What happens during the conversion of BPGA to 3-phosphoglyceric acid (PGA)?
Options
- AEnergy is trapped by the formation of NADH
- BEnergy is trapped by the formation of ATP
- CATP is utilized
- DWater is produced
Correct answer
B. Energy is trapped by the formation of ATP
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),
