Definitions
Amino Acids
What are the basic building blocks of protein each containing a carboxyl group and an amino acid
These are involved in almost every chemical reaction that supports life
What are proteins?
protons, neutrons, electrons
what are 3 subatomic particles
catalyst
what is a substance that alters the speed of a chemical reaction but is not used up in the process
Nucleotides
What are the building blocks of DNA and RNA?
Steroid
What is a lipid molecule with four fused carbon rings
Many amino acids bonded together forming part of a protein or the whole protein
What is polypeptide
a number of chemical elements arranged in order of atomic number
What is the periodic table?
a positively or negatively charged atom, or a group of atoms, resulting from the transfer of electrons
What is an Ion?
Biosynthesis
What is the process by which living organisms produce larger molecules from smaller ones?
Lacking any affinity to water, from the latin meaning "water fearing"
What is hydrophobic?
Provide structural support for cells
What are carbohydrates?
Heat Capacity
What is the amount of heat energy required to increase the temperature?
Aqueous Solution
What is a solution in which water is the solvent?
What is matter?
Organic Molecules
What are molecules found in living organisms that contain carbon in rings or long chains, attached to other atoms like hydrogen, oxygen, nitrogen, sulfur, and phosphorus?
Denaturation
What is the process in which the normal shape of a protein is lost, usually due to heat?
Six biologically important elements
What are Carbon, Hydrogen, Nitrogen, Oxygen, Phosphorus, Sulfur?
Hydrogen Bonds
What is a weak electrical attraction between a partially positive hydrogen atom and a partially negative atom of another molecule?
Four main groups of organic molecules
What are carbohydrates, lipids, proteins, nucleic acids
Solute
What is a dissolved substance?
Acts as a chemical signal to carry messages from one cell to another
What is a protein?
The number of protons in an atom
What is the atomic number?
A covalent bond that links amino acids together in a polypeptide
What is a peptide bond?
Compound
What is a molecule that contains atoms of at least two different elements?
