Enzymes are
Proteins that promote chemical reactions
1
What are the building blocks of enzymes
Amino acids
2
What organelle is the site of protein synthesis
Ribosomes
3
Each enzyme is ______ for only one substrate or set of substrates
Specific
4
What are substrates
Reactions that need the help of enzymes
5
What is the active site of an enzyme
Binds to the substrate and provides a favorable environment for the reaction to occur
6
During chemical reactions enzymes do not
Change and you're not used up
7
Enzymes may help
Bricktown substrates or combined substrates into new molecules
8
What might happen to an enzyme that is exposed to high temperature or high or low pH
Enzymes, like other proteins, may denature
9
What are the two functions of enzymes
Lower the energy required to activate the reaction
Speed up the reaction
10
Define activation energy
Energy required to get a reaction started
11
Reactants are called
Substrate
12
Enzyme concentration activity
Rate of activity is limited by amount of enzymes available in the cell
13
Substrate concentration activity
Rate of activity is limited by amount of substrate available
14
PH activity
Enzymes can only work within a narrow pH range
15
Temperature activity
Enzymes will only perform under a limited range
16
Inhibitors
Enzyme activity depends on how much competition there is for the active site
