How pH affects enzymes
Too high or too low bonds not in place in active site so enzyme denatures
Optimum pH for enzymes
7
Optimum temperature for enzymes
37
what happens to enzymes when temp too high or too low
too low - don’t work/nothing
too high- denatures
What is lock and key mechanism
when substrate fits into active site of enzyme
Describe how enzyme works in a chemical reaction
Active site specific for substrate
bond two substrates together
break substrates down
enzyme not used up or altered.
