|
Term
1. Compare the process of respiration with the process of photosynthesis. |
|
Definition
Essentially, respiration and photosynthesis are opposites. Respiration produces water and carbon dioxide from food and oxygen. Photosynthesis produces food and releases oxygen as a by-product |
|
|
Term
2. Why do most complex organisms undergo aerobic respiration rather than anaerobic respiration? |
|
Definition
More energy is released, allowing complex organisms to sustain themselves. Anaerobic respiration does not release enough energy for complex organisms |
|
|
Term
. Distinguish between anaerobic and aerobic respiration. |
|
Definition
Anaerobic respiration occurs in the absence of oxygen, aerobic in the presence of oxygen. Aerobic respiration releases more energy than anaerobic respiration and occurs in the mitochondria |
