2.8 understand the role of enzymes as biological catalysts in metabolic reactions
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 proteins
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)
The Enzyme remains unchanged
Substrate -----> Product
