Dehydration Synthesis
|
a building reaction (anabolic) that involves the removal of water
|
|
|
Hydrolysis
|
a reaction that breaks down substances (catabolic) and uses water in the process
|
|
|
Endergonic Reaction
|
a reaction that uses energy
example: photosynthesis |
|
|
Exergonic Reaction
|
a reaction that releases energy
example: respiration |
|
|
Activation Energy
|
Energy needed to start a reaction
|
|
|
Catalyst
|
a substance that alters the rate of a chemical reaction without itself being changed or used up.
|
|
|
Enzymes
|
special protiens that lower the amount of activation energy needed and regulates the rate of the reaction
|
|
|
Substrate
|
the substance on which the enzyme acts (reactants; becomes the product(s)
|
|
|
Active Site
|
special region of the enzyme with a particular shape that will fit its specific substrate
|
|
|
Enzyme-Substrate Complex
|
When the enzyme fits with its substrate during a chemical reaction
|
|
|
Three factors that affect enzyme action
|
Temperature,pH and concentration of substrate
|
|
|
Denaturation
|
the change in the shape of an enzyme causing it to no longer fit its substrate
|
|
|
Inhibitor
|
chemical that interferes with enzyme function
|
|
|
What is the model used to explain enzyme action?
|
lock and key
|
|
|
Products
|
the substaces that are produced during a chemical reaction
|
