A2 Biology - Respiration 3.0 / 5 based on 2 ratings ? BiologyCellular processesA2/A-levelOCR Created by: Amy CockingCreated on: 26-10-13 16:30 When ATP is hydrolysed to ADP, how much energy is released per mole? 30.6 kj 1 of 20 What does the structure of ATP consist of? 3 phosphates, a pentose sugar (ribose), Adenosine (nitrogenous base) 2 of 20 The 4 stages of respiration? Glycolysis, the Link Reaction, Krebs Cycle, ETC 3 of 20 Which organelle does respiration occur in (aside from glycolysis)? Mitochondria 4 of 20 Where does Glycolysis occur? The cytoplasm of the cell 5 of 20 What structure do the cristae have that have ATP synthase attached? Stalked Particles 6 of 20 What does Glycolysis do? Splits glucose to make pyruvates 7 of 20 What is the net gain of ATP in glycolysis? 2 8 of 20 Where does the link reaction occur? The matrix of the mitochondria 9 of 20 Where does the Krebs Cycle occur? The matrix of the mitochondria 10 of 20 Where does the ETC occur? The cristae 11 of 20 What is NAD? A co-enzyme that picks up hydrogen atoms released and becomes reduced NAD when it has gaines H+ (NADH+) 12 of 20 Which enzymes are used in the Link Reaction and what do they do? Dehydrogenase - removes hydrogen atoms and adds them to NAD Decarboxylase - removes carbon dioxide 13 of 20 How do the pyruvates enter the mitochondria? Via active transport requiring ATP 14 of 20 What is the Carbon Acetate produced in the link reaction carried on to the Krebs cycle? Co-enzyme A, making the compound Acetyl Coenzyme A 15 of 20 Purpose of the Krebs Cycle? Carbon dioxide is lost and hydrogens donated to NAD and FAD, which supplies hydrogen to the ETC 16 of 20 What is ATP used for? Active transport, exocytosis, anabolism, DNA replication, movement of flagellum 17 of 20 Anaerobic respiration Without oxygen 18 of 20 In respiration what is oxygen required for? The ETC as the final electron acceptor 19 of 20 Without oxygen, what stages of respiration stop? ETC, Krebs Cycle and the Link Reaction 20 of 20
