The Michaelis-Menten constant for an enzyme-catalysed reaction is referred to as ${K_m}$, and the maximum velocity of such a reaction is known as ${V_{\max }}$.
Which statement about ${K_m}$ and ${V_{\max }}$ is correct?
1 )
An enzyme with a high value of ${K_m}$ can reach its ${V_{\max }}$ at a low substrate concentration.
2 )
An enzyme with a high value of ${K_m}$ has a high affinity to its substrate.
3 )
An enzyme with a low value of ${K_m}$ can reach its ${V_{\max }}$ at a high substrate concentration.
An enzyme with a low value of ${K_m}$ has a high affinity to its substrate.
