Objectives and Main Questions

​Found in vegetables, fruits, bread and pasta

Energy! Burns fast. Made of monosaccharides.

​​Carbohydrates

​Found in meat, nuts, beans, eggs.

Assist with tons of things in your body. Made of amino acids.

​​Protein

Found in fats and oil.



Long term energy! Made of glycerol and fatty acids.

​​Lipids

What does that look like?

A monomer is a single building block that makes up something larger. Our biomolecules are built of many building blocks.

What's a monomer?

Monomers

Multiple Choice

What's a monomer?

• Building block that makes up something

• A single element

• A single molecule

• A biomolecule

Match

Match the biomolecule with its monomer (building block)

• Carbohydrates

• Protein

• Lipids

• Nucleic Acid

Monosaccharides

Amino Acid

Glycerol and fatty acids

Nucleotide

• Monosaccharides

• Amino Acid

• Glycerol and fatty acids

• Nucleotide

Glucose is an example of a

Poll

My favorite biomolecule to eat is:

• Proteins

• Lipids

• Carbohydrates

• NUCLEIC ACIDS

Our biomolecules are built of monomers of things like glucose. But those are made of elements. And what are elements made of?? And what's an element???

​

But what are the building blocks built with?

Multiple Choice

Wait, we know this. WHAT'S EVERYTHING IN THE WHOLE UNIVERSE MADE OF?

• Atoms

• Proteins

• Dark matter

• Hydrogen

The building block of the whole universe.

Atoms have:
Protons (positively charged particles)
Neutrons (neutral particles)
Electrons (negatively charged particles)

Atoms ->

Those things on the periodic table, like Oxygen, Hydrogen, Helium, and Iron.

Elements combine to form molecules, like H2O (water!). They are classed into different groups, like metals and noble gases.

Elements - >

Molecules are elements basically stuck together. You built some in PhET.

They can be arranged tons of different ways to form different kinds of molecules.

H2O? Water. H2O2? Hydrogen peroxide.

Why are biomolecules important?

Multiple Choice

In biology, ATP is

• Energy

• At the top

• Proteins

​We are heterotrophs, so we eat stuff to get energy. That stuff? Biomolecules.

We use those to make ATP, which is like energy currency for our body. We breathe out CO2, which plants need to make energy.

​​Animals

Plants are autotrophs, so they make their own energy using photosynthesis. They just need sunlight, water, and CO2 to make glucose and oxygen!

We use that glucose and oxygen to make energy.

Why do plants and animals need each other to survive?

Biomolecules are made of elements and are used to get energy. Plants and animals use the products of each other to get energy.
