Cofactors/coenzymes/proshetic group

Question 1

What does it mean by this?

Answer 1

• The addition of a non-protein

Question 2

What are Co-factors?

Answer 2

• INORGANIC molecules or ions
• help the enzyme and substrate to join
• do not directly participate in the reaction
• not used up or changed in the reaction

Question 3

Answer 3

• Organic molecules
• participate in the reaction, altered by it
• act as carriers, moving chemical groups between different enzymes in metabolic pathway.
• continuously re-used and re-cycled

Question 4
