Read the following statements regarding the biochemical events in glycolysis and choose the incorrect statement.
Options
- AATP is utilized during the conversion of glucose to glucose-6-phosphate.
- BThe conversion of 1,3-bisphosphoglyceric acid to 3-phosphoglyceric acid synthesizes ATP.
- CNADH + H ⁺ is produced during the conversion of 3-phosphoglyceraldehyde to 1,3-bisphosphoglyceric acid.
- DATP is utilized when fructose-1,6-bisphosphate splits into 3-phosphoglyceraldehyde and dihydroxyacetone phosph
Correct answer
D. ATP is utilized when fructose-1,6-bisphosphate splits into 3-phosphoglyceraldehyde and dihydroxyacetone phosph
Step-by-step solution
Statement 4 is incorrect. The splitting of the 6-carbon molecule fructose-1,6-bisphosphate into two 3-carbon molecules, 3-phosphoglyceraldehyde (PGAL) and dihydroxyacetone phosphate (DHAP), is a cleavage reaction and does not utilize ATP. Statement 1 is correct because the first ATP in glycolysis is consumed to phosphorylate glucose into glucose-6-phosphate. Statement 2 is correct as the conversion of 1,3-bisphosphoglyceric acid (BPGA) to 3-phosphoglyceric acid (PGA) is a substrate-level phosphorylation step that y
