Which of the following statements regarding Entner-Doudoroff pathway is true?

a. it involves glycolysis

b. NADH is generated

c. ATP is generated

d. it involves the pentose phosphate pathway

e. NADH and ATP are generated

C. ATP is generated

Explanation:

The Entner-Doudoroff pathway is one of the three glycolytic pathways that breakdown glucose into pyruvate. The Entner-Doudoroff pathway is the most common glycolytic pathway in microbes present in the soil such as Rhizobium, Azotobacter, etc.

The Entner-Doudoroff pathway forms glucose 6-phosphate from glucose which in turn is oxidized into 6-phosphogluconate. The 6-phosphogluconate finally forms pyruvate and glyceraldehyde 3-phosphate through a series of reactions. The glyceraldehyde 3-phosphate can enter the Embden-Meyerhof pathway to form one more molecule of pyruvate. During the Entner-Doudoroff pathway, one molecule of ATP and one NADPH are formed along with the formation of one molecule of each pyruvate and glyceraldehyde.
