Question

question 8
one strategy that makes metabolic pathways more efficient is
enzymes for a given pathway are located in the same place within the cell
all of the reactions use the same substrate
all of the reactions use the same enzyme
enzymes for a pathway are separated into different organelles.

Explanation:

In cells, metabolic pathways are more efficient when enzymes for a given pathway are located in the same place within the cell. This allows for a sequential and rapid progression of reactions as products of one reaction can quickly become substrates for the next without having to diffuse over long distances within the cell. Different reactions in a pathway usually have different substrates and require different enzymes. Separating enzymes for a pathway into different organelles would make the pathway less efficient as it would increase the distance and time for intermediate - products to reach the next enzyme.

Answer:

enzymes for a given pathway are located in the same place within the cell
