A substance that can release hydrogen ions (H+) in detectable amounts. having a sour taste and can dissolve many metals of burn a hole in your rug. pH below 7
Adenosine triphospate (ATP)
Provides a form of chemical energy that all body cells can use. WIthout this, molecules cannot be made or broken down, cells cannot maintain boundaries, and all life processes stop.
small molecules that are the building blocks of proteins.
The sum of the masses of all the protons and neutrons contained in an atoms nucleus.
number given to an element equal to the number of protons its atoms contain.
The building blocks of elements.
Hydroxides ionize and dissociate in water releasing hydroxyl ions (OH-)
Regulates the acid base balance in the body.
Contain carbon, hydrogen and oxygen.
Occur whenever atoms combine with or dissociate from other atoms.
When two or more different atoms bind together to form a molecule.
Bond formed from molecules where atoms share electrons.
Occurs when a molecule is broken down into smaller molecules, atoms or ions. AB->A+B
A water molecule is lost and forms a bond.
nucleic acid found in all living cells:carries the organism's hereditary information.
Substances that conduct an electrical current in solutions.
Orbits or fixed regions of space around the nucleus that electrons occupy.
Negatively charged atomic particles.
Unique substances that cannot be broken down into simpler substances by ordinary chemical methods.
The ability to do work or to put matter into motion.
functional proteins that act as biological catalysts. A catalyst is a substance that increases the rate of a chemical reaction without becoming part of the product or being changed itself.
Involve both synthesis and decomposition reactions. AB+C->AC+B and AB+CD->AD+CB
Extremely weak bonds formed when a hydrogen atom binds to one electron hungry nitrogen or oxygen atom is attracted to another electron hungry atom and a bridge if formed between them.
A water molecule is added to each bond, the bond is broken and releases simple sugars.
Lack carbon and tend to be small, simple molecules.
Bond formed when electrons are completely transferred from one atom to another.
A large group of organic compounds - contain carbon, hydrogen and oxygen with more carbon and hydrogens than oxygens.
Anything that has mass and takes up space.
When two or more atoms combine chemically.
The type of exchange reaction in which an acid and a base interact.
Uncharged, or neutral atomic particles.
Determine what type of or
Carbon containing compounds.
Measures the relative concentration of hydrogen and hydroxyl ions in various solutions.
the main building material of all cells.
Atomic particles with a positive charge.
Process of spontaneous atomic decay.
Heavier isotopes of certain atoms are unstable and tend to decompose to become more stable.
a substance that takes part in and undergoes a chemical change during a reaction.
Atoms with the same number of protons and electrons but vary in the number of neutrons they contain.
the nucleic acids that contains ribose acts in protein synthesis. Present in all living cells. Principal role is to aid as a messenger carrying instructions from DNA for controlling the synthesis of proteins.
the dissolved substance in a solution.
a homogenous mixture of two or more components.
the liquid in which a solute is dissolved to form a solution.
Occur when two or more atoms or molecules combine to form a larger, more complex molecule. A+B->AB
An atoms outermost electron shell.
