Which of the following statements about the Entner-Doudoroff pathway is false? a. It is a series of reactions that synthesizes glucose. b. Its products are sometimes used to determine the presence of Pseudomonas. c. It is a pathway of chemical reactions that catabolizes glucose. d. It is an alternative pathway to glycolysis.

Hey, everyone. Let's take a look at this question together which among these assertions related to the Ner DAO pathway isn't valid. Is it answer choice? A pyruvate acts as one among many final products produced through this path. Answer choice B glucose acts as an initial substrate for this process. Answer choice C aerobic respiration follows after completion of the Ed pathway or answer choice D glucose gets synthesized through this process. Let's work this problem out together to try to figure out which of the following answer choices is an assertion related to the Ner Dairo pathway that is not valid. So in order to solve this question, we have to recall what we have learned about the DAO pathway or the Ed pathway to determine which among these assertions related to that pathway is not valid. And we can recall that the Ner Daer off or Ed pathway involves breaking down glucose into pyruvate and glyceraldehyde three phosphate. So looking at our answer choices, starting off with answer choice A which says Pyruvate acts as one among many final products produced through this path, which we know is true as the ED pathway involves breaking down glucose into pyruvate. So answer choice A cannot be the correct answer. Next. We have answer choice B which says that glucose acts as an initial substrate or this process, which we know is also true as this pathway involves the breaking down of glucose. So answer choice B cannot be the correct answer either. Then we have answer choice C which says aerobic respiration follows after completion of the ed path pathway which we know that once glucose is broken down into pyruvate and glyceraldehyde three phosphate, when the conditions are ideal aerobic respiration does follow after completion of that pathway. So answer choice C is also true, which means it cannot be the correct answer either. Therefore, answer choice D is the correct answer as it is the only remaining answer choice. And it says that glucose gets synthesized through this process, which we know is not valid as glucose does not get synthesized through this process. And instead glucose degrades into other compounds such as pyruvate and glyceraldehyde three phosphate. So answer choice D is the correct answer. I hope you found this video to be helpful.
