This is a function of an enzyme.
What is speeds-up chemical reactions?
100
An example is when your body runs a fever while fighting-off a pathogen.
What is homeostasis?
200
Property that allows water to absorb a lot of heat with only a small change in temperature.
What is high specific heat?
200
Ion that increases in concentration when an acid dissolves in water, and the ion that increases when a base dissolves in water.
What are H+ and OH-?
200
The macromolecule that is formed from amino acid monomers and plays roles in structure and catalysis.
What is protein?
200
Enzymes speed up reactions by lowering this.
What is activation energy?
200
To become a larger and more complex individual over time.
What is grow and develop?
300
Term that describes water’s ability to dissolve many substances.
What is universal solvent?
300

What is 1,000 times?
300
Exist as simple sugars and polymers and store energy.
What are carbohydrates?
300
The substance that locks into an enzyme at the active site.
What is the substrate?

The basic structure and function of all living things.
What are cells?
400
The reason ice floats on liquid water.
What is the solid form of water is less dense and floats on the liquid form?
400
The stomach has a very low pH to aid digestion. Give an example of a substance that we can ingest (eat, take) that will help with acid indigestion.
What is an antacid?
400
Long Chains of fatty acids attached to a glycerol. Used for energy storage.
What are lipids?
400
Temperature and pH can affect enzyme activity because they can do this to an enzyme.
What is change its shape?
400
An example is when birds fly south for the winter.
What is stimulus and response?
500
How water’s polarity leads to surface tension.
What are hydrogen bonds?
500
The possible effect of acid rain on organisms in a local stream.
What is death?
500
Nucleic acids store genetic information. Name the two primary nucleic acids and state one structural difference between them.
What are DNA and RNA? What is DNA is double-stranded and RNA is single-stranded?
500
The macromolecule group that enzymes are a part of.
What are proteins?
500
The passing of traits from parent to offspring.
What is Heredity?
