Question

Arrange the following compounds in their correct sequence for glycolysis:

A. 3-phosphoglyceraldehyde
B. 1, 3-biphosphoglyceric acid
C. 2-phosphoglyceric acid
D. Phosphoenolpyruvic acid
E. Eructose 1, 6-biphosphate

Answer 1

The compounds for glycolysis, arranged in the correct order of occurrence in the pathway, are Fructose 1,6-bisphosphate, Glyceraldehyde-3-phosphate, 1,3-Bisphosphoglyceric acid, 2-phosphoglyceric acid, and Phosphoenolpyruvic acid.

Step-by-step explanation:

To arrange the given compounds in the correct sequence for glycolysis, we need to follow the pathway that glucose undergoes as it is converted into pyruvate. The correct sequence of the compounds provided from the glycolytic pathway is:

1. Fructose 1,6-bisphosphate (E)
2. Glyceraldehyde-3-phosphate (A)
3. 1,3-Bisphosphoglyceric acid (B)
4. 2-Phosphoglyceric acid (C)
5. Phosphoenolpyruvic acid (D)

Through this process, glucose initially undergoes phosphorylation to glucose-6-phosphate, then converted to fructose-6-phosphate, and further phosphorylated to fructose 1,6-bisphosphate. Next, fructose 1,6-bisphosphate is split into dihydroxyacetone phosphate and glyceraldehyde-3-phosphate. Then, the pathway continues through the creation of 1,3-bisphosphoglyceric acid, conversion to 2-phosphoglyceric acid, and culminates with the formation of phosphoenolpyruvic acid, leading to the final product, pyruvate.
