A polymer of amino acids folded in a unique way to preform a unique function.
What is a protein.
200
The group of biomolecules which contain hormones such as testosterone and estrogen. Sketch the general shape of these steroids.
What are lipids.
200
The term for the process enzymes use to make reactions speed up. (And they do that by reducing the amount of activation energy.)
What is catalyze. They reduce the amount of activation energy needed.
200
Draw the pH scale, label the neutral, acidic, and basic regions.

Surface tension in water is caused by adhesion or cohesion?
Cohesion.
400
The type of bond that would form when two atoms share a pair of electrons.
What is covalent. (Only nonmetals do this, and this is the intramolecular bond, they hold organic molecules together)
400

500
This group of biomolecule forms enzymes that have specific shapes so they can catalyze specific reactions.
What is protein.
500
The term that describes what happens if an enzyme (or any protein) heats up too much and it permanently changes shape and looses its function.
What is denature.
