Enzyme Structure and Function Flashcards
How are Enzymes Named?
Enzymes are somtimes named for their reactions
ie, DNA Polymerase makes polymers of DNA
Hexokinase, hexo = six, kin= adds phosphates
(6 carbons is glucose)
What are the six types of enzymes?
1) Transferase - A + BX = AX + B (x is transfered)
2) Ligase -(join) A + B = AB, ( DNA LIGASE)
3) Oxidoreductase A + B: A: + B ( Transfer Electons)
Oxido = taking electrons away
Reduct= giving electrons
4) Isomerase A -> B turned into an isomer.
5) Hydorlase A + h2O -> B + C
6) Lyase A -> B + C (Generate a double bond or ring structure)
How do enzymes make reactions go faster?
They reduce the Ea or activation energy
What is the active site
the place where the enzyme binds to the substrate.
What does a co-enzymes
Organic carrier molecules. Hold on certain things for an enzymes. NADH is a
What is a co-factor
they participate in catalysis.
DNA Polymerase.
Can Enzymes function on their own?
No, They need help, thru co-factors, (carriers) and co-enzymes, (assist with catalysis)
How do vitamins and minerals help your body?
They provide co-factors and co-enzymes. Vitimans, are organic molecules that can act as either. Minerals are inorganic that mainly act as co-enzymes, except Calcium.
How do enzymes work best?
They work best in their proper environment. Proper pH and temp. Changes in pH or temp can reduce/ eliminate enzyme functionality.
