Enzyme that breaks down cellulose found in cow stomachs.

Question 4

Sucrase

Answer 4

Breaks down sucrose into glucose and fructose.

Question 5

CaM Kinase

Answer 5

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

Question 6

PKA

Answer 6

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

Question 7

ERK

Answer 7

Phosphatase

Answer 11

Removes the phosphates from molecules in a cell.

Question 12

Adenylyl Cyclase

Answer 12

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

Question 13

Phosphodiesterase

Answer 13

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

Question 14

Sodium-Potassium Pump

Answer 14

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