Periodic Table
What makes up an atom of any element? Hint: 3 subatomic particles.
Protons, neutrons, electrons
the process by which atoms or groups of atoms are reorganized into different substances.
Chemical Reaction
On the pH scale, what is considered a base?
8-14
A type of bond in which electrons are evenly shared.
covalent
True or False: In a chemical reaction there are more products than reactants.
False
What tells us the number of protons and electrons on the periodic table?
Atomic Number
The specific location on the enzyme where the substrate binds
active site
When dissolved in water, H+ ions are released.
Acids
A weak bond formed between a hydrogen atom and a fluorine, oxygen, or nitrogen atom.
Which side of the equation is the reactant side?
What are valence electrons?
Daily Double: How do you figure out valance electrons with the periodic table?
Outermost electrons
Count the groups/vertical columns
mixtures that can react with acids or bases to keep the pH within a particular range.
buffer
A solution is considered what type of mixture?
Homogeneous
Hydrogen bonds allow for this property of water in which water molecules stick to other things like the walls of a glass container.
adhesion
An exothermic reaction is one in which energy is ________ during the reaction.
released
If hydrogen and oxygen form a bond, what type of bond is it?
Covalent
atoms of the same element that have different numbers of neutrons in the nucleus.
isotopes
name 2 factors that impact enzyme function.
Daily double: Explain why they impact enzyme function.
pH and Temp.
Optimal conditions- if they are too high or low the enzyme will become denatured and the substrate will not fit.
Attraction between molecules of the same substance. Example: water sticks to water
cohesion
The energy need to start a reaction.
Activation energy
a pure substance that cannot be broken down into other substances by physical or chemical means.
element
This substance dissolves other substances. Ex. Water dissolves sugar. What is water considered?
Solvent
In this chemical reaction, what are the products?
CH4 + O2→ CO2 + H2O
CO2 and H2O
A bond in which electrons are shared unevenly leaving one side of the molecule with a slightly positive charge and the other end with a slightly negative charge. Hint: allows for hydrogen bonding to occur.
Polar covalent bond
A Biological catalyst that lowers the activation energy of a reaction.
