Cells were allowed to bind to beads that had been covered with a coating of fibronectin. When the membrane-bound beads were pulled by an optical tweezer, the resultant mechanical stimulus was transmitted into the cell interior. What response did this cause?
A)It generated a wave of Src kinase activity.
B)It caused nuclear shrinkage.
C)It caused activation of phosphofructokinase.
D)It caused inhibition of phosphofructokinase.
E)It inhibited Src kinase activity.
