Transcript of Macro-molecules - 7th Grade

Page 15 in ISN (page 97-101 in textbook)
On page 14, describe/explain the Macromolecules lesson in your own words. You can use charts and/or diagrams.
What are cells made of, and is it food?
Thank you!

By: Mr. Begoyan
Cells are the building blocks of life, nothing alive is smaller than a cell.
Yet cells are made of smaller parts, smaller building blocks.
These building blocks are not alive, yet everything alive is built from them.
These building blocks are known as Macromolecules (Macro = Large)

Smaller than a cell, not alive, yet very important!

Primary Function:

-Food source.
-Short/medium term energy storage.

Secondary Function:
-Cell marker.

2 types
-Simple: Sugar (glucose, sucrose, fructose)
-Complex: Starch (potato, grain, bread, pasta)

1. What is a Macromolecule?

2. All life on Earth is based on this element ____________.

3. What does it mean to be an organic molecule?

4. List the 4 types of Macromolecules.

5. What are the primary and secondary functions of Carbohydrates?

Questions (no you don’t have to write this...)

Primary Function:
-Involved in all cell functions.
-They are little workers that make everything happen (fix, repair, transport, make, fight).
-Biological catalysts (enzymes).

Secondary Function:


Primary Function:
-Long term energy storage.
-Structure: primary component of cell membranes.
-Cushions body parts.

Secondary Function:
-Hormones (chemical messengers).


-Primary Function:
-Makes up DNA (Deoxyribonucleic acid) and RNA (Ribonucleic acid)
-Made of individual parts known as nucleotides.
-Each nucleotide is composed of a
, a
, and a
nitrogen base.

Nucleic Acid


All life on Earth is Carbon (C) based.
Anything that contains Carbon is an organic molecule.
There are four types of biological Macromolecules:
Carbohydrate, Protein, Lipid, Nucleic Acid.
All four contain large amounts of
Carbon (C)
, and thus are all
organic molecules.

Carbon Based Life
1. What are the primary and secondary functions of Proteins?

2. What are the primary and secondary functions of Lipids?
3. What are the primary and

secondary functions of

Nucleic Acids?

4. Nucleic Acids are made

of individual units called
