Monomer
What do we call the substances that enter a chemical reaction?
Reactants
Acid
Do enzymes speed up or slow down a chemical reaction?
Speed Up
Water is known as the universal ________________, because it is able to dissolve more substances than any other liquid.
Solvent
Monomers join together to form a _________________.
Polymer
What do we call the substances that are produced by a chemical reaction?
Products
If a substance has a high pH level, is it an acid or a base?
Base
Amino acids are monomers for this kind of macromolecule.
Protein
Because of its high heat capacity, water can absorb a large amount of heat without a drastic change in _____________________.
Temperature
This type of macromolecule stores energy, serves as a waterproof covering, and forms cell membranes. Fats and oils belong to this group.
Lipids
What type of macromolecule are enzymes?
Protein
pH level of 2.5
Acid
This type of macromolecule stores genetic information.
Nucleic Acids
This property of water is why water molecules stick to one another and build surface tension.
Cohesion
Sugars are an example of this type of macromolecule.
Carbohydrate
Enzymes bind to a substance called a ________________.
Substrate
pH level of 12
Base
What happens to an enzyme when it is finished with a chemical reaction?
It will find another substrate to bind to.
When water molecules stick to another substance other than water, this is called _______________.
Adhesion
What element is the foundation of all macromolecules?
Carbon
What is the place on the enzyme where the substrate binds called?
Active Site
Is water or an acid or base?
Trick question! Water is neutral, so it is neither an acid nor base.
Enzymes work by lowering the amount of ___________________________ that a chemical reaction needs to get started.
Activation Energy
