Km is defined as A: Substrate concentration at maximum velocity B: Substrate concentration at half the maximum velocity C: Enzyme concentration D: Optimum temperature
Km is defined as A: Substrate concentration at maximum velocity B: Substrate concentration at half the maximum velocity C: Enzyme concentration D: Optimum temperature
In general, a small KM indicates that a substrate binds very tightly to the enzyme, and a large KM indicates weak binding.
