During which conversion is another ATP synthesised?
Options
- AConversion of glucose to glucose 6-phosphate
- BConversion of fructose 6-phosphate to fructose 1, 6-bisphosphate
- CConversion of BPGA to 3-phosphoglyceric acid (PGA)
- DConversion of PEP to pyruvic acid
Correct answer
D. Conversion of PEP to pyruvic acid
Step-by-step solution
The fructose 1, 6-bisphosphate is split into dihydroxyacetone phosphate and 3-phosphoglyceraldehyde (PGAL). We find that there is one step where NADH + H+ is formed from NAD+ ; this is when 3-phosphoglyceraldehyde (PGAL) is converted to 1, 3-bisphosphoglycerate (BPGA). Two redox-equivalents are removed (in the form of two hydrogen atoms) from PGAL and transferred to a molecule of NAD+ . PGAL is oxidized and with inorganic phosphate to get converted into BPGA. The conversion of BPGA to 3-phosphoglyceric acid (PGA),
