Explanation / Answer

31.Tryptophanase- Indole production

Explanation: Tryptophanase hydrolyses tryptophan to produce indole.

32. Amylase- Starch hydrolysis

Explanation: Amylase acts on the bonds of starch and makes them soluble.

33. cysteine desulfurase- Hydrofen sulfide production

Explanation: The enzyme cysteine desulfurase produces hydrogen sulfide from the amino acid cysteine.

34. Urease- ammonia production

Explanation: Urease converts urea into ammonia

35. Lipase- fat hydrolysis

Explanation: Lipase hydrolyses fat
