Question

In carrier protein function kinetics, Km is the

A) maximal rate of solute transport.
B) solute concentration at which the transport rate is half maximal.
C) initial rate of transport at any concentration.
D) constant rate of transport regardless of concentration gradient.
E) standard free energy change used to calculate the maximal rate of transport.

Answer 1

Km in carrier protein function kinetics refers to the solute concentration at which the transport rate is half maximal.

Step-by-step explanation:

The Km in carrier protein function kinetics refers to the solute concentration at which the transport rate is half maximal. It is defined as the substrate concentration at which the velocity of the enzyme catalyzed reaction is half the maximum velocity.
