The number of ATPs produced by HMP shunt is: (A) Zero, (B) One, (C) Two, (D) Four
Answer is A. The number of ATPs produced by HMP shunt is zero HMP shunt/ Pentose Phosphate pathway Neither produces nor utilizes ATPs. 2 main products of HMP shunt: NADPH - in the irreversible oxidative phase Ribose-5-phosphate - In Reversible non-oxidative phase Rate limiting enzyme - Glucose-6-phosphate dehydrogenase. Extra Edge: The pathways producing Zero ATPs are: HMP (Hexose Monophosphate Pathway) Uronic Acid Pathway Alpha Oxidation Oxidation of Very Long Chain Fatty Acids (VLCFA) RL Shunt/cycle Synthesis of Ketone Bodies
