Enzymes (1.5) | Edexcel A-level Biology B - 9BI0

Students should:
$i Know the structure of enzymes as globular proteins. ii Understand the concepts of specificity and the induced fit hypothesis. iii Understand that enzymes are catalysts that reduce activation energy. iv Understand how temperature, pH, substrate and enzyme concentration affect the rate of enzyme activity. CORE PRACTICAL 1: Investigate a factor affecting the initial rate of an enzyme-controlled reaction. v Understand how the initial rate of enzyme activity can be measured and why this is important. vi Understand how enzymes can be affected by competitive, non-competitive and end-product inhibition. vii Know that enzymes catalyse a wide range of intracellular reactions as well as extracellular ones.$
