Atoms
Positively charged subatomic particles present in the nucleus of atoms.
What are Protons?
A type of interaction (like a bond) between molecules that causes many of the unusual properties of water.
What are Hydrogen Bonds?
Water molecules are attracted to other substances.
What is Adhesion?
A type of organic compound that contains monosaccharides such as glucose.
What are Carbohydrates?
An organic compound, usually a protein, that acts as a biological catalyst
What is an Enzyme?
One of the three basic subatomic particles that has such a small mass that it is not considered significant when calculating the mass of an atom.
What are Electrons?
A type of chemical bond where atoms share electrons
What are Covalent Bonds?
Water molecules are attracted to other water molecules.
What is cohesion?
A type of nucleic acid that stores energy
What is ATP?
Catalysts lower this to increase the speed of chemical reactions
What is Activation Energy?
A biological substance made of joined atoms of two or more different elements and where one of the elements is carbon.
What are Organic Compounds?
A type of chemical bond where electrons are transferred between atoms and the resulting charges cause bonds to form between them
What are Ionic Bonds?
Water molecules can climb up trees.
What is Capillary Action?
A type of organic compound that contain amino acids
What are Proteins?
The reactant(s) in the following chemical reaction: 2H2O2 --> O2 + 2H2O
What is H2O2?
A substance made of a group of atoms, where the electrons in the bonds are shared evenly between the atoms.
What are Non-Polar Molecules?
A neutral Calcium atom has this many valence electrons. Calcium has 20 protons.
What has 2 valence electrons?
The property of water which causes ice to float on water.
What is Expansion?
A macromolecule that contains a double strand of nucleotide polymers and contains genetic information.
What is DNA?
The substance that binds to the active site of an enzyme and goes through a chemical reaction
What is a Reactant (Substrate)?
Atoms of the same element that have different number of neutrons. For example, C-14 and C-12.
