Which kind of poison would most likely directly interfere with glycolysis?

a. A poison that binds to pyruvate and inactivates it.

b. A poison that blocks the passage of electrons along the electrontransport chain.

c. A poison that closely mimics the structure of glucose but is not metabolized.

d. A poison that reacts with oxygen and depletes its concentrationin the cell.

Answer: c. A poison that closely mimics the structure of glucose but is not metabolized.

Glycolysis is known as the process by which a Glucose molecule is metabolized in the cellular to produce ATP and pyruvate. Any substance that had something like glucose but is not a substrate for metabolism would through itself into this process. The type of poison would be glucophagous with glycolytic abilities The type of poison is that it would attach to the glucose to replicate the glycolytic pathway but as it cannot be metabolized it would hence slow or even stop the ability of glucose to be metabolized. In the end, this would stop the whole process of glycolysis and a cell would not be able to use this pathway for obtaining energy at all. The other options as much as they may affect cellular respiration and energy production in some other ways, will not interfere directly with the first step of glycolysis.
