Question

(a) 600 c=0 CH + NADH + H - 500- + NAD HO-- CH, COO H-CH(CH HỘI NH ADP + P 5. On the free energy diagram shown, label the intermediate(s) and transition state(s). Is the reaction thermodynamically favorable? 6. Urcase, the first enzyme to be crystallized, is inhibited in the presence of Hg, Cd, or Co ions What does this information suggest about the catalytic mechanism of urease?

First question: Which type of enzyme fron table 11-2 catalyzes the following reactions

Answer 1

(a). Pyruvate is converted into lactate where a substrate molecule got reduced and NADH2 got oxidised. Since oxidation and reduction is happening here, This type of reaction is catalysed by Oxidoreductases enzyme.

(b). Transfer of amino group to glutamic acid is taking place with the hydrolysis of ATP molecule. So this type of reaction is catalysed by Ligases.
