This is an attraction between molecules of the same substance.
What is cohesion?
100
This process changes or transforms one set of chemicals into another.
What is a chemical reaction?
100
This branch of chemistry concerns itself with compounds that contain bonds between carbon atoms.
What is organic chemistry?
100
This analogy is often used to describe the way a substrate binds to an active site on an enzyme.
What is the lock and key?
200
This is formed by the binding together of protons and neutrons.
What is the nucleus?
200
This special property of water causes water to rise from the roots of plants up through the stem and to the leaves.
What is adhesion?
200
This type of energy is required to get a reaction going.
What is activation energy?
200
This kind of covalent bond is represented by a double line between to carbons. Example: C = C
What is double covalent bond?
200
Humans release energy needed for growth and other biological functions through this process, which is essectially the breakdown and digestion of food.
What is metabolism
300
These are atoms of the same element, but with a different number of neutrons.
What are isotopes?
300
This special quality of water is the result of multiple hydrogen bonds between the molecules that enable water to absorb a lot of heat without changing temperature.
What is heat capacity?
300
Enzymes are made of this type of macromolecule.
What is a protein?
300
These smaller units join together to form polymers.
What is a monomer?
300
These monomers are compounds with an amino group on one end and a carboxyl group on the other end.
What is an amino acid?
400
This kind of compound is formed when atoms join together with covalent bonds.
What is a molecule?
400
This measurement system indicates the concentration of H+ ions in solution.
What is the pH scale?
400
These proteins act as catalysts to chemical reactions in our bodies.
What are enzymes?
400
Plants use this polysaccharide to store excess sugar.
What is a starch?
400
These bonds join amino acids together into a long chain called a polypeptide.
What is a peptide bond?
500
These bonds are formed when an electron or electrons transfer from one atom to another.
What is an ionic bond?
500
This type of substance produces hydroxide ions in solution and has a pH value above 7.
What is a base?
500
These reactants come together at the active site of an enzyme so that they can be transformed by a chemical reaction.
What is a substrate?
500
These monomers consist of a 5-carbon sugar, a phosphate group and a nitrogenous base.
What is a nucleotide?
500
This compound is a nucleotide that plays an important role in capturing and transferring chemical energy.
