These all are inorganic compounds except:

Correct answer: B. C6H12O6

  • A. NO2
  • B. C6H12O6
  • C. H2O
  • D. H2SO4

Explanation

The correct answer is C6H12O6, which is an organic compound known as glucose. Organic compounds typically contain carbon and are often associated with biological systems. In contrast, the other options-NO2, H2O, and H2SO4-are considered inorganic because they do not contain carbon (except for CO2 and a few other exceptions in inorganic chemistry).

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.
