WebSep 15, 2010 · How do most cells regulate the activity of enzymes? Enzyme speeds up the chemical reaction. So, it would speed the cells for life and live. WebIn order to drive the cell cycle forward, a cyclin must activate or inactivate many target proteins inside of the cell. Cyclins drive the events of the cell cycle by partnering with a family of enzymes called the cyclin-dependent kinases ( Cdks ).
WebIn a most efficient and elegant way, cells have evolved to use their own reactions' products for feedback inhibition of enzyme activity.
