Which of these reactions is a multi step process?
Options
- AGlucose → Glucose - 6- phosphate
- BFumarate → Oxaloacetate
- CPEPA → PA
- DSuccinyl CoA → Succinate
Correct answer
B. Fumarate → Oxaloacetate
Step-by-step solution
The question involves two pathways of cellular respiration, glycolysis and Kreb's cycle. In glycolysis the first step involves the conversion of a glucose molecule to glucose-6-phosphate, and the last step where the Phosphoenolpyruvic acid (PEPA) is converted to two molecules of Pyruvic acid (PA) or pyruvate. During the Kreb's cycle, Succinyl- CoA is converted to succinate using the Succinyl-CoA synthetase enzyme and the fumarate gets converted to malate with the help of enzyme fumarase. Malate is then converted to
