The glycolysis pathway was invented by(A) Calvin(B) Kreb(C) J.C Bose(D) None of the above

The correct answer is D) None of the above.
1. What is Glycolysis?
o Glycolysis is a central metabolic pathway in cellular respiration, where glucose (a 6-carbon sugar) is broken down into pyruvate (a 3-carbon compound), releasing energy in the form of ATP.
o It occurs in the cytoplasm of cells and is common to almost all living organisms, serving as a fundamental process for energy production.
2. Discovery of Glycolysis:
o The glycolysis pathway was elucidated by a series of scientists, most notably Gustav Embden, Otto Meyerhof, and Jakob Parnas. As a result, the pathway is often referred to as the Embden-Meyerhof-Parnas (EMP) pathway.
o These scientists worked during the early 20th century to detail the enzymatic steps and intermediates involved in glycolysis.
3. Why Not the Given Options?
o A) Calvin: Melvin Calvin discovered the Calvin cycle, a photosynthetic pathway in plants, not glycolysis.
o B) Kreb: Hans Krebs discovered the Krebs cycle (citric acid cycle), which is a part of aerobic respiration following glycolysis.
o C) J.C. Bose: Jagadish Chandra Bose was a pioneering Indian scientist who worked on plant physiology and biophysics but did not contribute to the discovery of glycolysis.
4. None of the Above:
o The glycolysis pathway was discovered and described by Embden, Meyerhof, and Parnas, making D) None of the above the correct choice.
The glycolysis pathway was discovered by Embden, Meyerhof, and Parnas, and none of the options listed are correct. Therefore, the correct answer is D) None of the above.
