Not all inspired air reaches the alveoli; 150 ml is stopped in the airway leading to the alveoli. This is called dead air space.
Alveoli are the tiny air sacs present all over the lungs. These are supposed to increase the surface area of the lungs so as to increase the amount of inhaled air. The exchange of oxygen and carbon dioxide takes place through these alveoli.
Dead air space is the unventilated area where air circulation does not take place. This air is supposed to be get trapped somewhere in the respiratory pathway or it reaches an alveoli that is poorly perfused. The dead air space can be of two types: anatomical dead space and physiologic dead space.

For mutations to affect an organism's descendants, they must: 1) occur in cells that produce the next generation, and 2) affect the hereditary material. Ultimately, the interplay between inherited mutations and environmental pressures generates diversity among species.
Answer:
Fermentation is a chemical process that occurs in the cytoplasm since it is anaerobic, that is, with the absence of oxygen.
Explanation:
This anaerobic process is due to the consumption of carbohydrates in the absence of oxygen compared to intense muscular demands such as high-performance physical activity, that is why the obtaining of energy is high, since the purpose is not to anabolize but to catalyze hydrates in order to obtain the energy currency that is ATP and thus produce the contraction of the muscular sarcomero by the union of myosin with actin.
