Induction of beta galactosidase is under control of
A
Lac operon
4
Q
System that phosphorylates lactose vía a specific enzyme II
A
PEP phosphotramsferase system (PTS)
5
Q
Cellulose structure
A
Beta 1,4 linked glucose polymer occurring in crystalline or amorphous forms
6
Q
3 enzymes involved in cellulose degradation and functions
A
- Endo beta 1,4 glucanase : cleaves cellulose to smaller oligosaccharides with free chain ends
- Exo beta 1,4 glucanase : remove disaccharide cellobiose units from reducing/non reducing ends of oligosaccharide
- Beta glucosidase: cellobiose hydrolyzed to glucose
