The atomic number tells us this
What is the number of protons?
A form of an element with a different number of electrons
What is an ion?
Three parts of an atom & their charges
What are the positive proton, neutral neutron, and negative electron?
These make up the atomic mass
What are protons and neutrons?
A form of an element with a different number of neutrons
What is an isotope?
The monomer of a protein
What is an amino acid?
RNA (a nucleic acid) is made of these monomers
What are nucleotides?
Lipids are made of these two components
What are glycerol and fatty acids?
Bonds that hold amino acids together to form long chains
What are peptide bonds?
An example of a polymer of saccharides
What is starch, cellulose, chitin, or glycogen?
The property of water molecules staying together
What is cohesion?
Bonds where electrons are shared
What are covalent bonds?
Water is H2O. What strong bond holds the H and O together?
What is covalent?
A compound is composed of these.
What are molecules?
Sodium chloride has this type of bond
What is ionic bond?
Enzymes are this type of organic compound
What is a protein?
A reaction that gives off energy is called this.
What is exothermic?
This happens to bonds during a chemical reaction.
What is they are broken and formed?
Enzymes can be destroyed (denatured) by these two conditions.
What are temperature and pH?
These kinds of reactions cannot occur without added energy
What are endothermic reactions?
These bonds hold water molecules together and are responsible for cohesion
What are hydrogen bonds?
Salt dissolved in salt water is this part of a solution
What is the solute?
A mixture of water and undissolved particles
What is a suspension?
The liquid part of a solution
What is the solvent?
Daily Double!!
Water can dissolve salts because of this property
What is polarity?
A solution with a pH of less than 7.0
What is as acid?
This is what pH measures.
What is the concentration of hydrogen atoms?
A solution with more H+ than water.
What is an acid?
This is the pH of most soaps (acidic or basic).
What is basic?
Chemicals in the body that help prevent rapid changes of pH.
What are buffers?
Final Jeopardy
Enzymes
Enzymes speed up a reaction because they do this.
What is speed up a reaction by lowering the activation energy
