NEET Questions / Botany / Respiration in Plants / Glycolysis
In a hypothetical scenario, a cell has a mutated form of aldolase that cleaves fructose 1,6-bisphosphate into two molecules of dihydroxyacetone phosphate. How many net ATP molecules would be produced from one molecule of glucose under anaerobic conditions in this cell?
0 ATP
2 ATP
4 ATP
6 ATP
Imagine a scenario where a cell expresses a mutated form of glyceraldehyde-3-phosphate dehydrogenase that uses inorganic phosphate but does not reduce NAD+ to NADH. What is the fate of the high-energy phosphate group acquired during this altered reaction in the subsequent steps of glycolysis under anaerobic conditions?
It is lost as inorganic phosphate during the conversion to 2-phosphoglycerate.
It is transferred to ADP to form ATP by phosphoglycerate kinase.
It remains attached to the 3-carbon molecule and is ultimately incorporated into lactate.
It is used to phosphorylate another glucose molecule, priming it for entry into glycolysis.
