Question

What is the other name of glycolysis?
(a) EMP Pathway
(b) TCA Pathway
(c) HMS Pathway
(d) None of the above

Answer 1

Hint: Glycolysis is derived from the Greek word (glycon-for sugar and lysis- for splitting) which means splitting of sugar. Glycolysis was given by Gustav Embden, Otto Meyerhof, and J.Parnas. The other name of glycolysis is based on the names of these scientists.

Complete answer:
Glycolysis is a common step of both types of respiration. This scheme was given by Gustav Embden, Otto Meyerhof, and J.Parnas and thus is referred to as the EMP pathway or Embden- Meyerhof- Parnas pathway.
- Glycolysis is defined as partial oxidation of glucose to form two molecules of pyruvic acid. - It is the only process of respiration in anaerobic organisms. Glycolysis occurs in the cytoplasm of the cell. - In plants, the glucose is derived from sucrose, which is the end product of photosynthesis, or from the storage of carbohydrates. - Sucrose is converted into glucose and fructose by the enzyme, invertase, and these two monosaccharides readily enter the glycolytic pathway. In animals, starch is digested into glucose and that is used in the glycolysis.
So, the answer is, ‘EMP Pathway.’

Note:
- Glycolysis doesn’t require oxygen. - The first half of this pathway is called the glucose activation phase (activates glucose). The second half of the pathway extracts energy (energy extraction phase). - Fructose- 6- phosphate is phosphorylated to form fructose- 1,6- bisphosphate. This step is known as the rate- limiting step.
