1
Q
endogenous
A
enzymes that are already there
2
Q

A
enzymes that are added
3
Q
enzyme class 1: oxidoreductases
A
oxidation-reduction reactions
4
Q
enzyme class 2: transferases
A
remove and transfer of functional groups
5
Q
hydrolases
A
cleavage of bonds with introduction of water
6
Q
lyases
A
cleavage of bonds (no H2O); introduce double bond
7
Q
isomerase
A
rearrangements
8
Q
ligases
A
formation of a linkage, with the use of ATP
9
Q
why will the inactivation rate go up when heating?
A
because of irreversible inactivation
10
Q
starch constist of:
A
- amylose (alpha-D-(1,4) linked glucosyl units)
- amylopectin (alpha-D-(1,4) & alpha-D-(1,6) glucosyl units)
11
Q
which enzymes are needed to degrade starch completely to glucose?
A
glucoamylase –> exo-enzyme
alpha-amylase –> endo-enzyme
