Rxn catalysed by: (6-10)

Question 1

Adenylate cyclase

Answer 1

reaction from ATP to cAMP

Question 2

Adenylate kinase

Answer 2

phosphorylation of AMP to ADP by this enzyme.
ATP + AMP <–> 2 ADP

Question 3

Aconitase

Answer 3

catalyze reaction from citrate to cis-aconitate, and from cis-aconitate to isocitrate in krebs cycle

citrate <-> cis-Aconitate <-> isocitrate

Question 4

Alanine aminotransferase

Answer 4

catalyses the transfer of a -NH2 group from alanine to α-ketoglutarate forming pyruvate and glutamate

Question 5

Aspartate aminotransferase

Answer 5

glutamate + oxaloacetate <–> a-ketoglutarate + aspartate

*transamination
*anaplerotic rxn of Krebs cycle (replenish intermediates of Krebs cycle)
