Exchange of the respiratory gases between organism and environment is termed as:
Correct answer: C. External respiration
- A. Cell Respiration
- B. Glycolysis
- C. External respiration
- D. Alcoholic fermentation
Explanation
External respiration involves the exchange of respiratory gases (oxygen and carbon dioxide) between the organism and the external environment, typically occurring in the lungs or gills.

About Bioenergetics
Cellular respiration explains how cells release energy from glucose through glycolysis, the link reaction, Krebs cycle and electron transport chain. It includes ATP production, substrate-level and oxidative phosphorylation, aerobic versus anaerobic respiration, and the roles of mitochondria, oxygen and fermentation in energy transfer.
