100
the subatomic particles responsible for the chemical behavior of atoms
What are electrons?
100
Ca2+ is an example of __ and the 2+ means...
an ion... it has lost 2 electrons
100
As this lowers, the hydrogen ion concentration becomes greater.
What is pH?
200
the molecule that contains high energy phosphate bonds, and which macromolecule is it
What is ATP (adenosine triphosphate) and nucleic acid
200
the type of energy that causes the breakdown of glucose to simpler forms
What is chemical energy?
200
when a pair of electrons is shared unequally between two atoms
What is a polar covalent bond?
200
the number of valence electrons of oxygen
6
200
This is a good solvent, it has a high heat capacity, and it is a chemical reactant
What is water?
300
What is the quarternary structure of proteins?
What is combining subunits?
300
positive charge, 1 atomic mass unit, in the nucleus
What is a proton?
300
two or more atoms or molecules monomers to form a polymer (what type of reaction?)
What is a dehydration synthesis?
300
atoms that have the same number of protons and electrons but vary in the number of neutrons they contain
What is an isotope?
300
Has NH2 at one end and COOH (carboxylic acid on the other)
What is an amino acid?
400
What is it called when proteins lose their shape, and what are 2 factors that can make proteins lose their shape?
proteins DENATURE. 3 factors: heat, acid/base
400
Atoms are neutral, so they must contain equal numbers of these.
What are protons and electrons?
400
Water does not mix with oil because
polar likes polar and nonpolar likes nonpolar
400
water is a polar molecule because
the oxygen pulls the electrons more strongly than the hydrogens (electrons spend more time around the oxygen than around the hydrogens)
400
made up of a nitrogen-containing base, a sugar molecule, and a phosphate group
What is a nucleotide?
500
two examples of polysaccharides.
What are starch and glycogen?
500
element that is present in all organic compounds
What is carbon?
500
the attraction between oppositely charged particles that occurs following a complete loss or gain of electrons
What is an ionic bond?
500
C-14 breaks down over time because .... and what is this process called?
of radioactive decay -- non-stable conformation
