What are the 3 charges of the particles that make up an atom?
Protons - positive
Neutron - Neutral
Electrons - negative
200
What is the difference between cohesion & adhesion?
cohesion: an attraction between molecules of the same substance
adhesion: a force of attraction between different kinds of molecules
200
The hydrogen end of water has a
slight positive charge
200
What is the monomers of Proteins
Amino acids
200
Name the 4 elements of macromolecules.
Carbohydrates, Lipids, Proteins, and Nucliec acids
200
Define active site
The place where the substrate binds
200
Define Allosteric Site.
When a Noncompetitive inhibitor changes the shape of the enzyme, so the substrate cannot bind to the enzyme.

Letter D is the mass number of an element that tells you the average mass of the isotopes of the element. It also tells you the number of ____________ and ____________ in the nucleus of the atom
protons and neutrons
300
Water rising in a tube is an example of what property?
capillary action
300
The oxygen end of a water molecule has a
slight negative charge
300
What is the main function of carbohydrates?
Short-term energy source
300
What are the monomers of Nucleic acids?
Nucleotides
Make DNA and RNA
300
Define denature (as it relates to enzymes)
Anything that changes the shape of an enzyme
300
Define activation energy
The amount of energy it takes for a chemical reaction to occur
400
What two particles in an atom are equal in number.
electrons and protons
400
This causes water to stick to other polar substances besides other water molecules.
adhesion
400
Why are water molecules attracted to each other?
because of polar bonding
400
What is the monomers of carbohydrate?
Monosaccharide
400
What is the main function of Nucleic acid?
Store genetic information
Transfer and carry genetic information
400
Identify the type of inhibition that is taking place. Also, describe this process.
Competitive inhibition. Enzyme active site is blocked causing the substrates unable to bind to the active site.
400
What are four factors that have an effect on enzymes?
pH, Temperature, Salinity, Substrate Concentration
500
These are atoms with the same number of protons but different numbers of neutrons. (Hint: Same element; different mass)
Isotope(s)
500
Which property of water allows a water strider to walk on the surface of the water?
Cohesion or Surface Tension
500
What type of bond is formed from the attraction between the positive end of one water molecule and the negative end of another water molecule?
a hydrogen bond
500
Define Hydrolysis.
Hydrolysis is the process breaking macromolecules down into water.
500
define Polymers:
Polymers many monomers joined together, to form large building.
500
Identify the type of inhibition that is taking place. Also, describe this process.
Noncompetitive inhibition. Something other than substrates binding to the alleostric causing the enzyme to change it shape; substrates are not able to bind to the active site.
