pH
The pH scale measures the concentration of this ion in a solution. The more of this ion that is present, the more acidic the solution is.
H+ ions
All steroids are characterized by this structure.
4 interlocking hydrocarbon rings
This secondary protein structure resembles a coil or a spring.
Alpha helix
This subatomic particle is negatively charged and orbits around the nucleus of an atom.
electrons
This property of water is due to the strength in its hydrogen bonds causing water molecules to strongly attract together.
High surface tension
These solutions can convert strong acids or bases into weak ones by either releasing or binding hydrogen ions.
Buffers
These lipids are known as "fats" in solid form and are known as "oils" in liquid form.
Triglycerides
True or False: enzymes get used up once they act as a catalyst.
False
An element has a mass number of 12 and an atomic number of 5. Therefore it has this many neutrons.
7 neutrons
This type of chemical reactions involve anabolic processes.
Synthesis reactions
The stronger a base is, the more of this ion it will release into a solution.
Hydroxyl (OH-) ion
Monomers are joined together by this process, where an OH group is removed from one monomer and an H is removed from another monomer at the site of bond formation.
Dehydration synthesis
Substrates bind at this location on the enzyme to form the Enzyme-Substrate complex.
active site
Atoms usually desire to have 8 electrons, and this is the driving force behind chemical reactions. This principle is also known as...
the octet rule
This property of water explains why it takes so long to get water to boil.
High heat of vaporization
Because the pH scale is logarithmic, each pH unit represents a difference of this scale.
10-fold
Unsaturated fatty acids are usually liquid at room temperature because of this.
"Kinks" in the carbon chain created by double bonds.
This type of protein is more resistant to denaturation, often providing mechanical and tensile strength.
Fibrous proteins
This type of bond is the result of electron transfer that results in attraction between opposite charges.
Ionic bond
If bonds are BOTH made and broken in a reaction, then this type of reaction has occured.
Exchange reaction
These are the products of a neutralization reactions.
Water and a salt
Prostaglandins are derived from this fatty acid, found in cell membranes.
arachidonic acid
The protein portion of a functional holoenzyme is called this.
Apoenzyme
The bonds in CO2 are formed via even sharing of electrons. Therefore, these bonds are...
nonpolar covalent bonds
Because anabolic reactions result in a net absorption of energy, they are classified as ______ because the products have more potential energy than the reactants.
Endergonic
