Question

End product of glycolysis is
A)Citric acid
B)Glyceraldehyde
C)Phosphoglyceraldehyde
D)Pyruvic acid

Answer 1

Hint: Glycolysis is an anaerobic reaction, and it is the sole cause of ATP in low oxygen conditions. The metabolism of glucose into two pyruvate molecules is glycolysis.

Complete answer:
The original stage in every respiratory system is glycolysis, literally meaning to break sugar. In order to generate energy, glycolysis involves breaking down a sugar (generally glucose, although fructose and other sugars can be used) into more manageable compounds. Two Pyruvate, two NADH, and two ATPP are the net end products of glycolysis.

Glycolysis is the mechanism by which one glucose molecule is converted into two molecules of pyruvate, two ions of hydrogen and two molecules of water. Through this process, the high energy intermediate molecules of ATP and NADH are synthesised.

For energy generation, glycolysis is used by all cells in the body.The final outcome of glycolysis is pyruvate in aerobic settings and lactate in anaerobic conditions. Pyruvate completes the loop of Krebs for further energy production.

The glycolysis process combined with the fermentation process is known as anaerobic respiration, which is basically anaerobic without air. There are two primary modes of prokaryotic fermentation: alcohol fermentation and lactate fermentation .

The two pyruvate molecules lose two oxygen molecules in the alcohol fermentation, and one carbon molecule is removed from the pyruvate and merges to become carbon dioxide. No carbon dioxide is released during lactate fermentation and the pyruvate is instead reduced by the oxidation of NADH into lactate. It is called Acetaldehyde, the remaining molecule.

Hence, the correct answer is option (D)

Note: Glycolysis is a mechanism that all species undergo and is thus the most basic and rudimentary of all energy processing processes. In order to release further energy, the by-products of glycolysis may be further digested. In the cytoplasm of a cell in a plant, glycolysis takes place. The first step of respiration is glycolysis.
