Besides turning enzymes on or off, what other means does a cell use to control enzymatic activity?
a) localization of enzymes into specific organelles or membranes
b) exporting enzymes out of the cell
c) connecting enzymes into large aggregates
d) hydrophobic interactions

The correct answer is: A) localization of enzymes into specific organelles or membranes

There are many ways for the regulation of enzyme activity:

•By activators and inhibitors that bind to enzyme

•By cofactors- non-protein helper molecules

•Feedback inhibition (positive or negative)

•Compartmentalization- Storing enzymes in specific compartments (organelles) can provide the right or wrong conditions for enzyme activity.

organ system-an organ system is a group of organs that work together to perform one or more functions. each does a particular job in the body, and is made up of certain tissues.
