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

17

Definition of denatured

It's 3-D shape- Knable to promote chemical reaction
