Detailed explanation-1: -The hexose monophosphate shunt, also known as the pentose phosphate pathway, is a unique pathway used to create products essential in the body for many reasons. The HMP shunt is an alternative pathway to glycolysis and is used to produce ribose-5-phosphate and nicotinamide adenine dinucleotide phosphate (NADPH).

Detailed explanation-2: -The pentose phosphate pathway (PPP) branches from glucose 6-phosphate (G6P), produces NADPH and ribose 5-phosphate (R5P), and shunts carbons back to the glycolytic or gluconeogenic pathway.

Detailed explanation-3: -The pentose phosphate pathway is a metabolic pathway that occurs in the cytoplasm for the production of NADPH from NADP. In this pathway oxidation of glucose 6-phosphate takes place to produce pentoses. Thus it is also known as hexose monophosphate shunt.

Detailed explanation-4: -Pentose phosphate pathway is an alternative route for the oxidation of glucose. It is the pathway for the formation of pentose sugar. It is also known as hexose monophosphate shunt (HMP shunt).

Detailed explanation-5: -The glycolysis and pentose phosphate pathways (PPP) are tightly connected. The glucose entering the in cell membrane is rapidly phosphorylated by HK and converted to G-6-P. The G-6-P is metabolized either by the glycolytic pathway, generating pyruvate and lactate, or by PPP to produce NADPH.
