Meal

Bio 9B: Thursday, 10.22.09Title: The McMush Lab

Double Block

The World Famous McMush Lab… Important Terms and Concepts I

What are chemical Indicators? Chemicals that indicate the presence of a certain substance by changing color when they

are in contact with that substance. A change in color = Positive Result (the substance is there) NO change in color = Negative Result (the substance is NOT there)

3 Chemical Indicators in this Lab: Benedicts Solution: Changes color when it comes in contact with a Monosaccharide like

Glucose Iodine: Changes color when it comes in contact with a Polysaccharide like Starch Buiret Solution: Changes color when it comes in contact with a Protein

Negative Control = Water The variable that is the same for all test trials. It is guaranteed to give a Negative Result Why use water?

Why must we do Part I BEFORE Part II? What does Part I tell us so that we can do Part II?

Note: in Part II you are completing the SAME procedures for Part I, BUT you are using McMush instead of the pure solutions… so for every test, you will test the McMush and the Water

Procedural Notes: Each team member should be the leader for 2 of the 4 tests When using the Hot Plate and Boiling the water - NO Messing Around

The World Famous McMush Lab… Important Terms and Concepts II

Using the well plate for the protein and starch tests Use 2 wells for the Protein Test

(one for the pure protein, the other for Water) Use 2 wells for the Protein Test

(one for the Starch, the other for Water)Protein Solution + Biuret Indicator

Water in Protein Test + Biuret Indicator

Starch Solution + Iodine IndicatorWater in Protein Test + Iodine Indicator

Part III: Draw a picture of your meal on a larger piece of paper Label the Carbohydrates, Proteins and Lipids on the

picture Under each Label




Objectives for Class: Explain the difference between reactants and products in a chemical reaction Explain how an enzyme’s structure fits it function

Some new Vocab: Chemical Reaction: Process that changes or

transforms one set of chemicals into another Reactants: compounds that enter the chemical

reaction Products: compounds that are produced in the

chemical reaction Catalyst: Something that speeds up a chemical

reaction Either to build something – Synthesis Or to break something – Decomposition

Introduction to Enzymes: “Chemical Reaction Vocab”

See Handout for accompanying notes to guide website visuals: ..\enzymes\PHA_Bio9_Enzyme_notes_lewport link_09-10.doc


See Handout for accompanying notes to guide website visuals: ..\enzymes\PHA_Bio9_Enzyme_notes_lewport link_09-10.doc

Some More Vocab: Enzymes: Proteins that speed up reactions

(the “catalyst”) Substrate: The reactants in a chemical

reaction



Let’s take a reaction we have seen a few times to illustrate the vocabulary…


glucose + oxygen carbon dioxide + water + ATP energy + heat

Substrates/ Reactants = Stuff Entering a Chemical Reaction

Products = Stuff Produced from a Chemical Reaction

Introduction to Enzymes: “Enzyme catalyzed reaction”


Enzyme = Protein that “Speeds Up” a Chemical Reaction

Enzymes are a “catalyst”

Products = Stuff Produced from a Chemical Reaction “Enzyme – Substrate

Complex”

Substrate = Reactants of a Chemical Reaction

“Bonding Site” – where the substrate bonds to the enzyme

This shows the reaction happening!!!
