what is a catalyst?
|
a chemical reaction in a series of steps, with various intermediate products, which ultimately form the final products of the reaction
|
|
A catalyst provides an ____________ for a reaction to occur. Typically, the catalyst will be involved in on of the "steps" that occur in the reaction, but is reformed before the completion of the reaction, so that the catalyst is not used up.
|
alternate pathway
|
|
The alternate pathway generally allows the reaction to proceed faster, as well as lower the _______ _______.
|
activation energy
|
|
true or false

|
what is activation energy?
|
the energy needed to make a reaction happen
|
|
the energy a reaction needs is usually in the form of ______.
|
heat
|
|
what are inhibitors?
|
slow the rate of reaction
|
|
what is an enzyme?
|
molecules of protein that are made from amino acid chains. they are produced by all living organisms and plants. the structure establishes the functions or uses of enzymes.
