Which of the following best describes an autocatalytic enzyme?
A
An enzyme that is inhibited by its own substrate.
B
An enzyme that requires a cofactor to function.
C
An enzyme that catalyzes the breakdown of itself.
D
An enzyme that catalyzes a reaction in which the product acts as a catalyst for the same reaction.
Verified step by step guidance1
Understand the term 'autocatalytic enzyme': An autocatalytic enzyme is one that catalyzes a reaction where the product of the reaction itself acts as a catalyst for the same reaction, amplifying the process.
Analyze the options provided: Carefully read each option and compare it to the definition of an autocatalytic enzyme.
Option 1: 'An enzyme that is inhibited by its own substrate' - This describes feedback inhibition, not autocatalysis.
Option 2: 'An enzyme that requires a cofactor to function' - This describes enzymes that depend on cofactors, but it is unrelated to autocatalysis.
Option 3: 'An enzyme that catalyzes the breakdown of itself' - This describes self-degradation, not autocatalysis. The correct answer is Option 4: 'An enzyme that catalyzes a reaction in which the product acts as a catalyst for the same reaction.'
