Question

The number of substrate molecules converted to product in a given unit of time by a single enzyme molecule at saturation is referred to as the: dissociation constant maximum velocity turnover number Michaelis constant

Answer 1

Answer:

The correct answer is turnover number.

Explanation:

Michaelis–Menten 's equation:

$v=V_{max}\times \frac{[S]}{(K_m+[S])}=k_{cat}[E_o]\times \frac{[S]}{(K_m+[S])}$

$V_{max}=k_{cat}[E_o]$

v = rate of formation of products

[S] = Concatenation of substrate

$[K_m]$=  Michaelis constant

$V_{max}$ = Maximum rate achieved

$k_{cat}$ = Catalytic rate of the system = turn over number

$[E_o]$ = Initial concentration of enzyme.

The turn over number is defined as number of substrate molecules converted into product by enzyme molecule per second.
