Exam tips

• Understand enzyme specificity

  Make sure to explain how each enzyme's structure relates to its function, particularly in terms of substrate specificity.

  Understanding the specificity of enzymes helps in answering questions about their roles in digestion accurately.

• Use diagrams to illustrate your answers

  When explaining the structure of the ileum, include labeled diagrams to enhance clarity.

  Visual aids can help convey complex information more effectively and demonstrate your understanding of the topic.

• Use diagrams to illustrate processes

  When explaining co-transport mechanisms, include labeled diagrams to show the movement of ions and molecules across the membrane.

  Visual aids can enhance understanding and retention of complex processes, making it easier to convey the interactions involved in absorption.

• Use diagrams to illustrate concepts
