- 24Outline the process of the Krebs cycle
- 25What happens to the coenzyme A?Coenzyme A is recycled between the link reaction and the Krebs cycle
- 26What are the products of one Krebs cycle?1 coenzyme A
Oxaloacetate
2 CO₂
1 ATP
3 redNAD
1 redFAD - 27Which process is the coenzyme A produced in one Krebs cycle used in?Reused in the next link reaction

- 33Complete the sentence: So far (in the first 3 stages of aerobic respiration), ___ ATP are produced from _________-level _______________So far (in the first 3 stages of aerobic respiration), 4 ATP are produced from SUBSTRATE-level PHOSPHORYLATION
- 34Outline the electron transport chain in oxidative phosphorylation1. redNAD releases hydrogen by dehydrogenation
2. Each hydrogen atom is split into a H⁺ and an e⁻
3. The electrons pass through a series of proteins embedded in the inner mitochondrial membrane
4. redFAD releases hydrogen by dehydrogenation
5. The transfer of electrons from the electron carriers to the protein complex changes the shape of the protein, creating a channel that allows H⁺ to flow from the matrix to the intermembrane space
6. There is more H⁺ in the intermembrane space than the matrix
7. An electrochemical gradient is set up. This is also known as the proton-motive force
8. The electrons are passed onto the next protein complex in the inner mitochondrial membrane, causing it to be reduced while the previous one is oxidised
9. The electrons are passed onto the final protein complex, causing it to be reduced whilst the previous one is oxidised - 35Outline the process whereby ATP is synthesised by ATP synthase1. H⁺ in the intermembrane space move down their electrochemical gradient
2. This causes ATP synthase (in the inner mitochondrial membrane) to spin, creating enough energy to catalyse the phosphorylation of ADP to produce ATP (ADP + Pi --> ATP)
3. The H⁺ ions are released back into the matrix where it is transported into the intermembrane space again or reacted with oxygen to form water
4. oxNAD and oxFAD are recycled and used in glycolysis, the link reaction and the Krebs cycle
5. The process in which energy from a proton gradient is used to make ATP is called chemiosmosis
