Question

Write down 3-processes of Respiration is carried out in humans explain these 3-steps in detail ?​

Answer 1

The steps involved in respiration are as follows:

Pulmonary ventilation or breathing through which atmospheric air is drawn in and carbon dioxide-rich air is given out

Diffusion of gases across the alveolar membrane

Gaseous transport by the blood

Diffusion of carbon dioxide and oxygen between tissues and blood

Oxygen is used by cells for catabolic reactions and resultant release of carbon dioxide

Answer 2

Cellular respiration is a metabolic pathway that breaks down glucose and produces ATP. The stages of cellular respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation.
