CHEMICAL REACTIONS
|
either
-forms new bonds OR -breaks existing bonds |
|
|
CHEMICAL REACTION
|
REACTANTS
-(material going into a reaction) -are rearranged to form 1 or more PRODUCTS -(materials coming out of a reaction) which constitutes: METABOLISM -(all the reactions that are occuring at one time |
|
|
ENERGY
|
power to do work
|
|
|
Work
|
change in mass or distance
|
|
|
KINETIC ENERGY
|
energy of motion
|
|
|
POTENTIAL ENERGY
|
stored energy
ie-chemical energy (potential energy stored in chem bonds) |
|
|
4 TYPES OF CHEMICAL REACTIONS
|
1. DECOMPOSITION REACTION
(CATABOLISM) 2. synethesis reaction (anabolism) 3. Exchange reaction 4. reversible reaction |
|
|
TYPES Of CHEM REACTION
|
Decomposition reaction (catabolism)
*cations DONATE electrons -breaks chemical bonds ie-hydrolysis water used to break apart a compound. ie- in digestive tract, food is broken down |
|
|
TYPES OF CHEM REACTION
|
Synthesis reaction (anabolism)
*anabolism accepts electrons -forms chemical bonds ie-dehydration (losing water to create synthesis)= condensation reaction. *formation of water from H & O molecules |
|
|
TYPES OF CHEM REACTION
|
Exchange reaction
-involves decomp 1st, then synthesis *breaking apart compounds to create new ones |
|
|
TYPES OF CHEM REACTION
|
Reversible reaction
-seek equilibrium, balancing opposing reaction rates -reaction rates adjust to reach new equilibrium ie- jello |
