ATP is sometimes described as an immediate energy store. Explain why?
Energy release only involves a single reaction
1 of 8
Why can plants not use ATP from photosynthesis as there only source of ATP?
Need more ATP; Photosynthesis cannot produce ATP in dark; Cannot be produced in cells lacking chlorophyll; ATP cannot be transported
2 of 8
How do red blood cells obtain ATP as they have no mitochondria? Why?
Glycolysis because it does not occur in mitochondria, just the cytoplasm
3 of 8
In the presence of oxygen, respiration yields more ATP per molecule of glucose than it does in the absence of oxygen. Explain why?
Oxygen is terminal hydrogen and electron acceptor; oxidative phosphorylation; Pyruvate is used in the kerb cycle; Little ATP is produced in glycolysis
4 of 8
Explain why oxygen is needed for the production of ATP on the cristae of the mitochondrion.
ATP formed as electrons pass along transport chain;
 oxygen is terminal electron acceptor; electrons cannot be passed along electron transport chain if no O2 to 
accept them; forms H2O
5 of 8
When glucose is respired what happened to the energy which is not incorporated into ATP?
Released as heat
6 of 8
When one mole of glucose is respired anaerobically, only 2 moles of ATP are produced. Explain why less energy is released in anaerobic respiration.
glucose only partly broken down
7 of 8
At the end of a race, a sprinter continues to breathe rapidly for some time. Explain the advantages of this.
Lactate has been produced; Oxygen used to break down lactate; To convert it back to pyruvate
