What are four functions of Lipids in living organisms.

Teacher will verify answer.

300

This is the name of the building blocks of life molecules.

Monomers.

300

What products do we get as the end result of breaking molecules down?

ATP (Energy) and Monomers.

300

Which Polysaccharide is responsible for helping our digestive system?

Cellulose

300

This is the name of a bond between two amino acids.

Peptide Bond.

300

What is the only kind of lipid which can freely interact with water?

Phospholipids.

400

Name the four categories of Macromolecules that exist.

Carbohydrates, Proteins, Lipids, and Nucleic Acids.

400

For what two reasons do we break molecules down?

To get ATP (energy) and to get more building blocks (monomers).

400

When a glucose and a fructose are bonded together, _________ is the result.  This is an example of a ________________

Sucrose Disaccharide.

400

What are 4 main functions of Proteins in our body?

Teacher will verify answers.

400

What are the two main categories or lipids and what are some of the characteristics that make them different?

Saturated and Unsaturated.

Saturated- Solid at room temp, straight chains, unhealthy

Unsaturated- Liquid at room temp, bent chains "kinks", healthy

500

These proteins are responsible for carrying out the reactions that build and break down macromolecules.

Enzymes.

500

List 3 reasons why we build molecules up.

Growth, Repair, and reproduce new cells.

500

Name the 4 kinds of polysaccharides and the functions they perform.

Starch - Plant energy storage

Glycogen - Animal energy storage

Cellulose - Plant structure (Cell wall)

Chitin - Animal/Fungi structure (Exoskeleton)

500

Explain how proteins get their specific shape and how it can be undone.

Hydrophilic and Hydrophobic amino acids align themselves in relation to where water is present.  Raising temp or changing the pH.

500

DAILY DOUBLE:

Explain how phospholipids interactions with water allow them to form a cell membrane.  Then, draw and label a Cell Membrane.

Phosphate HEADS are HYDROPHILIC and orient themselves to the inside and outside of the cell (where water is present).  HYDROPHOBIC TAILS orient themselves between the layers of heads to stay as far away from the water as possible.

Teacher will check the drawing.
