1
Q
What is a catalyst
A
a substance that increases the rate of chemical reactions and is not changed by the reaction
2
Q
what are enzymes
A
they are proteins that are involved in all metabolic reactions and function as biological catalysts
3
Q
why are enzymes required
A
they are crucial since they speed up metabolic reactions which would take too long otherwise
4
Q
what is an active site
A
each enzyme has an active site that is complementary to the substrate
5
Q
what happens when the enzyme substrate complex is created
A
the substrate enters the active site and gets broken down
6
Q
can an enzyme break down multiple substrates
