Question

Which of the following is a direct oxidation pathway performed without glycolysis cycle?

• A. HMP pathway
• B. TCA
• C. Both of A and B
• D. None of the above

Answer 1

The correct option is A HMP pathway

The HMP pathway or pentose phosphate pathway that produces 5 carbon compound and NADPH in the form of energy. Additionally, these pathways can operate in the anabolic direction to transform glycolytic intermediates into other compounds. So, HMP pathway is a direct oxidation pathway performed without glycolysis cycle. HMP shunt produces some glycolytic intermediated like glyceraldehyde-3-phosphate and fructose-6-phosphate that can directly involve in the glycolysis pathway or EMP. Thus, the correct answer is option A.
