Energy is liberated in the human body when glucose is oxidised through a complex series of reactions. The Krebs cycle is one stage in this series. In one reaction of the Krebs cycle, fumaric acid is converted into malic acid. $\text{HO}_2\text{CCH=CHCO}_2\text{H} \rightarrow \text{HO}_2\text{CCH(OH)CH}_2\text{CO}_2\text{H}$ Which reagents would be used to carry out this change in the laboratory?
- Aacidified $\text{KMnO}_4$
- B$\text{Br}_2\text{(aq)}$ followed by hot $\text{NaOH}\text{(aq)}$
- C$\text{H}_2\text{O}$ with $\text{Pt}$ catalyst
- Dsteam with $\text{H}_2\text{SO}_4$
