3. ATP and Energy Flashcards
What is the formula for aerobic respiration?
Glucose + oxygen —> carbon dioxide + water + energy
C6H12O6 + 6O2 —> 6CO2 + 6H2O + energy
What is ATP energy used for?
- anaerobic processes
- body + cell movement
- active transport
- secretion (form and transport vesicles)
- activation of chemicals
What are the benefits of the ATP system?
- doesn’t lose heat
- instantaneous
- a set amount of energy
- doesn’t lose energy if transported or transformed
What is Glycolysis?
The first stage of aerobic respiration, doesn’t require oxygen
Glucose molecules undergo a series of reactions which breaks them into 2 pyruvate molecules
If there is no oxygen, a aerobic respiration occurs. But if there is oxygen, aerobic respiration occurs and there is a net gain of 2 ATP energy
What is the Kreb’s Cycle?
The second stage in aerobic respiration that requires oxygen.
Produces citric acid, oxoglutaric acid and oxaloacetic acid
How much ATP energy is produced by aerobic respiration?
38 molecules of ATP are produced from one glucose molecule. However 2 are used for active transport, giving a net gain of 36 ATP
What are the differences between Aerobic and Anaerobic respiration?
- aerobic takes place in the mitochondria, whereas anaerobic occurs in the cytoplasm
- oxygen is only required for aerobic
- aerobic is more efficient, producing more ATP from the same one glucose molecule
- Aerobic respiration includes an electron transport train
