proteins and enzymes

Question 1

describe induced fit model and how enzymes act as catalysts
(3 marks)

Answer 1

• active site and substrate bind/ESC forms
• active site changes shape so substrate is now complementary
• enzymes reduce activation energy

Question 2

explain how active site of enzymes increase rate of reaction

Answer 2

• induced fit model causes active site to change shape
• distorts/stresses/breaks bonds
• reduces activation energy
