Cofactor is Mg

Question 2

Phosphorylase

Answer 2

Phosphorylates substrate using free phosphate (Pi)

Question 3

Isomerase

Answer 3

Create isomer of substrate and has the same chemical make-up but a different structure

Question 4

Epimerase

Answer 4

Create epimer of substrate and has the same chemical make-up and structure but differ around one chiral carbon

Question 5

Mutase

Answer 5

Moves a side chain from one carbon to the next

Question 6

Transferase

Answer 6

Transfer a side chain from one substrate to another

Question 7

Transaminase

Answer 7

Involved in transferring amino groups from or onto amino acids

Question 8

Lyase

Answer 8

Cuts carbon-carbon bonds

ATP must be used

Question 9

Carboxylase

Answer 9

Use CO2 to create carbon-carbon bond

Use ATP

Cofactor is B7

Question 10

Synthase

Answer 10

Multiple substrates are stacked together to create a product

no bonds are broken

Question 11

Synthetase

Answer 11

Multiple substrates are stacked to create a product

no bonds are broken

ATP is used

Question 12

Dehydrogenase

Answer 12

Cofactors are used

Someone is going to lose a hydrogen

Question 13

Hydrolase
