Biomolecules

Identify and describe the function of two out of four biomolecules necessary to life and their importance; Nucleic acid and Protein

Research and explain how the functions of two biomolecules relate to the structures and process that occur in a cell.

I Will:
Student to Teacher

Relate the functions of different types of biomolecules, including carbohydrates, lipids, proteins, and nucleic acids, to the structure and function of a cell. 5A

We will:
Teacher to student.

What are we learning today?

​Unit 2: Building Blocks of Cells & Viruses

Nucleic Acids

Nucleic acids are macromolecules containing the elements…

Carbon, hydrogen, oxygen, nitrogen, and phosphorus

The building blocks of the
nucleic acids are nucleotides.

Nucleic acids
store and
transmit genetic
information.

​

There are two kinds of nucleic acids:
DNA and RNA

Carbon-Based Molecules (Macromolecules)

• Nucleic acids are polymers of monomers called

nucleotides.

​Same thing

2.3 Carbon-Based Molecules TEKS 9A

– Nucleotides are made of a sugar, phosphate

group, and a nitrogen base.

A phosphate group

deoxyribose (sugar)

• Nucleic acids are polymers of monomers called

nucleotides.

​

nitrogen-containing molecule,
called a base

2.3 Carbon-Based Molecules TEKS 9A

– DNA stores genetic

information.

• Nucleic acids are polymers of monomers called

nucleotides.

– Nucleotides are made of a sugar, phosphate

group, and a nitrogen base.

– RNA builds proteins.

Drag labels to their correct position on the image

Phosphate group

Sugar

Nitrogen base

Proteins

Proteins are macromolecules
that contain…

…carbon, hydrogen,
oxygen and nitrogen.

The building
blocks of
proteins
are amino

acids.

There are 20 different amino acids.

Each amino acid has four parts. Label these groups
on the drawing above.

Carboxyl group
An amino group
One single hydrogen

An “R” group which is different on
every single amino acid.

Carboxyl

“R” groups

There are many, many uses for proteins
1.

enzymes

2.

hormones

3.

transport proteins such as hemoglobin

4.

contractile proteins such as in muscle
tissue

5.

antibodies

6.

membrane proteins

7.

structural proteins such as bones and
muscles

One single
hydrogen

​amino

Multiple Choice

Proteins are made of... 

• C H O
• C H O N
• C H O N P
• C H O N S

Poll

How confident are you in your knowledge of macromolecules?

• Not confident, yet. I need to study more.

• Somewhat confident, but I need to study some more.

• I am confident in my knowledge and ready for a test.

• I am so confident that I can teach my peers about it.
