Answer:
Most of the ATP energy obtained from cellular respiration is produced in the third and final stage, the electron transport chain.
Answer:
Some very common examples are a lion (predator) and a zebra (pray) or a bear (predator) and a salmon (pray).
Explanation:
A predator is an organism (plant or animal) that eats another organism (plant or animal). The prey is the organism that is eaten by the predator. Which means the predator is the thing eating the pray.
Answer:
The process that does not require oxygen is fermentation.
Explanation:
Fermentation is an alternative route of cellular respiration for obtaining energy, in the absence of oxygen. In aerobic respiration, oxygen is the acceptor of electrons from NADH but, in anaerobic respiration, the electron acceptor is an organic compound.
The fermentation process does not occur in the mitochondria nor does it involve the electron transport chain, and has a low energy yield at the end of the process.
With respect to the other options:
- <em>The </em><em><u>electron transport chain</u></em><em> and the </em><em><u>Krebs cycle</u></em><em> occur in the presence of oxygen.</em>
