Why did your instructor suggest that a chicken egg was similar to a cell?

Back

Chicken eggs have a selectively-permeable membrane that allows certain molecules to pass through.

Front

What molecule will NOT pass through the egg membrane?

Back

Back

WATER, gases like oxygen or carbon dioxide.

Front

Why is the dehydration synthesis reaction important for CLPN monomers and polymers?

Back

All CLPN polymers are built using a dehydration synthesis reaction.

Front

What is one difference between a monomer and a polymer?

Back

Monomer: Small, simple, 'building block'; Polymer: Large, complex, macromolecule (chain of monomers).

Front

Describe one important function of proteins in the human body.

Back

Proteins are important structural (body-building) and functional (body-running) molecules.

Front

What is the primary structure of a protein?

Back

The unique sequence of amino acids chained together to form that specific protein.

Front

How are carbohydrates and lipids similar?

Back

Both can store energy and are found in most foods.
