100
The 3 subparticles of an atom.
What are protons, neutrons, and electrons?
100
This physical property of water is the reason that ice floats on water.
What is density?
100
Carbon has this many unpaired electrons in its outer energy level.
What is 4?
100
These are the substances that are formed during a chemical reaction.
What are products?
100
This is the general term for a substance that lowers the activation energy and increases the rate of a reaction.
What is a catalyst?
200
A pure substance consisting of only 1 type of atom.
What is an element?
200
In a water molecule, the oxygen atom has this kind of charge.
What is slightly negative?
200
These are the 4 carbon-based molecules found in humans.
What are carbohydrates, lipids, proteins, and nucleic acids?
200
This is the amount of energy needed to break a bond.
What is bond energy?
200
This is another word for reactants, when enzymes are involved.
What is substrates?
300
In this bond, electrons are shared.
What is a covalent bond?
300
This kind of bond is what gives water its unique properties of high specific heat, cohesive, and adhesive.
What is hydrogen bond?
300
Nucleic acids are polymers made up of this monomer.
What is nucleotide?
300
This is the amount of energy needed to start a reaction.
What is activation energy?
300
This is where the substrates bind to the enzyme.
What is the active site?
400
A pure substance that consists of atoms of different elements bonded together in a specific ratio.
What is a compound?
400
In a solution, this is the substance that is present in a greater amount, and dissolves the other substance.
What is a solvent?
400
This is an example of a simple sugar.
What is glucose or fructose?
400
Reactions reach this state when the reactants and products are formed at the same rate.
What is chemical equilibrium?
400
These are 2 factors that can affect the shape and function of proteins like enzymes.
What are pH and temperature?
500
Hydrogen's outer energy level can hold up to 2 electrons, whereas oxygen's outermost energy level can hold up to this number of electrons.
What is 8?
500
A substance that removes a proton (H+) from a solution.
What is a base?
500
Fats and oils are composed of a glycerol bonded to these molecules.
What are fatty acids?
500
This type of reaction absorbs energy.
What is an endothermic reaction?
500
This is an enzyme found in your saliva that helps to break down starches quickly.
What is amylase?
