Question

Which of the following is an advantage of metabolic channeling? a. It allows the product of one reaction to be available for a reaction later in another pathway. b. It does not allow for substrate dilution into the milieu and for the accumulation of intermediates. c. It allows the diffusion of substrates. d. It allows the dilution of substrates. e. It allows a more diverse interaction of substrates, intermediates, and enzymes.

Answer 1

Answer: b. It does not allow for substrate dilution into the milieu and for the accumulation of intermediates.

Explanation:

Molecular channeling or substrate channeling is a process which involves the passing of the metabolic products which are in the intermediary state towards different enzymes or active sites without being released into the solution. The channeling process ensures the complete synthesis of the products and the rapid, efficient and complete enzyme reactions. Hence, this process prevents the release of unstable intermediary products in the solution.
