We will learn how to recognize and draw different organic macromolecules. For now, let's see if you can guess what they do for your body!

Multiple Choice

Organic molecules all contain carbon. What's so special about carbon?

• It's water-soluble

• It can form chemical bonds with up to 4 different atoms

• It's abundant on Earth

• It's polar

Multiple Select

Select all that are made up of molecules.

• sandwiches

• atoms

• people

• chair

Multiple Choice

Which organic compound functions MAINLY to provide short-term energy storage for your body?

• Carbohydrates

• Lipids

• Proteins (Polypeptides)

• Nucleic Acids

Multiple Choice

Where do we get glucose molecules from?

• Sugars/Starches

• Protein

• Air

• Water

What are YOU made of?

• All living things are made of organic macromolecules

• "Organic" = contains carbon and builds living things

• "Macro-" = large

• "molecule" = collection of atoms

Poll

Where is the best place to take in oxygen molecules?

• Mountains

• Beach

• Forest

• Pool

Multiple Select

Select all that contain protein.

• meat

• eggs

• beans

• candy

Open Ended

In your own words how would you describe the metabolism to someone?

Multiple Choice

Which organic compound provides long-term energy storage for your body?

• Carbohydrates

• Lipids

• Proteins (Polypeptides)

• Nucleic Acids

Lipids

Fats, oils, and waxes are all examples of lipids.

Multiple Choice

Which organic compound stores and communicates information in your cells?

• Carbohydrates

• Lipids

• Proteins (Polypeptides)

• Nucleic Acids

Nucleic Acids

DNA and RNA molecules encode the information needed to build and maintain your body.

Proteins

Proteins (polypeptides) are made from building blocks called amino acids. There are 22 types of amino acids! Eating a wide variety of foods is important to make sure your body is getting all essential amino acids.

Multiple Select

Assembling proteins from amino acids (monomers) would be described as... (check all that apply)

• Anabolism

• Catabolism

• Condensation

• Hydrolysis

Multiple Select

Digesting starch (a polysaccharide) into maltose (a disaccharide) subunits would be described as... (check all that apply)

• Anabolism

• Catabolism

• Condensation

• Hydrolysis

Multiple Choice

Last but not least... which of the following is NOT a main function of proteins in your body?

• Structural support

• Membrane transport

• Signalling

• Energy

Metabolism

• The web of all enzyme-catalyzed reactions in a cell or organism.

• Metabolic reactions help macromolecules change between their monomer, dimer, and polymer forms

Metabolism = Anabolism + Catabolism

• Catabolic reactions break complex molecules apart to make simple molecules

• Catabolism relies on hydrolysis reactions

Metabolism = Anabolism + Catabolism

• Anabolic reactions add simple molecules together to make complex molecules

• Anabolism relies on condensation reactions

Multiple Choice

Which image below shows a polysaccharide?

Multiple Choice

Which image below shows a polysaccharide?

Multiple Choice

"-saccharide" is a suffix that means "sugar." Which image below shows a monosaccharide?

The Many Forms of Macromolecules

• Monomer = a single building block or subunit

• Dimer = 2 building blocks (subunits) linked

• Polymer = many building blocks (subunits) linked
