Rxn catalysed by: (31-35)

Question 1

Invertase

Answer 1

(also called beta-fructofuranosidase or sucrase)
– catalyze hydrolysis of sucrose

Question 2

Isocitrate dehydrogenase

Answer 2

isocitrate –> [oxalosuccinate] –> a-ketoglutarate

*topic 27 Krebs cycle

Question 3

Lipase

Answer 3

catalyze hydrolysis of fats. E.g. triacylglycerol

Question 4

Ligase

Answer 4

Acetate forms Acetyl-CoA using Acetyl-CoA ligase using ATP
[ethanol metabolism]

Question 5

Lyase

Answer 5

cleave/form covalent bond without presence of water. Carboxylases, decarboxylases, synthases.
E.g. Glutamate to GABA (Gamma-AminoButyric Acid)

*topic 47 - AA decarboxylation
