Which statement most accurately explains how allosteric regulation can change an enzyme's activity?
a. In allosteric deactivation a regulatory molecule binds to a site other than the active site, resulting in a change in enzyme shape that allows the active site to bind substrate.
b. In allosteric activation a regulatory molecule binds to the active site, allowing substrate binding.
c.In allosteric activation a regulatory molecule binds to a site other than the active site, resulting in a change in enzyme shape that allows the active site to bind substrate.
d.In allosteric deactivation a regulatory molecule binds to the active site, blocking substrate binding.

When O2 binds to heme in hemoglobin, the is drawn into the plane of the porphyrin, causing conformational change that is transmitted to adjacent subunits.
Discuss and explain how you would calculate delta G for the reaction: glucose+6O2---> 6CO2+6H2O. If you were told that this reaction is highly exergonic.
During mitosis it is important for sister chromatids to stick together (called "cohesion") during some stages and then separate. Researchers have identified proteins called "cohesins" that are involved in sister chromatid cohesion. If you wanted t..
