Which of these is an odd one out?

Show answer & explanation

Correct answer: C

Explanation

The correct answer is Option 3 i.e. DNA.

DNA (Deoxyribonucleic acid) is the "odd one out" because it is a nucleic acid that functions as the primary genetic material for long-term information storage. In contrast, the other three molecules are directly involved in cellular energy metabolism.

Explanation of other options:

  • ATP (Adenosine Triphosphate): The primary "energy currency" of the cell, providing immediate energy for biological processes.

  • Glucose: A simple sugar that serves as the fundamental fuel source which cells break down to produce energy.

  • NADH: An electron carrier molecule produced during glycolysis and the Krebs cycle, essential for generating ATP in the mitochondria.
