Term
Synthesis Reaction
Definition
Atoms/molecules combine
energy is absorbed for bond formation
A+B -> AB
Term

Definition
Molecule is broken down
chemical energy is released
AB -> A+B
Term

ex: gastric juice
Term
Bases
Definition
low H+ high OH- ; 8-14 on pH

Definition
monomers build to polymers
water is taken away and the synthesis of molecules occurs

Term
RNA
Definition
ribonucleic acid; A, U, C, G
Term
ATP
Definition
Adenosine triphosphate; chemical energy used by all cells; energy release by breaking phosphate bonds; oxidation replenishes ATP
Term
Anatomy
Definition
the study of structure and shape of body and its parts
Term
Physiology
Definition
the study of how the body and its parts work or function
Term
Levels of organization
Definition
atoms, molecules, cellular, tissue, organ, organ system, organism
