Figure 1 shows a protein enzyme labeled E that catalyzes a chemical reaction involving the substrate molecule labeled C.Figure 2 shows how another molecule, labeled D, binds to a site on the protein that is distinct from the catalytic site. Based on the activities shown, what biological advantage does this protein gain by having the ability to bind molecule D?

Figure 1 shows a protein enzyme labeled E that catalyzes a chemical reaction involving the substrate molecule labeled C.Figure 2 shows how another molecule, labeled D, binds to a site on the protein that is distinct from the catalytic site.  Based on the activities shown, what biological advantage does this protein gain by having the ability to bind molecule D?

Quizplus · Accepted Answer

By binding molecule D at a site distinct from the catalytic site, the protein gains the ability to regulate its biological activity. This allows the protein to turn its activity on and off as needed, providing a mechanism for fine-tuning cellular processes.
