Chapter 12 : Respiration

Question 1

Describe how ATP is made in mitochondria. [6 marks]

Answer 1

1. substrate level phosphorylation / ATP produced in Krebs cycle
2. Krebs cycle / link reaction produces reduced co-enzyme / reduced NAD / reduced FAD
3. electrons released from reduced / coenzymes / NAD / FAD
4. electrons pass along carriers / through electron transport chain / through series of redox reactions
5. energy released
6. ADP / ADP + Pi
7. Protons move into intermembrane space
8. ATP synthase

Question 2

Plants produce ATP
