The partial pressure of oxygen in alveoli of lungs is 104 mm Hg, which is more than that of blood in the blood capillaries of lung alveoli (40 mm Hg)
This difference allows pasive diffusion of from air filled in the lungs to the blood vessels of lung alveloi.

Division of mammalian lungs into a very large number of tiny alveoli around alveolar ducts opening into bronchioles, is:
  1. An inefficient system of ventilation of alveoli though with very little residual air
  2. An inefficient system of ventilating the alveoli resulting in very high percentage of residual air in the lungs
  3. A very efficient system of ventilating the alveoli with no residual air
  4. An efficient system of ventilation of alveoli with little or no residual air

The following observation: when extra oxygen used in the synthesis of glucose from lactate is actually measured, it is always higher than predicted by the stoichiometric relationships. Introduction: In an experiment, the lactate absorbed by the liver is converted into glucose with an input of 6 mol of ATP for every single mole of glucose formed. The extent of this process in a liver of rat preparation was monitored by administering 14 C lactate and measuring the amount of 14 C in the produced glucose.

1.4 Three Domains of life Three domain classification was proposed by Carl Woese (1977) and his co-workers. They classified organisms based on the difference in rRNA genes. The three domain system adds the taxon 'domain' higher than the kingdom. This system emphasizes the separation of Prokaryotes into two domains, Bacteria and Archaea, and all the eukaryotes are THREE DOMAINS (Carl Woese, 1977)
