Flashcards in Chapter 2 Vocab Deck (41):
Anything that has mass ans takes up space. the "stuff" of the universe.
When energy is actually doing work. (Moving objects.)
When it is inactive/stored. (like batteries in an unused toy.)
Stored in the bonds of chemical substances.
Results from the movement of charged particles.
directly involved in moving matter.
Travels in waves. X-Rays for example.
All matter is composed of a limited number of substances.
Smallest particle that still remians its special propriety.
Smallest particle in a chemical element. When two or more atoms are chemically combined.
Two or more bases are combined.
Occur whenever atoms combine with or dissociate from other atoms.
The only electrons that are important when considering bonding behavior are those in the outer most shell.
Form when electrons are completely transferred from one atom to another.
When there is no positive of negative charge.
Electrons do not have to be completely lost or gained for atoms to become stable.
Extremely weak bonds formed when a hydrogen atom bound to one electron-hungry nitrogen or oxygen atom is attracted by another electron-hungry atom, and the hydrogen forms a bridge between them.
Occur when two or more atoms or molecules combine to form a larger more complex molecule.
Occur when a molecule is broken down into smaller molecule atoms or ions.
Involve both synthesis and decomposition reactions; bonds are both made and broken down.
Lack Carbon containing compounds.
Carbon containing compounds.
Substances that conduct an electrical current in solution.
hydrogen and oxygen atoms appear in the same ratio as in water.
universal cellular fuel.
single-chain or single ring structures containing 3-7 carbon atoms.
two simple sugars are joined by a synthesis reaction.
long branching chains of linked simple sugars.
large diverse group of organic compounds.
2 types of building blocks fatty acids and glycerol.
always part of the molecule and takes the place of one of the fatty acid chains.
flat molecules formed of four interlocking rings.
most important steroid molecule.
account for over 50 percent of the organic matter in the body.
The building blocks of proteins are small molecules.
functional proteins that act as biological catalysts.
Deoxyribonucleic acid. a major nucleic acid.
