1

Lysozyme

A clamp shaped enzyme that cuts proteins, most notably bacteria in the mouth.

2

Chaperonin

Binds to unfolded proteins and assists in their proper folding.

3

Cellulase

Enzyme that breaks down cellulose found in cow stomachs.

4

Sucrase

Breaks down sucrose into glucose and fructose.

5

CaM Kinase

Activated by an increase of calcium in the cell. Stimulates ERK.

6

PKA

Activated by cAMP it starts the glycogen breakdown associated with the fight or flight response.

7

ERK

Is stimulated by CaM Kinase and stimulates mitosis or cell growth.

8

Ribosome

Carries out protein synthesis and is found in either the cytosol or on the rough ER.

9

Myosin

Motor protein that facilitates muscle contraction and uses ATP.

10

Dynein

Catalyzes locomotion in cilia and flagella.

11

Phosphatase

Removes the phosphates from molecules in a cell.

12

Adenylyl Cyclase

Converts ATP to cAMP following the activation of G-protein linked receptors.

13

Phosphodiesterase

Converts cAMP to AMP by adding a phosphate group to the molecule.

14

Sodium-Potassium Pump

Found in the cell membrane and pumps sodium out of the cells and potassium in.

15

Flippase

Catalyzes the phospholipid flip-flop about once a month.

16

Hexokinase

First step in the glycolysis cascade.

17

Taq

DNA polymerase, works best at high temperatures.

18

Trypsin

Found in the digestive system. Works on the hydrolysis of peptide chains.

19

Pepsin

Released in the stomach to breakdown foods only at certain pH's near 7-8.
