Biomolecule Review Worksheet

How are organic molecules related to all living things?

• They exist in all living things and are life's building blocks.

• They are only found in non-living things.

• They are not important for life processes.

• They are only present in plants.

How are the building blocks of organic molecules like bricks?

• They join together to form a large molecule (polymer), just as bricks joined together form a wall.

• They are made of metal, just as bricks are made of clay.

• They are always square-shaped, just like bricks.

• They are used only for decoration, just like bricks in a garden.

What determines how organic molecules will look and behave?

• The arrangement (form) of atoms and functional groups in the molecule.

• The temperature of the environment.
• The size of the molecule.
• The color of the molecule.

What are the four common characteristics of organic molecules?

• 1. All are carbon based. 2. Formed from a few elements. 3. Built from a single type of building block. 4. Their form determines their function.

• 1. All are nitrogen based. 2. Formed from many elements. 3. Built from multiple types of building blocks. 4. Their function determines their form.

• 1. All are oxygen based. 2. Formed from a single element. 3. Built from different types of building blocks. 4. Their form does not determine their function.

• 1. All are hydrogen based. 2. Formed from a few elements. 3. Built from a single type of building block. 4. Their function is unrelated to their form.
