Factors that Affect the Rate of Enzyme Reactions:
Enzymes have a/an …..temperature at which they work fastest.
a) optimum
b) minimum
c) maximum
d) both b and c
For mammalian enzymes, the optimum temperature is about………°C.
a) 35
b) 25
c) 40
d) 45
The enzymes from
the arctic snow flea work at……..°C.
a) -30
b) -10
c) 4
d) -25
The enzymes from the thermophilic bacteria work at……..°C.
a) 60
b) 70
c) 90
d) -90
The increase in rate with temperature can quantified as a Q IO, which is the relative for a…….°C rise in temperature.
a) 0
b) 10
c) 40
d) 25
Explanation: the rate is not zero at 0°C. enzymes still work in fridge
