Question

How many ATP equivalent energy will be produced by HMP shunt?
A. 40 ATP
B. 38 ATP
C. 35 ATP
D. 8 ATP

Answer 1

The hexose monophosphate shunt is also called the phosphogluconate pathway and the pentose phosphate pathway. It is a metabolic pathway corresponding to glycolysis. It creates $NADPH$ and pentoses (5-Carbon sugars) just as ribose 5-phosphate, an antecedent for the union of nucleotides. While the pentose phosphate pathway includes oxidation of glucose, its essential job is anabolic instead of catabolic. The pathway is particularly significant in erythrocytes.

Complete answer:
Hexose monophosphate involves two main stages:
- The principal is the oxidative stage, in which NADPH is produced, and
- The second is the non-oxidative amalgamation of 5-carbon sugars. For most life forms, the pentose phosphate pathway happens in the cytosol; in plants, most advances occur in plastids.

The essential consequences of the pathway are:
- The age of lessening counterparts, as NADPH, is utilized in reductive biosynthesis responses inside cells.
- Creation of ribose 5-phosphate $(R5P)$ utilized in the combination of nucleotides and nucleic acids.
- Creation of erythrose 4-phosphate $(E4P)$ utilized in the combination of sweet-smelling amino acids.
- Fragrant amino acids, thus, are forerunners for some, biosynthetic pathways, remembering the lignin for wood.
- In the whole process, 12 pairs of hydrogen atoms are transferred to oxygen yielding $12 \times 3 = 36$ ATP. But only 1 ATP is used to convert one molecule of free glucose 6-phosphate. Hence, the outcome is 35 ATP.

Hence, the correct answer is option (B).

Note: In warm-blooded animals, this pathway happens solely in the cytoplasm. In people, it is discovered to be generally dynamic in the liver, mammary organs, and adrenal cortex. This process is one of the three principal ways the body makes atoms with decreasing force, representing roughly 60% of NADPH creation in humans.
