Question

HMP shunt is a set of reaction which is
A. Also called as pentose phosphate pathway
B. Bypasses EMP route of glucose oxidation
C. Both A and B
D. Which convert glucose to phosphoglycerate

Answer 1

Hint:
Glycolysis products are sent through the rest of the cellular respiration to generate energy, there is also an alternate branch of glycolysis to generate sugars that make up DNA and RNA.

Complete solution:
The main objective of the HMP pathway is to produce reduced NADPHs and pentose phosphates (for nucleotide synthesis). Oxidative and non-oxidative phases are present in the HMP shunt pathway.
Glucose-6-phosphate is oxidized during the oxidative process by producing two NADPH molecules and one pentose phosphate molecule accompanied with a release of a carbon dioxide molecule and thus named as the pentose-phosphate pathway.
HMP shunt generates some glycolytic intermediates which may have a direct effect in the pathway to glycolysis or EMP.

Hence, the option (C) is the correct choice.

Additional Information:
Another way for the body to use glucose is the pentose phosphate pathway. The pathway is important because it is how our bodies produce molecules for other processes, such as ribose-5-phosphate, which is a precursor to RNA or DNA, and erythrose-4-phosphate, which is used as an amino acid precursor. For this process, it is important to note that the non-oxidative stage is reversible so that the molecule can join at any point and be transformed to whatever the body requires to be, be it energy or RNA materials or amino acids.

Note:
HMP pathway also known as the pentose phosphate pathway as it produces a pentose phosphate that can be used in the generation of nucleic acids. It is an alternate way to use glucose that bypasses the oxidation of glucose via EMP pathway.
