2.8a Enzymes

2.8 understand the role of enzymes as biological catalysts in metabolic reactions

28a Enzymes

1. Catalyst = makes the reaction occur faster under moderate conditions. 
2. Metabolical reactions = biological reactions taking place in a cell, building molecules up or breaking them down. 
3. Lock and Key Hypothesis 
Enzymes have a particular shape 
Enzymes are 

a)  Enzyme

b) Active site - where the substrate (c) fits in. Called: COMPLEMENTARY 
(d) Activated Complex (substrate in active site)
(e) Products emerge from the enzyme (substrate has been broken down into two products) - (f)

Enzyme remains unchanged

Substrate -----> Product
