Question

Choose the equation of reaction that correctly represents anaerobic respiration in muscles:

Options

• \[\ce{Glucose -> Pyruvate ->[Absence][of O2] Ethanol + CO2 + Energy}\]

• \[\ce{Glucose ->[O2] Pyruvate ->[O2] Energy}\]

• \[\ce{Glucose ->[O2] Pyruvate ->[Lack of][oxygen] Ethanol + Energy}\]

• \[\ce{Glucose -> Pyruvate ->[Lack of][oxygen] Lactic acid + Energy}\]

Answer 1

\[\ce{Glucose -> Pyruvate ->[Lack of][oxygen] Lactic acid + Energy}\]

Explanation:

Anaerobic respiration is the breakdown of glucose in the absence of oxygen. In human muscle cells, this process leads to the formation of lactic acid. Glucose is first converted into pyruvate. In the absence of oxygen, pyruvate is converted into lactic acid with release of a small amount of energy
