The building blocks of proteins are: amino acids
What is the term for the pocket on an enzyme that a substrate binds to? active site
Type of bond that steals or gives away an electron Ionic bond
Describe the building blocks of a phospholipid: glycerol, phosphate group, and 2 fatty acids
Term for the substance that is dissolved: solute
What is the term for the amount of energy that is needed to start a chemical reaction. Activation energy
What is the term for when smaller molecules combine to make a bigger molecule and removes water dehydration synthesis
Type of bond that is in water, is weak, is covalent, but not sharing equally. Hydrogen bonds
Ice has more ________ hydrogen bonds than water because they are spaced out more. stable
List the parts of the atom and their charges: electron (-), proton (+), neutron
The bond between amino acids to make a protein are called? peptide bonds
Describe the 3 steps of the catalytic cycle (enzyme action) substrate bind, activation energy lowered, enzyme changes shape, products made, products released, active site empty
These have a pH of 8-14. Bases
What are the 3 properties of water: absorbs/stores heat efficiently Bonds to itself and other things Can dissolve substances
What are the 2 primary examples of nucleic acids? DNA and RNA
What is the term for then a non-substrate molecule binds to the active site, not letting the correct substrate bind competitive inhibition
